Chapter 5 FUNCTION CODES
5.1 Function Code Tables
Function codes enable the FRENIC-Mini series of inverters to be set up to match your system requirements.
Each function code consists of a 3-letter alphanumeric string. The first letter is an alphabet that identifies its group and the following two letters are numerals that identify each individual code in the group. The function codes are classified into eight groups: Fundamental Functions (F codes), Extension Terminal Functions (E codes), Control Functions (C codes), Motor 1 Parameters (P codes), High Performance Functions (H codes), Motor 2 Parameters (A codes), Application Functions (J codes) and Link Functions (y codes). To determine the property of each function code, set data to the function code.
The following descriptions supplement those given in the function code tables on page 5-3 and subsequent pages.
Changing, validating, and saving function code data when the motor is running
Function codes are indicated by the following based on whether they can be changed or not when the inverter is running:
Notation Change when running
Validating and saving function code data
Y*
Possible
If the data of the codes marked with Y* is changed, the change
will immediately take effect; however, the change is not saved
into the inverter's memory. To save the change, press the
key. If you press the key without pressing the key to exit
the current state, then the changed data will be discarded and
the previous data will take effect for the inverter operation.
Y
Possible
The data of the codes marked with Y can be changed with the
and keys regardless of whether the motor is running or
not. Pressing the key will make the change effective and
save it into the inverter's memory.
N
Impossible
Copying data
Connecting an optional remote keypad enables you to copy the function code data stored in the inverter's memory into the keypad's memory (refer to Menu #7 "Data copying" in Programming mode). With this feature, you can easily transfer all function code data saved in a source inverter to other destination inverters.
If the specifications of the source and destination inverters differ, some code data may not be copied to ensure safe operation of your power system. Therefore, you need to set up the uncopied code data individually as necessary. Whether data will be copied or not is detailed with the following symbols in the "Data copy" column of the function code tables given below. Y: Will be copied unconditionally. Y1: Will not be copied if the rated capacity differs from the source inverter. Y2: Will not be copied if the rated input voltage differs from the source inverter. N: Will not be copied. (Function codes marked with an "N" are not subject to Verify operation,
either.)
5-1
It is recommended that you set up those function codes which are not subject to the Copy operation individually using Menu #1 "Data setting" as necessary.
Refer to the Remote Keypad Instruction Manual (INR-SI47-0843-E) for details.
Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for digital input terminals and transistor output terminals by setting the function code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to active-OFF signal (the function takes effect if the terminal is opened.) in the negative logic system. An active-ON signal can be switched to active-OFF signal, and vice versa, with the function code data setting.
To set the negative logic system for an input or output terminal, enter data of 1000s (by adding 1000 to the data for the normal logic) in the corresponding function code.
Example: "Coast to a stop" command BX assigned to any of digital input terminals [X1] to [X3] using any of function codes E01 through E03.
Function code data 7
1007
BX Turning BX ON causes the motor to coast to a stop. (Active ON) Turning BX OFF causes the motor to coast to a stop. (Active OFF)
Limitation of data displayed on the LED monitor Only four digits can be displayed on the 4-digit LED monitor. If you enter more than 4 digits of data valid for a function code, any digits after the 4th digit of the set data will not be displayed; however they will be processed correctly.

5.2 Details of Function Codes
This section provides the details of the function codes frequently used for the FRENIC-Mini series of inverters.
For details about the function codes given below and other function codes not given below,
refer to the FRENIC-Mini
Manual (24A7-E-0023), Chapter 9 "FUNCTION CODES."
F00
Data Protection
F00 specifies whether to protect function code data (except F00) and digital reference data (such as frequency command, PID command and timer operation) from accidentally getting changed by pressing the / keys.
Data for F00 0 1 2 3
Function
Disable both data protection and digital reference protection, allowing you to change both function code data and digital reference data with the / keys.
Enable data protection and disable digital reference protection, allowing you to change digital reference data with the / keys. But you cannot change function code data (except F00).
Disable data protection and enable digital reference protection, allowing you to change function code data with the / keys. But you cannot change digital reference data.
Enable both data protection and digital reference protection, not allowing you to change function code data or digital reference data with the
/ keys.
Enabling the protection disables the / keys to change function code data. To change F00 data, simultaneous keying of + (from 0 to 1) or + (from 1 to 0) keys is required.
Even when F00 = 1 or 3, function code data can be changed via the communications link. For similar purposes, WE-KP, a signal enabling editing of function code data from the keypad is provided as a terminal command for digital input terminals. (Refer to the descriptions of E01 through E03.)
F01, C30 Frequency Command 1, Frequency Command 2

4 7
Function
Enable the current input to terminal [C1] (+4 to +20 mA DC or 0 to +20 mA DC, maximum frequency obtained at +20 mA DC).
Using function code C40 expands the input range from "+4 to +20 mA DC" to "0 to +20 mA DC."
Enable the sum of voltage (0 to +10 VDC, maximum frequency obtained at +10 VDC) and current inputs (+4 to +20 mA DC or 0 to +20 mA DC, maximum frequency obtained at +20 mA DC) given to terminals [12] and [C1], respectively.
Using function code C40 expands the input range from "+4 to +20 mA DC" to "0 to +20 mA DC." Note: If the sum exceeds the maximum frequency (F03, A01), the maximum frequency will apply.
Enable the built-in potentiometer (POT). (Maximum frequency obtained at full scale of the POT)
Enable UP and DOWN commands assigned to the digital input terminals. The UP and DOWN should be assigned to any of digital input terminals [X1] to [X3] beforehand with any of E01 to E03 (data = 17 and 18).
In addition to the frequency command sources described above, higher priority command sources including communications link and multistep frequency are provided. For details, refer to the block diagram given in FRENIC-Mini User's Manual (24A7-E-0023), Chapter 4, Section 4.2 "Drive Frequency Command Generator."
For frequency settings made by terminals [12] (voltage) and [C1] (current) and by the built-in potentiometer, setting the gain and bias changes the relationship between those frequency settings and the drive frequency. Refer to function code F18 for details.
For the inputs to terminals [12] (voltage) and [C1] (current), low-pass filters can be enabled.
Using the terminal command Hz2/Hz1 assigned to one of the digital input terminals switches between frequency command 1 (F01) and frequency command 2 (C30). Refer to function codes E01 to E03.

Description
Enable the / keys to run and stop the motor. The rotation direction of the motor is specified by terminal command FWD or REV.
Enable terminal command FWD or REV to run and stop the motor. Enable / keys to run and stop the motor. Note that this run command enables only the forward rotation. There is no need to specify the rotation direction.
5-22
Data for F02 3
Run Command Source
Keypad (Reverse rotation)
Description
Enable / keys to run and stop the motor. Note that this run command enables only the reverse rotation. There is no need to specify the rotation direction.
When function code F02 = 0 or 1, the "Run forward" FWD and "Run reverse" REV terminal commands must be assigned to terminals [FWD] and [REV], respectively.
When the FWD or REV is ON, the F02 data cannot be changed.
When assigning the FWD or REV to terminal [FWD] or [REV] with F02 being set to "1," be sure to turn the target terminal OFF beforehand; otherwise, the motor may unintentionally rotate.
In addition to the run command sources described above, higher priority command sources including communications link are provided. For details, refer to the FRENIC-Mini User's Manual (24A7-E-0023).
F03
Maximum Frequency 1
F03 specifies the maximum frequency (for motor 1) to limit the output frequency. Specifying the maximum frequency exceeding the rating of the equipment driven by the inverter may cause damage or a dangerous situation. Make sure that the maximum frequency setting matches the equipment rating.
The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the specifications of motors or equipment beforehand. Otherwise injuries could occur.
Modifying F03 data to allow a higher reference frequency requires also changing F15 data specifying a frequency limiter (high).

H52, H53
Base Frequency 1 Rated Voltage at Base Frequency 1 Maximum Output Voltage 1 Non-linear V/f Pattern 1 (Frequency and Voltage) Non-linear V/f Pattern 2 (Frequency and Voltage)
These function codes specify the base frequency and the voltage at the base frequency essentially required for running the motor properly. If combined with the related function codes H50 through H53, these function codes may profile the non-linear V/f pattern by specifying increase or decrease in voltage at any point on the V/f pattern.
The following description includes setups required for the non-linear V/f pattern.
At high frequencies, the motor impedance may increase, resulting in an insufficient output voltage and a decrease in output torque. This feature is used to increase the voltage with the maximum output voltage 1 to prevent this problem from happening. Note, however, that you
5-23
Base Frequency 1 (F04) Set the rated frequency printed on the nameplate labeled on the motor.
Rated Voltage at Base Frequency (F05) Set "0" or the rated voltage printed on the nameplate labeled on the motor. - If "0" is set, the rated voltage at base frequency is determined by the power source of the
inverter. The output voltage will vary in line with any variance in input voltage. - If the data is set to anything other than "0," the inverter automatically keeps the output
voltage constant in line with the setting. When any of the auto torque boost settings, auto energy saving or slip compensation is active, the voltage settings should be equal to the rated voltage of the motor. Non-linear V/f Patterns 1 and 2 for Frequency (H50 and H52) Set the frequency component at an arbitrary point of the non-linear V/f pattern. (Setting "0.0" to H50 or H52 disables the non-linear V/f pattern operation.) Non-linear V/f Patterns 1 and 2 for Voltage (H51 and H53) Sets the voltage component at an arbitrary point of the non-linear V/f pattern. Maximum Output Voltage (F06) Set the voltage for the maximum frequency 1 (F03).
If F05 (Rated Voltage at Base Frequency 1) is set to "0," settings of H50 through H53 and F06 do not take effect. (When the non-linear point is below the base frequency, the linear V/f pattern applies; when it is above, the output voltage is kept constant.) When the auto torque boost (F37) is enabled, the non-linear V/f pattern takes no effect. Examples: Normal (linear) V/f pattern

F07 specifies the acceleration time, the length of time the frequency increases from 0 Hz to the maximum frequency. F08 specifies the deceleration time, the length of time the frequency decreases from the maximum frequency down to 0 Hz.
Selecting an S-shaped pattern or curvilinear acceleration/deceleration pattern with function code H07 (Acceleration/deceleration pattern) makes the actual acceleration/deceleration times longer than the specified ones. Refer to the descriptions of function code H07. Specifying an improperly short acceleration/deceleration time may activate the current limiter or anti-regenerative control, resulting in a longer acceleration/ deceleration time than the specified one. Acceleration/deceleration time 1 (F07, F08) and acceleration/deceleration time 2 (E10, E11) are switched by terminal command RT1 assigned to any of the digital input terminals with any of function codes E01 through E03.

Note: If a required "load torque + acceleration toque" is more than 50% of the rated torque, it is recommended to select the linear V/f pattern (factory default).
V/f characteristics
The FRENIC-Mini series of inverters offers a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans and pumps or for special pump load requiring high starting torque. Two types of torque boost are available: manual and automatic.
Variable torque V/f pattern (F37 = 0)
Linear V/f pattern (F37 = 1)
When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low and insufficient voltage output may result in less output torque of the motor at a low frequency zone, depending on some characteristics of the motor itself and load. In such a case, it is recommended to increase the output voltage at the low frequency zone using the non-linear V/f pattern (H50, H51).
Recommended value: H50 = 1/10 of the base frequency H51 = 1/10 of the voltage at base frequency
5-26
Torque boost Manual torque boost (F09) In torque boost using F09, constant voltage is added to the basic V/f pattern, regardless of the load, to give the output voltage. To secure a sufficient starting torque, manually adjust the output voltage to optimally match the motor and its load by using F09. Specify an appropriate level that guarantees smooth start-up and yet does not cause over-excitation with no or light load. Torque boost per F09 ensures high driving stability since the output voltage remains constant regardless of the load fluctuation. Specify the F09 data in percentage to the rated voltage at base frequency 1 (F05). At factory shipment, F09 is preset to a level that provides approx. 100% of starting torque.
Specifying a high torque boost level will generate a high torque, but may cause overcurrent due to over-excitation at no load. If you continue to drive the motor, it may overheat. To avoid such a situation, adjust torque boost to an appropriate level. When the non-linear V/f pattern and the torque boost are used together, the torque boost takes effect below the frequency on the non-linear
5-27
Auto torque boost
This function automatically optimizes the output voltage to fit the motor with its load. Under light load, auto torque boost decreases the output voltage to prevent the motor from over-excitation. Under heavy load, it increases the output voltage to increase output torque of the motor.
Since this function relies also on the characteristics of the motor, set the base frequency 1 (F04), the rated voltage at base frequency 1 (F05), and other pertinent motor parameters (P02, P03 and P06 through P99) in line with the motor capacity and characteristics, or else perform auto-tuning (P04).
When a special motor is driven or the load does not have sufficient rigidity, the maximum torque might decrease or the motor operation might become unstable. In such cases, do not use auto torque boost but choose manual torque boost per F09 (F37 = 0 or 1).
Auto energy saving operation
This feature automatically controls the supply voltage to the motor to minimize the total power loss of motor and inverter. (Note that this feature may not be effective depending upon the motor or load characteristics. Check the advantage of energy saving before actually apply this feature to your power system.)
This feature applies to constant speed operation only. During acceleration/deceleration, the inverter will run with manual torque boost (F09) or auto torque boost, depending on the F37 data. If auto energy saving operation is enabled, the response to a change in motor speed may be slow. Do not use this feature for such a system that requires quick acceleration/ deceleration.
Use auto energy saving only where the base frequency is 60 Hz or lower. If the base frequency is set at 60 Hz or higher, you may get a little or no energy saving advantage. The auto energy saving operation is designed for use with the frequency lower than the base frequency. If the frequency becomes higher than the base frequency, the auto energy saving operation will be invalid.
Since this function relies also on the characteristics of the motor, set the base frequency 1 (F04), the rated voltage at base frequency 1 (F05), and other pertinent motor parameters (P02, P03 and P06 through P99) in line with the motor capacity and characteristics, or else perform auto-tuning (P04).

Electronic Thermal Overload Protection for Motor 1 (Select motor characteristics) Electronic Thermal Overload Protection for Motor 1 (Overload detection level) Electronic Thermal Overload Protection for Motor 1 (Thermal time constant)
F10 through F12 specify the thermal characteristics of the motor for its electronic thermal overload protection that is used to detect overload conditions of the motor.
F10 selects the motor cooling mechanism to specify its characteristics, F11 specifies the overload detection current, and F12 specifies the thermal time constant.
Thermal characteristics of the motor specified by F10 and F12 are also used for the overload early warning. Even if you need only the overload early warning, set these characteristics data to these function codes. To disable the electronic thermal overload protection, set function code F11 to "0.00."

When F10 = 2, the cooling effect is not decreased by the output frequency so that the overload detection level is a constant value without reduction (F11).
Overload detection level (F11)
F11 specifies the detection level (in amperes) at which the electronic thermal overload protection becomes activated.
In general, set F11 to the rated current of motor when driven at the base frequency (i.e. 1.0 to 1.1 multiple of the rated current of motor 1 (P03)). To disable the electronic thermal overload protection, set F11 to "0.00: Disable."
Thermal time constant (F12)
F12 specifies the thermal time constant of the motor. If the current of 150% of the overload detection level specified by F11 flows for the time specified by F12, the electronic thermal overload protection becomes activated to detect the motor overload. The thermal time constant for general-purpose motors including Fuji motors is approx. 5 minutes by factory default.
- Data setting range: 0.5 to 75.0 (minutes) in increments of 0.1 (minute)
(Example) When the F12 data is set at "5.0" (5 minutes)
As shown below, the electronic thermal overload protection is activated to detect an alarm
condition (alarm code
) when the output current of 150% of the overload detection level
(specified by F11) flows for 5 minutes, and 120% for approx. 12.5 minutes.
The actual time required for issuing a motor overload alarm tends to be shorter than the specified value, taking into account the time period from when the output current exceeds the allowable continuous drive current (100%) until it reaches 150% of the overload detection level.

Description
As soon as the DC link bus voltage drops below the undervoltage detection level due to a momentary power failure, the inverter issues undervoltage alarm and shuts down its output so that the motor enters a coast-to-stop state.
As soon as the DC link bus voltage drops below the undervoltage detection level due to a momentary power failure, the inverter shuts down its output so that the motor enters a coast-to-stop state, but it does not enter the undervoltage state or issue undervoltage alarm .
The moment the power is restored, an undervoltage alarm is issued, while the motor remains in a coast-to-stop state.

Description
Trip after decelerate-to-stop
As soon as the DC link bus voltage drops below the continuous running level due to a momentary power failure, decelerate-to-shop control is invoked. Decelerate-to-stop control regenerates kinetic energy from the load's moment of inertia, slowing down the motor and continuing the deceleration operation. After decelerate-to-stop operation, an undervoltage alarm
is issued.
(Available in the ROM version 0500 or later.)
Enable restart (Restart at the frequency at which the power failure occurred, for general loads)
As soon as the DC link bus voltage drops below the undervoltage detection level due to a momentary power failure, the inverter saves the output frequency being applied at that time and shuts down the output so that the motor enters a coast-to-stop state.
If a run command has been input, restoring power restarts the inverter at the output frequency saved during the last power failure processing.
This setting is ideal for applications with a moment of inertia large enough not to slow down the motor quickly, such as fans, even after the motor enters a coast-to-stop state upon occurrence of a momentary power failure.
Enable restart (Restart at the starting frequency, for low-inertia load)
After a momentary power failure, restoring power and then entering a run command restarts the inverter at the starting frequency specified by function code F23.
This setting is ideal for heavy load applications such as pumps, having a small moment of inertia, in which the motor speed quickly goes down to zero as soon as it enters a coast-to-stop state upon occurrence of a momentary power failure.
If you enable the "Restart mode after momentary power failure" (Function code F14 = 4 or 5), the inverter automatically restarts the motor running when the power is restored. Design the machinery or equipment so that human safety is ensured after restarting.
Otherwise an accident could occur.
5-32
Restart mode after momentary power failure (Basic operation) The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below the undervoltage detection level, while the inverter is running. If the load of the motor is light and the duration of the momentary power failure is extremely short, the voltage drop may not be great enough for a momentary power failure to be recognized, and the motor may continue to run uninterrupted. Upon recognizing a momentary power failure, the inverter enters the restart mode (after a recovery from momentary power failure) and prepares for restart. When power is restored, the inverter goes through an initial charging stage and enters the ready-to-run state. When a momentary power failure occurs, the power supply voltage for external circuits such as relay sequence circuits may also drop so as to turn the run command OFF. In consideration of such a situation, the inverter waits 2 seconds for a run command input after the inverter enters a ready-to-run state. If a run command is received within 2 seconds, the inverter begins the restart processing in accordance with the F14 data (Mode selection). If no run command has been received within 2-second wait period, the inverter cancels the restart mode (after a recovery from momentary power failure) and needs to be started again from the ordinary starting frequency. Therefore, ensure that a run command is entered within 2 seconds after a recovery of power, or install a mechanical latch relay. When run commands are entered via the keypad, the above operation is also necessary for the mode (F02 = 0) in which the rotational direction is determined by the terminal command, FWD or REV. In the modes where the rotational direction is fixed (F02 = 2 or 3), it is retained inside the inverter so that the restart will begin as soon as the inverter enters the ready-to-run state.
If the "Coast to a stop" terminal command BX is entered during the power failure, the inverter gets out of the restart mode and enters the normal running mode. If a run command is entered with power supply applied, the inverter will start from the normal starting frequency (F23).
5-33
During a momentary power failure, the motor slows down. After power is restored, the inverter restarts at the frequency just before the momentary power failure. Then, the current limiting function works and the output frequency of the inverter automatically decreases. When the output frequency matches the motor speed, the motor accelerates up to the original output frequency. See the figure below. In this case, the instantaneous overcurrent limiting must be enabled (H12 = 1).
Restart mode after momentary power failure (Restart time) (H13)
H13 specifies the time period from momentary power failure occurrence until the inverter reacts for restarting process.
inrush current may flow or an overvoltage alarm may occur due to an occurrence of temporary regeneration. For safety, therefore, it is advisable to set H13 to a certain level so that restart will take place only after the residual voltage has dropped to a low level. Note that even when power is restored, restart will not take place until the restart time (H13) has elapsed.
Factory default
By factory default, H13 is set at one of the values shown below according to the inverter capacity. Basically, you do not need to change H13 data. However, if the long restart time causes the flow rate of the pump to overly decrease or causes any other problem, you might as well reduce the setting to about a half of the default value. In such a case, make sure that no alarm occurs.
Inverter capacity kW (HP) 0.1 to 7.5 (1/8 to 10) 11 to 15 (15 to 20)
Factory default of H13 (Restart time in seconds) 0.5 1.0
5-34
Restart mode after momentary power failure (Frequency fall rate) (H14)
During restart after a momentary power failure, if the inverter output frequency and the idling motor speed cannot be harmonized with each other, an overcurrent will flow, activating the overcurrent limiter. If it happens, the inverter reduces the output frequency to match the idling motor speed according to the reduction rate (Frequency fall rate: Hz/s) specified by H14.

0.01 to 100.00 (Hz/s)

Follow the selected deceleration time Follow data specified by H14 Follow the setting of the PI processor in the current limiter. (The PI constant is prefixed inside the inverter.)
If the frequency fall rate is too high, regeneration may take place at the moment the motor rotation matches the inverter output frequency, causing an overvoltage trip. On the contrary, if the frequency fall rate is too low, the time required for the output frequency to match the motor speed (duration of current limiting action) may be prolonged, triggering the inverter overload prevention control.
F15, F16 Frequency Limiter (High and Low)
H63
Low Limiter (Mode selection)
F15 and F16 specify the upper and lower limits of the output frequency, respectively.
H63 specifies the operation to be carried out when the output frequency drops below the low level specified by F16, as follows:
When H63 = 0, the output frequency will be held at the low level specified by F16. When H63 = 1, the inverter decelerates to stop the motor.
When you change the frequency limiter (High) (F15) in order to raise the reference frequency, be sure to change the maximum frequency (F03, A01) accordingly. Maintain the following relationship among the data for frequency control: F15 > F16, F15 > F23(A12), and F15 > F25 F03/A01 > F16 where, F23(A12) is of the starting frequency and F25 is of the stop frequency. If you specify any wrong data for these function codes, the inverter may not run the motor at the desired speed, or cannot start it normally.

Bias (Frequency command 1) Bias (for Frequency 1) (Bias base point) Analog Input Adjustment for [12] (Gain, Gain base point) Analog Input Adjustment [C1] (Gain, Gain base point)
When any analog input for frequency command 1 (F01) is used, it is possible to define the relationship between the analog input and the reference frequency by multiplying the gain and adding the bias specified by F18.
As shown in the graph below, the relationship between the analog input and the reference frequency specified by frequency command 1 is determined by points "A" and "B." Point "A" is defined by the combination of the bias (F18) and its base point (C50); Point "B," by the combination of the gain (C32, C37) and its base point (C34, C39).
The combination of C32 and C34 applies to terminal [12] and that of C37 and C39, to terminal [C1].
Configure the bias (F18) and gain (C32, C37), assuming the maximum frequency as 100%, and the bias base point (C50) and gain base point (C34, C39), assuming the full scale (10 VDC or 20 mA DC) of analog input as 100%.
The analog input less than the bias base point (C50) is limited by the bias value (F18).
Specifying that the data of the bias base point (C50) is equal to or greater than that of each gain base point (C34, C39) will be interpreted as invalid, so the inverter will reset the reference frequency to 0 Hz.
Example: Setting the bias, gain and their base points when the reference frequency 0 to 100% follows the analog input of 1 to 5 VDC to terminal [12] (in frequency command 1).
5-36
(Point A) To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is the bias base point and it is equal to 10% of 10 V (full scale), set the bias base point to 10% (C50 = 10).
(Point B) To make the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to 100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale), set the gain base point to 50% (C34 = 50).
The setting procedure for specifying a gain or bias alone without changing any base points is the same as that of Fuji conventional inverters.
F20 to F22 DC Braking 1 (Braking starting frequency, Braking level, and Braking time)
H95
DC Braking (Braking response mode)
F20 through F22 specify the DC braking that prevents motor 1 from running by inertia during decelerate-to-stop operation.
If the motor enters a decelerate-to-stop operation by turning OFF the run command or by decreasing the reference frequency below the stop frequency, the inverter activates the DC braking by flowing a current at the braking level (F21) during the braking time (F22) when the output frequency reaches the DC braking starting frequency (F20).
Setting the braking time (F22) to "0.00" disables the DC braking.
Braking starting frequency (F20)
F20 specifies the frequency at which the DC braking starts its operation during motor decelerate-to-stop state.
Generally, set the motor rated slip frequency or so to F20. Setting an extremely large value makes the control unstable; according to conditions, it activates an overvoltage protection.
Braking level (F21)
F21 specifies the output current level to be applied when the DC braking is activated. The function code data should be set, assuming the rated output current of the inverter as 100%, in increments of 1%.
For single-phase 100 V class series
The braking level setting (F21) should be calculated from the DC braking level IDB (A) based on the reference current Iref (A), as shown below.
Setting (%) = IDB (A) 100 I ref (A)
(Example) Setting the braking level IDB at 4.2 Amp (A) for 1 HP standard motors Setting (%) = 4.2 (A) 100 84 5.0 (A)

Characteristics
Slow response. Slows the rising edge of the current, thereby preventing reverse rotation at the start of DC braking.
Quick response. Quickens the rising edge of the current, thereby accelerating the build-up of the braking torque.
Note Insufficient braking torque may result at the start of DC braking.
Reverse rotation may result depending on the moment of inertia of the mechanical load and the coupling mechanism.
It is also possible to use an external digital input signal as an "Enable DC braking" terminal command DCBRK.
As long as the DCBRK command is ON, the inverter performs DC braking, regardless of the braking time specified by F22.
Turning the DCBRK command ON even when the inverter is in a stopped state activates DC braking. This feature allows the motor to be excited before starting, resulting in smoother acceleration (quicker build-up of acceleration torque).
In general, specify data of function code F20 at a value close to the rated slip frequency of motor. If you set it at an extremely high value, control may become unstable and an overvoltage alarm may result in some cases.
The DC brake function of the inverter does not provide any holding mechanism. Injuries could occur.

F23 F24 F25 F39
Starting Frequency 1 Starting Frequency 1 (Holding time) Stop Frequency Stop Frequency (Holding time)
At the startup of an inverter, the initial output frequency is equal to the starting frequency 1 specified by F23. The inverter stops its output when the output frequency reaches the stop frequency specified by F25.
Set the starting frequency to a level at which the motor can generate enough torque for startup. Generally, set the motor's rated slip frequency as the starting frequency.
In addition, to compensate for the delay time for the establishment of a magnetic flux in the motor, F24 specifies the holding time for the starting frequency. To stabilize the motor speed at the stop of the motor, F39 specifies the holding time for the stop frequency.
If the starting frequency is lower than the stop frequency, the inverter will not output any power as long as the reference frequency does not exceed the stop frequency.
5-39
F26, F27 Motor Sound (Carrier frequency and tone)
Motor sound (Carrier frequency) (F26) F26 controls the carrier frequency so as to reduce an audible noise generated by the motor or electromagnetic noise from the inverter itself, and to decrease a leakage current from the main output (secondary) wirings.
Carrier frequency Motor sound noise emission Motor temperature (due to harmonics components) Ripples in output current waveform Leakage current Electromagnetic noise emission Inverter loss
0.75 to 16 kHz High Low High Low Large Small Low High Low High Low High
Specifying a too low carrier frequency will cause the output current waveform to have a large amount of ripples. As a result, the motor loss increases, causing the motor temperature to rise. Furthermore, the large amount of ripples tends to cause a current limiting alarm. When the carrier frequency is set to 1 kHz or below, therefore, reduce the load so that the inverter output current comes to be 80% or less of the rated current.
When a high carrier frequency is specified, the temperature of the inverter may rise due to an ambient temperature rise or an increase of the load. If it happens, the inverter automatically decreases the carrier frequency to prevent the inverter overload alarm . With consideration for motor noise, the automatic reduction of carrier frequency can be disabled. Refer to the description of H98.
Motor sound (Tone) (F27)
F27 changes the motor running sound tone. This setting is effective when the carrier frequency set to function code F26 is 7 kHz or lower. Changing the tone level may reduce the high and harsh running noise from the motor.
If the sound level is set too high, the output current may become unstable, or mechanical vibration and noise may increase. Also, these function codes may not be very effective for certain types of motor.

For single-phase 100 V class series Outputting the output current to analog output terminal [FMA] as analog output voltage (F31 = 2) The analog output terminal [FMA] outputs 10 V, that is, 200% of the reference current Iref (A), supposing the output gain (specified by F30) as 100%. Therefore, to adjust the output voltage, you need to set the output gain at terminal [FMA] (F30) based on the conversion result obtained by the following expression:
Conversion formula for calculating the output gain which is required for outputting the voltage V (V) via terminal [FMA] when current I (A) flows across the inverter
Output gain = 2 Iref (A) V (V) 100 I (A) 10 (V) Iref (A): Reference current (A)
The reference current is given in the table for F20 to F22.

V/f control In this control, the inverter controls a motor by the voltage and frequency according to the V/f pattern specified by function codes.
Slip compensation Applying any load to an induction motor causes a rotational slip due to the motor
presumes the slip value of the motor based on the motor torque generated and raises the output frequency to compensate for the decrease in motor rotation. This prevents the motor from decreasing the rotation due to the slip. That is, this facility is effective for improving the motor speed control accuracy. The compensation value is specified by combination of function codes P12 (Rated slip frequency), P09 (Slip compensation gain for driving)) and P11 (Slip compensation gain for braking).
Dynamic torque vector control To get the maximal torque out of a motor, this control calculates the motor torque for the load applied and uses it to optimize the voltage and current vector output. Selecting this control automatically enables the auto torque boost and slip compensation function and disables auto energy saving operation. This control is effective for improving the system response against external disturbances and the motor speed control accuracy.
V/f control for PMSM drive Under this control, the inverter drives a permanent magnet synchronous motor (PMSM). Refer to Section 5.3 "Notes in Driving PMSM" for details.

F43, F44 Current Limiter (Mode selection, Level)
When the output current of the inverter exceeds the level specified by the current limiter (F44), the inverter automatically manages its output frequency to prevent a stall and limit the output current. (Refer to the description of function code H12.)
If F43 = 1, the current limiter is enabled only during constant speed operation. If F43 = 2, the current limiter is enabled during both of acceleration and constant speed operation. Choose F43 = 1 if you need to run the inverter at full capability during acceleration and to limit the output current during constant speed operation.
For single-phase 100 V class series The limiting level setting (F44) should be calculated from the current limiting level Ilimit (A) based on the reference current Iref (A), as shown below.
Setting (%) = I limit (A) 100 Iref (A)
(Example) Setting the current limiting level Ilimit at 4.2 A for 1 HP standard motors Setting (%) = 4.2 (A) 100 84 5.0 (A)

Level (F44)
F44 specifies the operation level at which the output current limiter becomes activated, in ratio to the inverter rating.
Since the current limit operation with F43 and F44 is performed by software, it may cause a delay in control. If you need a quick response, specify a current limit operation by hardware (H12 = 1) at the same time.
If an excessive load is applied when the current limiter operation level is set extremely low, the inverter will rapidly lower its output frequency. This may cause an overvoltage trip or dangerous turnover of the motor rotation due to undershooting.

F50, F51 Electronic Thermal Overload Protection for Braking Resistor
(Discharging capability and Allowable average loss)
A braking resistor can be mounted on inverters of 0.4 kW or above.
These function codes specify the electronic thermal overload protection feature for the braking resistor.
Set F50 and F51 data to the discharging capability and allowable average loss, respectively. Since those values differ depending on the specifications of the braking resistor, refer to the tables given below or calculate them according to the expressions given in the FRENIC-Mini User's Manual (24A7-E-0023), Chapter 9 "FUNCTION CODES."
Depending on the thermal marginal characteristics of the braking resistor, the
electronic thermal overload protection feature may act so that the inverter issues
the overheat protection alarm
even if the actual temperature rise is not
enough. If it happens, review the relationship between the performance index of the
braking resistor and settings of related function codes.
The tables below list the discharging capability and allowable average loss of the braking resistor. These values depend upon the inverter and braking resistor models.
External Braking Resistors
Standard models
The thermal sensor relay mounted on the braking resistor acts as a thermal protector of the motor for overheat, so assign an "Enable external alarm trip" terminal command THR to any of digital input terminals [X1] to [X3], [FWD] and [REV] and connect that terminal and its common terminal to braking resistor's terminals 2 and 1.
To protect the motor from overheat without using the thermal sensor relay mounted on the braking resistor, configure the electronic thermal overload protection facility by setting F50 and F51 data to the discharging capability and allowable average loss values listed below, respectively.

E01 to E03, Terminal [X1] to [X3] Function E98, E99 Terminal [FWD] and [REV] Function
Function codes E01 to E03, E98 and E99 allow you to assign commands to terminals [X1] to [X3], [FWD], and [REV] which are general-purpose, programmable, digital input terminals. These function codes may also switch the logic system between normal and negative to define how the inverter logic interprets either ON or OFF status of each terminal. The default setting is normal logic system "Active ON." So, explanations that follow are given in normal logic system "Active ON."
5-48
In the case of digital input, you can assign commands to the switching means for the run command and its operation and the reference frequency (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE). Be aware that switching any of such signals may cause a sudden start (running) or an abrupt change in speed.
An accident or physical injury may result.

Terminal function assignment and data setting
Select multistep frequency (0 to 15 steps) -- SS1, SS2, SS4, and SS8 (Function code data = 0, 1, 2, and 3)
The combination of the ON/OFF states of digital input signals SS1, SS2, SS4 and SS8 selects one of 16 different frequency commands defined beforehand by 15 function codes C05 to C19 (Multistep frequency 0 to 15). With this, the inverter can drive the motor at 16 different preset frequencies.
The table below lists the frequencies that can be obtained by the combination of switching SS1, SS2, SS4 and SS8. In the "Selected frequency" column, "Other than multistep frequency" represents the reference frequency sourced by frequency command 1 (F01), frequency command 2 (C30), or others.

Select ACC/DEC time -- RT1 (Function code data = 4)
This terminal command switches between ACC/DEC time 1 (F07, F08) and ACC/DEC time 2 (E10, E11).
If no RT1 command is assigned, ACC/DEC time 1 (F07, F08) takes effect by default.

Enable 3-wire operation -- HLD (Function code data = 6) Turning this terminal command ON self-holds the forward FWD or reverse REV run command issued with it, to enable 3-wire inverter operation. Short-circuiting the terminals between HLD and [CM] (i.e., when HLD is ON) self-holds the first FWD or REV command at its leading edge. Turning HLD OFF releases the self-holding. When HLD is not assigned, 2-wire operation involving only FWD and REV takes effect.
Coast to a stop -- BX (Function code data = 7) Turning this terminal command ON immediately shuts down the inverter output so that the motor coasts to a stop without issuing any alarms.
Reset alarm -- RST (Function code data = 8) Turning this terminal command ON clears the ALM state--alarm output (for any fault). Turning it OFF erases the alarm display and clears the alarm hold state. When you turn the RST command ON, keep it ON for 10 ms or more. This command should be kept OFF for the normal inverter operation.
Enable external alarm trip -- THR (Function code data = 9) Turning this terminal command OFF immediately shuts down the inverter output (so that the motor coasts to a stop), displays the alarm , and outputs the alarm relay (for any fault) ALM. The THR command is self-held, and is reset when an alarm reset takes place.
Use this alarm trip command from external equipment when you have to immediately shut down the inverter output in the event of an abnormal situation in a peripheral equipment.

Ready for jogging -- JOG (Function code data = 10)
This terminal command is used to jog or inch the motor for positioning a work piece. Turning this command ON makes the inverter ready for jogging. Simultaneous keying + keys on the keypad is functionally equivalent to this command; however, it is restricted by the run command source as listed below.
When the run command source is the keypad (F02 = 0, 2 or 3):
Input terminal command JOG

Jogging operation
Pressing the key or turning the FWD or REV terminal command ON starts jogging. For the jogging by the keypad, the inverter jogs only when the key is held down. Releasing the key decelerates to stop. During jogging, the frequency specified by C20 (Jogging Frequency) and the acceleration/deceleration time specified by H54 (ACC/DEC Time) apply.
operation" is possible only when the inverter is stopped.
To start jogging operation by simultaneously entering the JOG terminal command and a run command (e.g., FWD), the input delay time between the two commands should be within 100 ms. If a run command FWD is entered first, the inverter does not jog the motor but runs it ordinarily until the next input of the JOG.
Select frequency command 2/1 -- Hz2/Hz1 (Function code data = 11)
Turning this terminal command ON and OFF switches the frequency command source between frequency command 1 (F01) and frequency command 2 (C30). If no Hz2/Hz1 terminal command is assigned, the frequency sourced by F01 takes effect by default.

Upon completion of switching, the digital terminal output "Switched to motor 2" SWM2 (assigned to any of terminals [Y1] and [30A/B/C]) turns ON. If no M2/M1 terminal command is assigned, motor 1 is selected by default.

The UP/DOWN control is available in two modes--one mode (H61 = 0) in which the initial value of the reference frequency is fixed to "0.00" at the start of the UP/DOWN control and the other mode (H61 = 1) in which the reference frequency applied in the previous UP/DOWN control applies as the initial value.
When H61 = 0, the reference frequency applied by the previous UP/DOWN control has been cleared to "0," so at the next restart (including powering on), use the UP terminal command to accelerate the speed as needed.
When H61 = 1, the inverter internally holds the current output frequency set by the UP/DOWN control and applies the held frequency at the next restart (including powering on).
At the time of restart, if an UP or DOWN terminal command is entered before the internal frequency reaches the output frequency saved in the memory, the inverter saves the current output frequency into the memory and starts the UP/DOWN control with the new frequency. The previous frequency held will be overwritten by the current one.

When the frequency command source is switched to the UP/DOWN control from other sources, the initial frequency for the UP/DOWN control is as listed below:

Enable communications link via RS-485 -- LE (Function code data = 24) Turning this terminal command ON assigns priorities to frequency commands or run commands received via the RS-485 communications link (H30). No LE assignment is functionally equivalent to the LE being ON. (Refer to the description of H30.)
Run forward -- FWD (Function code data = 98) Turning this terminal command ON runs the motor in the forward direction; turning it OFF decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
Run reverse -- REV (Function code data = 99) Turning this terminal command ON runs the motor in the reverse direction; turning it OFF decelerates it to stop.
This terminal command can be assigned only by E98 or E99.
E20 E27
Terminal [Y1] Function Terminal [30A/B/C] Function (Relay output)
E20 and E27 assign output signals (listed on the next page) to general-purpose, programmable output terminals [Y1] and [30A/B/C]. These function codes can also switch the logic system between normal and negative to define the property of those output terminals so that the inverter logic can interpret either the ON or OFF status of each terminal as active. The factory default settings are "Active ON."
Terminal [Y1] is a transistor output and terminals [30A/B/C] are relay contact outputs. In normal logic, if an alarm occurs, the relay will be energized so that [30A] and [30C] will be closed, and [30B] and [30C] opened. In negative logic, the relay will be deenergized so that [30A] and [30C] will be opened, and [30B] and [30C] closed. This may be useful for the implementation of failsafe power systems.
When a negative logic is employed, all output signals are active (e.g. an alarm would be recognized) while the inverter is powered OFF. To avoid causing system malfunctions by this, interlock these signals to keep them ON using an external power supply. Furthermore, the validity of these output signals is not guaranteed for approximately 1.5 seconds after power-on, so introduce such a mechanism that masks them during the transient period.
Terminals [30A/B/C] use mechanical contacts that cannot stand frequent ON/OFF switching. Where frequent ON/OFF switching is anticipated (for example, limiting a current by using signals subjected to inverter output limit control such as switching to commercial power line), use transistor output [Y1] instead. The service life of a relay is approximately 200,000 times if it is switched ON and OFF at one-second intervals.

The table below lists functions that can be assigned to terminals [Y1] and [30A/B/C].

Inverter running -- RUN (Function code data = 0)
This output signal tells the external equipment that the inverter is running at a starting frequency or higher. It comes ON when the output frequency exceeds the starting frequency, and it goes OFF when it is less than the stop frequency. It is also OFF when the DC braking is in operation. If this signal is assigned in negative logic (Active OFF), it can be used as a signal indicating "Inverter being stopped."
Frequency arrival signal -- FAR (Function code data = 1)
This output signal comes ON when the difference between the output frequency and reference frequency comes within the frequency arrival hysteresis width specified by E30. (Refer to the description of E30.)
5-57
Frequency detected -- FDT (Function code data = 2)
This output signal comes ON when the output frequency exceeds the frequency detection level specified by E31, and it goes OFF when the output frequency drops below the "Frequency detection level (E31) - Hysteresis width (E32)."
Undervoltage detected -- LU (Function code data = 3)
This output signal comes ON when the DC link bus voltage of the inverter drops below the specified undervoltage level, and it goes OFF when the voltage exceeds the level. This signal is ON also when the undervoltage protective function is activated so that the motor is in an abnormal stop state (e.g., tripped). When this signal is ON, a run command is disabled if given.
Inverter output limiting -- IOL (Function code data = 5)
This output signal comes ON when the inverter is limiting the output frequency by activating any of the following actions (minimum width of the output signal: 100 ms).
Current limiting by software (F43 and F44) Instantaneous overcurrent limiting by hardware (H12 = 1) Automatic deceleration (Anti-regenerative control) (H69 = 2 or 4)
When the IOL signal is ON, the output frequency may have deviated from the specified frequency because of the limiting function above.
Auto-restarting after momentary power failure -- IPF (Function code data = 6)
This output signal is ON either during continuous running after a momentary power failure or during the period from when the inverter has detected an undervoltage condition and shut down the output until restart has been completed (the output has reached the reference frequency).
To enable this IPF signal, set F14 (Restart mode after momentary power failure) to "4" (Enable restart (Restart at the frequency at which the power failure occurred)) or "5" (Enable restart (Restart at the starting frequency)) beforehand.
Motor overload early warning -- OL (Function code data = 7)
This output signal is used to issue a motor overload early warning that enables you to take a
corrective action before the inverter detects a motor overload alarm
and shuts down its
output. (Refer to the description of E34.)
Service lifetime alarm -- LIFE (Function code data = 30)
This output signal comes ON when it is judged that the service life of any one of capacitors (DC link bus capacitors and electrolytic capacitors on the printed circuit board) and cooling fan has expired.
This signal should be used as a guide for replacement of the capacitors and cooling fan. If this signal comes ON, use the specified maintenance procedure to check the service life of these parts and determine whether the parts should be replaced or not.
For details about the judgment on service life, refer to Table 7.3 "Criteria for Issuing a Lifetime Alarm" in Chapter 7, Section 7.3 "List of Periodical Replacement Parts."
5-58
Inverter running 2 -- RUN2 (Function code data = 35) This signal acts in the same way as RUN (Function code data = 0) except that RUN2 is ON even when the DC braking is in operation.
Overload prevention control -- OLP (Function code data = 36) This output signal comes ON when the overload prevention control is activated. The minimum ON-duration is 100 ms. (Refer to the description of H70.)
Current detected and Current detected 2 -- ID and ID2 (Function code data = 37, 38) The ID or ID2 output signal comes ON when the output current of the inverter exceeds the level specified by E34 (Current detection (Level)) or E37 (Current detection 2 (Level)) for the time longer than the one specified by E35 (Current detection (Timer)) or E38 (Current detection 2 (Timer)), respectively. The minimum ON-duration is 100 ms. The ID or ID2 goes OFF when the output current drops below 90% of the rated operation level. These two output signals can be assigned to two different digital output terminals independently if necessary.
Function code E34 is effective for not only the motor overload early warning OL, but also for the operation level of the current detection ID. (Refer to the description of E34.)
Low current detected -- IDL (Function code data = 41) This output signal comes ON when the inverter output current drops below the low current detection level (E34) and it remains at the low level for the timer period (E35). When the output current exceeds the current detection level (E37) by 5% or more of the inverter rated current, this signal goes OFF. The minimum ON-duration is 100 ms. (Refer to the description of E34.)
Under PID control -- PID-CTL (Function code data = 43) This output signal comes ON when PID control is enabled ("Cancel PID control" (Hz/PID) = OFF) and a run command is ON. (Refer to the description of J01.)
Motor stopped due to slow flowrate under PID control -- PID-STP (Function code data = 44) This output signal comes ON when the inverter is stopped by the slow flowrate stop function under PID control. (Refer to the descriptions of J15 through J17.)
When PID control is enabled, the inverter may stop due to the slow flowrate stop function or other reasons, with the PID-CTL signal being ON. As long as the PID-CTL signal is ON, PID control is effective, so the inverter may abruptly resume its operation, depending on the PID feedback value.
When PID control is enabled, even if the inverter stops its output during operation because of sensor signals or other reasons, operation will resume automatically. Design your machinery so that safety is ensured even in such cases. Otherwise, an accident could occur.
5-59
Switched to motor 2 -- SWM2 (Function code data = 49) This output signal comes ON when motor 2 is selected with the M2/M1 terminal command assigned to a digital input terminal. For details, refer to the descriptions of E01 through E03 (Function code data = 12).
Motor overheat detected by thermistor (PTC) -- THM (Function code data = 56) When the thermistor is enabled (H26 = 2), this output signal comes ON if the motor temperature rises to the protection trigger level specified by H27.
Brake signal -- BRKS (Function code data = 57) This signal outputs a brake control command that releases or activates the brake.
Terminal [C1] wire break -- C1OFF (Function code data = 59) When terminal [C1] is used for a feedback signal under PID control, this output signal comes ON if the [C1] wire breaks, thereby enabling it to activate the protection function.
Frequency arrival detected -- FARFDT (Function code data = 87) The FARFDT, which is an ANDed signal of FAR and FDT, comes ON when both signal conditions are met.
Alarm output (for any alarm) -- ALM (Function code data = 99) This output signal comes ON if any of the protective functions is activated and the inverter enters Alarm mode.
E30
Frequency Arrival (Hysteresis width for FAR)
E30 specifies the detection level (hysteresis width) for FAR ("Frequency arrival signal"). The moment the output frequency reaches the zone defined by "Reference frequency Hysteresis width specified by E30," the FAR comes ON. The operation timings of signals are shown in the graph below.

Motor overload early warning signal -- OL
The OL signal is used to detect a symptom of an overload condition (alarm code
) of the
motor so that the user can take an appropriate action before the alarm actually happens.
The OL signal turns ON when the inverter output current has exceeded the level specified by E34. In typical cases, set E34 data to 80 to 90% against F11 data (Electronic thermal overload protection for motor 1, Overload detection level). Specify also the thermal characteristics of the motor with F10 (Select motor characteristics) and F12 (Thermal time constant). To utilize this feature, you need to assign OL (data = 7) to any of the digital output terminals.
Current detected and Current detected 2 signals -- ID and ID2
When the inverter output current has exceeded the level specified by E34 or E37 and it continues longer than the period specified by E35 or E38, the ID or ID2 signal turns ON, respectively. When the output current drops below 90% of the rated operation level, the ID or ID2 turns OFF. (Minimum width of the output signal: 100 ms)
To utilize this feature, you need to assign ID (data = 37) or ID2 (data = 38) to any of digital output terminals.
5-61
Low current detected -- IDL
This signal turns ON when the output current drops below the low current detection level (E34) and remains at the low level for the timer period (E35). When the output current exceeds the "Low current detection level plus 5% of the inverter rated current," it goes OFF. (The minimum ON-duration is 100 ms.)

Coefficient for Constant Feeding Rate Time Coefficient for Speed Indication
E39 and E50 specify coefficients for determining the constant feeding rate time, load shaft speed, and line speed, as well as for displaying the output status monitored.
Calculation expression Coefficient for speed indication (E50)
Constant feeding rate time (min) = Frequency × Coefficient for constant feeding rate time (E39)
Load shaft speed = Coefficient for speed indication (E50) × Frequency (Hz) Line speed = Coefficient for speed indication (E50) × Frequency (Hz)
Where, the "frequency" refers to the "reference frequency" to be applied for settings (constant feeding rate time, load shaft speed, or line speed), or to the "output frequency before slip compensation" to be applied for monitor.
If the constant feeding rate time is 999.9 min. or more or the denominator of the right-hand side is zero (0), "999.9" appears.

Description
--
This is an auxiliary analog frequency input to be added to frequency command 1 (F01). It is never added to frequency command 2, multistep frequency command or other frequency commands.
This is an auxiliary analog frequency input to be added to all frequency commands including frequency command 1, frequency command 2 and multistep frequency commands.
This input includes temperature, pressure or other commands to apply under the PID control. Function code J02 should be also configured.
This input includes the feedback of the temperature or pressure under the PID control. (Not available for E60.)
If the built-in potentiometer and different terminals have been set up to have the same data, the operation priority is given in the following order:
E60 > E61 > E62
Selecting the UP/DOWN control (F01, C30 = 7) ignores auxiliary frequency command 1 and 2.

C21
Timer Operation
C21 enables or disables a timer operation that is triggered by a run command and continues for the timer count previously specified with the / keys. The operating procedure for the timer operation is given below.
Data for C21 0 1
Function Disable timer operation Enable timer operation
Pressing the key during timer countdown quits the timer operation.
Even if C21 = 1, setting the timer to 0 no longer starts the timer operation with the key.
Applying terminal command FWD or REV instead of the key command can also start the timer operation.
Operating procedure for timer operation (example)
Preparation
To display the timer count on the LED monitor, set E43 (LED Monitor) to "13" (Timer) and set C21 (Timer Operation) to "1" (Enable).
Specify the reference frequency to apply to timer operation. When the keypad is selected as a frequency command source, press the key to shift to the speed monitor and specify the desired reference frequency.
Triggering the timer operation with the key
(1) While watching the timer count displayed on the LED monitor, press the / key to set the timer for the desired count in seconds. Note that the timer count on the LED monitor appears as an integral number without a decimal point.
(2) Press the key. The motor starts running and the timer starts counting down. If the timer counts down, the motor stops without pressing the key. (Even if the LED monitor displays any item except the timer count, the timer operation is possible.)
After the countdown of the timer operation triggered by a terminal command such
as FWD, the inverter decelerates to stop and at that moment the LED monitor
displays
and any LED monitor item ( for the timer count) alternately. Turning
FWD OFF returns to the LED monitor item.
C33 C38
Analog Input Adjustment for Terminal [12] (Filter time constant) Analog Input Adjustment for Terminal [C1] (Filter time constant)
C33 and C38 configure a filter time constant for an analog voltage and current input on terminals [12] and [C1], respectively.
The larger the time constant, the slower the response. Specify the proper filter time constant taking into account the response speed of the machine (load). If the input voltage fluctuates due to line noise, remove the cause of the noise or take an electric circuit related measure. Only when no effect is obtained, increase the time constant.

Motor 1 (Auto-tuning)
The inverter automatically detects the motor parameters and saves them in its internal memory. Basically, it is not necessary to perform tuning when using a Fuji standard motor with a standard connection with the inverter.
In any of the following cases, perform auto-tuning since the motor parameters are different from those of Fuji standard motors so as not to obtain the best performance under each of these controls-- auto torque boost, torque calculation monitoring, auto energy saving operation, automatic deceleration (anti-regenerative control), slip compensation, and torque vector control.
The motor to be driven is made by other manufacturer or is a non-standard motor. Cabling between the motor and the inverter is long. A reactor is inserted between the motor and the inverter.
For details of auto-tuning, refer to Chapter 4, Section 4.1.3 "Preparation before a test run--Configuring function code data."
P06, P07 P08, P12
Motor 1 (No-load current, %R1, %X and Motor 1, Rated slip frequency)
P06 through P08 and P12 specify no-load current, %R1, %X, and rated slip frequency, respectively. Obtain the appropriate values from the test report of the motor or by calling the manufacturer of the motor.
Performing auto-tuning automatically sets these parameters.
No-load current (P06): Enter the value obtained from the motor manufacturer.
%R1 (P07):
Enter the value calculated by the following expression.
R1+ CableR1
%R1=

V / ( 3 ×I)
where,
X1: Primary leakage reactance of the motor ( )
X2: Secondary leakage reactance of the motor (converted to primary) ( )
XM: Exciting reactance of the motor ( )
Cable X: Reactance of the output cable ( )
V: Rated voltage of the motor (V)
I: Rated current of the motor (A)
Rated slip frequency (P12)
Convert the value obtained from the motor manufacturer to Hz using the following expression and enter the converted value. (Note: The motor rating given on the nameplate sometimes shows a larger value.)
Rated slip frequency (Hz) =
(Synchronous speed - Rated speed) Synchronous speed
x Base frequency
For reactance, choose the value at the base frequency 1 (F04).
P09
P10 P11
Motor 1 (Slip compensation gain for driving) (Slip compensation response time) (Slip compensation gain for braking)
P09 and P11 determine the slip compensation amount in % for driving and braking individually. Specification of 100% fully compensates for the rated slip of the motor. Excessive compensation (P09, P11 100%) may cause a system oscillation, so carefully check the operation on the actual machine.
P10 determines the response time for slip compensation. Basically, there is no need to modify the default setting. If you need to modify it, consult your Fuji Electric representatives.

Automatic control (such as auto torque boost and auto energy saving) or electronic thermal overload protection for motor uses the motor parameters and characteristics. To match the property of a control system with that of the motor, select characteristics of the motor and set H03 data (Data Initialization) to "2" to initialize the motor parameters stored in the inverter. The initialization automatically updates the P03 and P06 to P12 data and the constants used inside the inverter.
According to the motor model, set the P99 data as shown below.
For Fuji standard IM, 8-series (Current standard induction motors), P99 = 0 For Fuji standard IM, 6-series (Conventional standard induction motors), P99 = 3 For other manufacturers' IM or model-unknown IM, P99 =4 For PMSM, P99 = 20 or 21 (to be selected after consultation with motor manufacturers)
When P99 = 4, the inverter runs following the motor characteristics of Fuji standard IM, 8-series.
When P99 = 1, the inverter applies to the characteristics of HP rating IM (Typical in North America).

Initialize all function code data to the factory defaults
Initialize motor 1 parameters in accordance with P02 (Rated capacity) and P99 (Motor 1 selection) Function codes subject to initialization: P03, P06 to P12 and constants for internal control (These function codes will be initialized to the values listed in tables on the following pages.)
Initialize motor 2 parameters in accordance with A16 (Rated capacity) and A39 (Motor 2 selection) Function codes subject to initialization: A17, A20 to A26 and constants for internal control (These function codes will be initialized to the values listed in tables on the following pages.)
To initialize the motor parameters, set the related function codes using the following steps.
1) P02/A16
Set the rated capacity of the motor to be used in kW.
Motor (Rated capacity)
2) P99/A39 Motor Selection
Select the characteristics of the motor.
3) H03 Data Initialization Initialize the motor parameters. (H03 = 2 or 3)
4) P03/A17 Motor (Rated current)
Set the rated current on the nameplate if the already set data differs from the rated current printed on the nameplate of the motor.
Upon completion of the initialization, the H03 data reverts to "0" (factory default).
If the P02 or A16 data is set to a value other than the nominal applied motor rating, data initialization with H03 internally converts the specified value forcedly to the equivalent nominal applied motor rating (see the tables on the next page).
When a PMSM is selected (P99 = 20 or 21), initializing motor parameters by setting the H03 data to "2" reverts function code data for both IM and PMSM to factory defaults.

H04, H05 Auto-reset (Times and Reset interval)
H04 and H05 specify the auto-reset function that makes the inverter automatically attempt to reset the tripped state and restart without issuing an alarm (for any faults) even if any protective function subject to reset is activated and the inverter enters the forced-to-stop state (tripped state).
If the protective function works in excess of the times specified by H04, the inverter will issue an alarm (for any faults) and not attempt to auto-reset the tripped state.
Listed below are the recoverable alarm statuses to be retried.

Number of reset times (H04)
H04 specifies the number of reset times for the inverter to automatically attempt to escape from the tripped state. When H04 = 0, the auto-reset function will not be activated.
If the "auto-reset" function has been specified, the inverter may automatically restart and run the motor stopped due to a trip fault, depending on the cause of the tripping. Design the machinery so that human body and peripheral equipment safety is ensured even when the auto-resetting succeeds. Otherwise an accident could occur.
Reset interval (H05) After the reset interval specified by H05 from when the inverter enters the tripped state, it issues a reset command to auto-reset the tripped state. Refer to the timing scheme diagram below. <Timing scheme for failed retry (No. of reset times: 3)>
The auto-reset operation can be monitored from the external equipment by assigning the digital output signal TRY to any of the programmable output terminals [Y1] and [30A/B/C] with E20 or E27 (data = 26).
5-74
H06
Cooling Fan ON/OFF Control
To prolong the life of the cooling fan and reduce fan noise during running, the cooling fan stops when the temperature inside the inverter drops below a certain level while the inverter stops. However, since frequent switching of the cooling fan shortens its life, the cooling fan is kept running for 10 minutes once it is started.
H06 specifies whether to keep running the cooling fan all the time or to control its ON/OFF.
Data for H06 0 1
Cooling fan ON/OFF Disable (Cooling fan always ON) Enable (ON/OFF control effective)
H07
Acceleration/Deceleration Pattern
H07 specifies the acceleration and deceleration patterns (patterns to control output frequency).
Linear acceleration/deceleration The inverter runs the motor with the constant acceleration and deceleration.
S-curve acceleration/deceleration
To reduce an impact that acceleration/deceleration would make on the machine (load), the inverter gradually accelerates or decelerates the motor in both starting and ending zones of acceleration/deceleration. Two types of S-curve acceleration/deceleration rates are available; 5% (weak) and 10% (strong) of the maximum frequency, which are shared by the four inflection points.
The acceleration/deceleration time command determines the duration of acceleration/ deceleration in the linear period; hence, the actual acceleration/deceleration time is longer than the reference acceleration/deceleration time.
5-75
Acceleration/deceleration time <S-curve acceleration/deceleration (weak): when the frequency change is 10% or more of the maximum frequency> Acceleration or deceleration time (s) = (2 x 5/100 + 90/100+ 2 x 5/100) x (reference
acceleration or deceleration time) = 1.1 x (reference acceleration or deceleration time)
<S-curve acceleration/deceleration (strong): when the frequency change is 20% or more of the maximum frequency> Acceleration or deceleration time (s) = (2 x 10/100 + 80/100 + 2 x 10/100) x (reference
acceleration or deceleration time) = 1.2 x (reference acceleration or deceleration time)
Curvilinear acceleration/deceleration Acceleration/deceleration is linear below the base frequency (constant torque) but it slows down above the base frequency to maintain a certain level of load factor (constant output). This acceleration/deceleration pattern allows the motor to accelerate or decelerate with the maximum performance of the motor.
Choose an appropriate acceleration/deceleration time, taking into account the ma
H11
Deceleration Mode
H11 specifies the deceleration mode to be applied when a run command is turned OFF.
Data for H11 0
1
Function
Normal deceleration The inverter decelerates and stops the motor according to deceleration commands specified by H07 (Acceleration/deceleration pattern), F08 (Deceleration time 1), and E11 (Deceleration time 2).
Coast-to-stop The inverter immediately shuts down its output, so the motor stops according to the inertia of the motor and machine and their kinetic energy losses.
When reducing the reference frequency, the inverter decelerates the motor according to the deceleration commands even if H11 = 1 (Coast-to-stop).
5-76
H12
Instantaneous Overcurrent Limiting (Mode selection)
H12 specifies whether the inverter invokes the current limit processing or enters the overcurrent trip when its output current exceeds the instantaneous overcurrent limiting level. Under the current limit processing, the inverter immediately turns OFF its output gate to suppress the further current increase and continues to control the output frequency.
Data for H12 0 1
Function
Disable An overcurrent trip occurs at the instantaneous overcurrent limiting level.
Enable The current limiting operation is effective.
If any problem occurs when the motor torque temporarily drops during current limiting processing, it is necessary to cause an overcurrent trip (H12 = 0) and actuate a mechanical brake at the same time.
The similar function is the current limiter specified by F43 and F44. The current limiter (F43, F44) implements the current control by software, so an operation delay occurs. When you have enabled the current limiter (F43, F44), also enable the instantaneous overcurrent limiting with H12 to obtain a quick response current limiting.
Depending on the load, extremely short acceleration time may activate the current limiting to suppress the increase of the inverter output frequency, causing hunting (undesirable oscillation of the system) or activating the inverter overvoltage trip (alarm ). When specifying the acceleration time, therefore, you need to take into account machinery characteristics and moment of inertia of the load.
When the instantaneous overcurrent limiting is enabled, the motor output torque could drop. For driving elevating machinery which could cause a serious problem with a drop of the motor output torque, therefore, disable the instantaneous overcurrent limiting. Note that disabling it will cause an overcurrent trip when a current exceeding the inverter protection level flows, so secure the protective coordination using a mechanical brake. An accident could occur.
5-77
H45 H97
Mock Alarm Clear Alarm Data
H45 causes the inverter to generate a mock alarm in order to check whether external sequences function correctly at the time of machine setup.
Setting the H45 data to "1" displays mock alarm
on the LED monitor. It also issues alarm
output ALM (if assigned to a digital output terminal specified by E20 or E27). (Accessing the
H45 data requires simultaneous keying of " key + key.") After that, the H45 data
automatically reverts to "0," allowing you to reset the alarm.
Just as for data (alarm history and relevant information) of those alarms that could occur in running the inverter, the inverter saves mock alarm data, enabling you to confirm the mock alarm status.
To clear the mock alarm data, use H97. (Accessing the H97 data requires simultaneous keying of " key + key.") H97 data automatically reverts to "0" after clearing the alarm data.
H69 H76
Automatic Deceleration (Anti-regenerative control) (Mode selection) Automatic Deceleration (Frequency increment limit for braking)
H69 specifies the anti-regenerative control.
In inverters not equipped with a PWM converter or braking resistor, if regenerative energy returned exceeds the inverter's braking capability, an overvoltage trip occurs.
When H69 = 1: The anti-regenerative control is functionally equivalent to that of the original
FRENIC-Mini series (FRN
C1 - ). That is, when the DC link bus voltage exceeds
the preset voltage limiting level, the inverter lengthens the deceleration time to three times
the specified time to decrease the deceleration torque to 1/3. In this way, the inverter
reduces the regenerative energy tentatively. This control applies only in deceleration. When
the load on the motor results in a braking effect, the control does not have any effect.
When H69 = 2 or 4: The inverter controls the output frequency to keep the braking torque at around 0 N·m in both acceleration/deceleration and constant speed running phases in order to avoid an overvoltage trip.
Since increasing the output frequency too much under anti-regenerative control is dangerous, the inverter has a torque limiter (Frequency increment limit for braking) that can be specified by H76. The torque limiter limits the inverter's output frequency to less than "Reference frequency + H76 setting."
Note that the torque limiter activated restrains the anti-regenerative control, resulting in a trip with an overvoltage alarm in some cases. Increasing the H76 data (0.0 to 400.0 Hz) makes the anti-regenerative control capability high.
In addition, during deceleration triggered by turning the run command OFF, the anti-regenerative control increases the output frequency so that the inverter may not stop the load depending on the load state (huge moment of inertia, for example). To avoid that, H69 provides a choice of cancellation of the anti-regenerative control to apply when three times the specified deceleration time is elapsed, thus decelerating the motor.

Enabling the anti-regenerative control may automatically increase the deceleration time.
When a braking resistor is connected, disable the anti-regenerative control.
H70
Overload Prevention Control
H70 specifies the decelerating rate of the output frequency to prevent a trip from occurring
due to an overload. This control decreases the output frequency of the inverter before the
inverter trips due to a heat sink overheat or inverter overload (with an alarm indication of
or
, respectively). It is useful for equipment such as pumps where a decrease in the
output frequency leads to a decrease in the load and it is necessary to keep the motor running
even when the output frequency drops.

In equipment where a decrease in the output frequency does not lead to a decrease in the load, the overload prevention control is of no use and should not be enabled.
H71
Deceleration Characteristics
Setting the H71 data to "1" (ON) enables forced brake control. If regenerative energy pro braking capability, an overvoltage trip will occur. The forced brake control increases the motor energy loss during deceleration, increasing the deceleration torque.
This function is aimed at controlling the torque during deceleration; it has no effect if there is braking load.
Enabling the automatic deceleration (anti-regenerative control, H69 = 2 or 4) disables the deceleration characteristics specified by H71.
When replacing the original FRENIC-Mini series (FRN

H94
Cumulative Run Time of Motor 1
Operating the keypad can display the cumulative run time of motor 1. This feature is useful for management and maintenance of the machinery. Using H94 can modify the cumulative run time of the motor to the desired value to be used as an arbitrary initial data. Specifying "0" clears the cumulative run time.
H98
Protection/Maintenance Function (Mode selection)
H98 specifies whether to enable or disable (a) automatic lowering of carrier frequency, (b) input phase loss protection, (c) output phase loss protection, and (d) judgment on the life of the DC link bus capacitor, as well as specifying the judgment threshold on the life of the DC link bus capacitor, in a combination of Bit 0 to Bit 4.
Automatic lowering of carrier frequency (Bit 0)
This function should be used for important machinery that requires keeping the inverter running.
Even if a heat sink overheat or overload occurs due to excessive load, abnormal ambient
temperature, or cooling system failure, enabling this function lowers the carrier frequency to
avoid tripping (
or
). Note that enabling this function results in increased motor
noise.
Input phase loss protection (
) (Bit 1)
Upon detection of an excessive stress inflicted on the apparatus connected to the main circuit
due to phase loss or line-to-line voltage unbalance in the three-phase power supplied to the
inverter, this feature stops the inverter and displays an alarm
.
In configurations where only a light load is driven or a DC reactor is connected, phase loss or line-to-line voltage unbalance may not be detected because of the relatively small stress on the apparatus connected to the main circuit.
Output phase loss protection ( ) (Bit 2) Upon detection of phase loss in the output while the inverter is running, this feature stops the inverter and displays an alarm . Where a magnetic contactor is installed in the inverter output circuit, if the magnetic contactor goes OFF during operation, all the phases will be lost. In such a case, this protection feature does not work.
Judgment threshold on the life of DC link bus capacitor (Bit 3) Bit 3 is used to select the threshold for judging the life of the DC link bus capacitor between factory default setting and your own choice.
Before specifying the threshold of your own choice, measure and confirm the reference level in advance. For details, refer to Chapter 7.
5-80
Judgment on the life of DC link bus capacitor (Bit 4)
Whether the DC link bus capacitor has reached its life is determined by measuring the length of time for discharging after power OFF. The discharging time is determined by the capacitance of the DC link bus capacitor and the load inside the inverter. Therefore, if the load inside the inverter fluctuates significantly, the discharging time cannot be accurately measured, and as a result, it may be mistakenly determined that the life has been reached. To avoid such an error, you can disable the judgment on the life of the DC link bus capacitor.
Since load may vary significantly in the following cases, disable the judgment on the life during operation. Either conduct the measurement with the judgment enabled under appropriate conditions during periodical maintenance or conduct the measurement under the operating conditions matching the actual ones.
A remote keypad (option) is used. Another inverter or equipment such as a PWM converter is connected to the terminals of the DC link bus.
For details, refer to Chapter 7.

When driving a permanent magnet synchronous motor (PMSM), observe the following notes. Items not covered in this section are the same as for induction motor (IM) drive.
The PMSM drive is available in the ROM version 0500 or later. (The ROM version can be checked
with item

Specifications
A PMSM cannot be driven by commercial power. Be sure to use an inverter. A failure could occur.
Be sure to match inverter's output terminals (U, V and W) with motor's input terminals (U, V and W).
When F42 = 11 (V/f control for PMSM drive) At the start of driving the motor, the inverter flows current equivalent to 80% of the motor rated current (P03) to pull in the magnetic pole position for synchronization. After that, the inverter accelerates the motor to the reference frequency. No magnetic pole position detection function is provided. No auto search for an idling PMSM and restart function are provided. Depending upon the magnetic pole position, the motor may run in the reverse direction slightly at the start of running.
The speed control range is from 10% to 100% of the base frequency (F04). Set the reference frequency to 10% or more of the F04 data.
The following motor parameters are used, so consult the motor manufacturer and configure the correct values. No tuning function is provided. F03: Maximum Frequency 1 (Hz) F04: Base frequency (Hz) F05: Rated voltage at base frequency) (V)
(When F05 = 0, the inverter acts as 200/400V setting.) F06: Maximum Output Voltage 1 (V) P03: Motor rated current (A) P60: Armature resistance ( ) P61: d-axis inductance (mH) P62: q-axis inductance (mH) P63: Induced voltage (V) P90: Overcurrent protection level (A) If any of P60, P62 and P63 is set to "0.00," the inverter does not start. Be sure to set correct values. The factory defaults of P60 to P63 are "0.00." If motor parameters are not correct, the inverter cannot run normally. Set P90 to the value less than the demagnetizing current. A failure could occur.
The carrier frequency (F26) should be 2 to 16 kHz. Running a PMSM at 0.75 or 1 kHz may result in a failure due to demagnetization. The automatic carrier frequency lowering function at the time of inverter overheat does not work. A failure could occur.
A PMSM cannot be driven as the 2nd motor.

Specifications
Linear V/f pattern only. The load selection value (F37) will be ignored. When driving a PMSM, the high-efficiency control is always ON. A PMSM cannot be tuned. Not available for a PMSM. The H12 setting will be ignored. Even if H12 = 1, an overcurrent trip occurs due to an overcurrent incident.
When the F14 data is set to either 4 or 5, the inverter restarts with pull-in by current.
When H69 = 1, the automatic deceleration is performed only on inverters
compatible with the original FRENIC-Mini series (FRN
C1 - ).
When H69 = 2 or 4, no automatic deceleration is performed.
Not available for a PMSM. It is always OFF. Not available for a PMSM. Not available for a PMSM.
Be sure to consult the motor manufacturers before actual operation. A failure could occur.
