Introduction

LonWorks technology is made by Echelon Corp. and LonWorks Network is often used in factory or building automation. In LonWorks Network, Master/Slave concept doesn’t exist and all nodes (Device) of the Network communicate each other by LonTalk protocol. And LonWorks Nodes are independent not depending on the other manufacturing companies. This independency is possible by using Standard Network Variable Type (SNVT) offered by LonWorks and iS7 LonWorks comm. card also use Standard Network Variable Type. All Network variables are categorized into input and output variables and if the connection is made between input variable and output variable at first by Installation Tool, data communication can be done automatically. When input variable and output variable are connected, be sure to make the same Network variable Type.

Technical Features of LonWorks

Installation Guideline

When you install iS7 LonWorks Comm. card, refer to Quick Guide below.

1. Take away the packing material of iS7 LonWorks Comm. card and check if iS7 LonWorks Comm. card doesn’t get damaged apparently.
2. Feed power to iS7 and check if the functions of iS7 are operated correctly. Conducting Keypad operation, check the inverter operation.
3. After turning off the power of iS7, wait at least 10 minutes until the charged voltage of inverter will be discharged. Measuring DC Link voltage, make sure it can reach to safe voltage level.
4. Install LonWorks comm. card to iS7 inverter.
   ✓ Removing the cover of iS7 inverter, install iS7 LonWorks comm. card.
   Connect Comm. Cable (A, B). As there is no polarity in LonWorks Comm. Cable, you can connect without considering polarity.
   ✓ If present Node is connected to the last of the Network, using terminating resistance setting switch, conduct terminating setting.
5. For the Configuration of LonWorks Comm. card, download External Interface file iS7 LON.XIF) and Resource file from http://www.lselectric.co.kr
6. After feeding power to inverter, using iS7 Keypad, check if CNF-30 Option-1 Type is set automatically as LonWorks.
7. Conduct LonWorks comm. related parameter setting.
8. Examine LED state of iS7 LonWorks comm. card. If the Configuration isn’t done before, SERVICE LED is flicked as 0.5Hz.
9. After turning off the power of iS7 inverter, wait at least 10 minutes until DC Link voltage is discharged. As the installation of iS7 LonWorks comm. card, close the cover of inverter.
10. After feeding power to iS7 inverter once again, using Network Tool, conduct Configuration.
    Refer) For communicating with inverter through LonWorks first time, you have to do Configuration at least once. If iS7 LonWorks comm. card is installed in iS7 inverter and Configuration isn’t conducted, LonWorks comm. can’t be done.
11. For Configuration, make SVC switch OFF after making ON. Refer) When you do Configuration of LonWorks comm. card for the first time at Lon NetWokr using LonMaker, as Configuration Time of the LonMaker itself is long, Communication between inverter and communication card can’t be done during that Time, Option-1 Trip can happen. In   this case, after Configuration is completed, push RESTET button of Keypad for removing Option-1 Trip.
12. If Configuration in completed successfully, Service LED has to be Off. Refer) For commissioning of binding using LonMaker, they have to be performed at Network Process of Neuron Chip. In this case, Network Process is done at Neuron Chip, during that time communication interruption happens between inverter and LonWorks comm. card and Option-1 Trip occurs. At this time, push the RESET button of Keypad for removing Option-1 Trip.

Network Connection

iS7 LonWorks Comm. card offers Pluggable connector. Table below explains connector. LonWorks Comm. cable can be connected to connector number 1 and 2. AS LonWorks Comm. doesn’t have the polarity, you can connect cable without considering polarity.

Network Termination

Set up the terminal to guarantee the reliability of communication data.
You may set up the terminal of communication cards at both ends (BUS Topology) or a communication card at one side (Free Topology).
SV-iS7 LonWorks communication card contains a terminal resistance. You may determines whether you will use a terminal resistance by DIP switch in the SV-iS7 LonWorks communication card. Set up one or two terminal resistance according to network topology. Free topology uses 50 Ohm resistance and there is one LonWorks device that is terminated with a resistance in the network. In case of Bus topology, it has 100 Ohm as a terminal resistance and two LonWorks devices. This table describes terminated types according to the location of the switch.

8.2.1 Network Input Variables

1. nviDrvSpeedStpt
2. nviDrvSpeedScale

▲ Definition
Network input SNVT_switch nviDrvSpeedStpt
Network input SNVT_lev_percent nviDrvSpeedScale
▲ Description
nviDrvSpeedStpt and nviDrvSpeedScale are used for the inverter run and speed command. The state variable of nviDrvSpeedStpt is a value that decides the command to whether run or stop the inverter. If the state of nviDrvSpeedStpt is 0, the inverter will stop and the inverter will sun when the state value is 1. nviDrvSpeedScale offers information of the operative direction. If a value of the nviDrvSpeedScale is positive, the motor runs clockwise and if the nviDrvSpeedScale is negative, the motor runs counterclockwise.
Frequency command consists of a combination of nviDrvSpeedScale and nviDrvSpeedStpt. nviDrvSpeedScale and nviDrvSpeedStpt are in % units and the multiplied value of the two is the input for the frequency command of Base Freq. nviDrvSpeedScale provides the scale information of nviDrvSpeedStpt value. For example, if nviDrvSpeedStpt is 100%, nviDrvSpeedScale is -80%. The actual speed is -80% (1 x 0.8 = 0.8), Therefore inverter runs counterclockwise at a speed of Base frequency times 0.8. So, If base frequency is 60.00 Hz, the frequency command value would be 48 Hz (60.00 Hz X 0.8). The input range of nviDrvSpeedScale is -163.840% ~ 163.835%. The resolution of nviDrvSpeedScale is 0.005%. If a value more than +163.84% or lower than -163.845% is put in, this value would be a invalid data.
*Caution: If Run command is put in while a combination of nviDrvSpeedScale and nviDrvSpeedStpt is more than nciMaxSpeed, Run command may be not operate. In this case, put in the combination value of nviDrvSpeedScale and nviDrvSpeedStpt lower than nciMaxSpeed.
▲ Variable information of state of NviDrvSpeedStpt and value

When you want to do the run commands or frequency command with LonWorks, you should set up the DRV-06 Cmd source of PAR mode to ‘FieldBus’ and DRV-07 Freq Fef Src of PAR mode to ‘FieldBus’ by using keypad.

▲ Description
nvoDrvSpeed outputs the inverter’s current operation speed by the percentage value of the base frequency. When the inverter runs clockwise (counterclockwise), the value of nvoDrvSpeed gets a positive (negative) value. For example, if the base frequency is 60.00Hz and the inverter is running counterclockwise with 30.00Hz, nvoDrvSpeed output the value of -50.00%. Typical Range -163.835 ~ 163.835 % (0.005 %)

   Network config input SNVT_str_asc nciLocation
   ▲ Description
   nciLocation uses 6 bytes Location string of Neuron Chip and saves the information of physical location into nciLocation.
   Default Empty spaces
2. Maximum Motor Speed (Mandatory)
   ▲ Definition
   Network config input SNVT_lev_percent  nciMaxSpeed
   ▲ Description
   nciMaxSpeed is the value to set the max. speed of the motor. nciMaxSpeed is inputted by the percentage of the nominal frequency (nciNmlFreq) configuration value. For example, if nciNmlFreq 60.00 Hz and nciMaxSpeed is 120%, the max. frequency will be converted from % unit to Hz unit and 72.0 Hz (60.0 x 1.2). The value, 72.00 Hz, is written in the DRV-20 Max Freq and it will be shown on the keypad.  nciMaxSpeed value is not able to modify while the inverter runs. You should stop the inverter first then you can modify the nciMaxSpeed.
   The initial value of the nciMaxSpeed is the percentage value, which compares to the Base Freq. of DRV-18 and Max. Freq. of DRV-20. Therefore, the initial value of the nciMaxSpeed will be 100.00 %. nciMaxSpeed must satisfy the formula below.  0 ≤ Minimum Speed ≤ Maximum Speed ≤ 163.835   Typical Range 100.000 ~ 150.000 % (0.005%) Default  100.000%
   ※ As shown above, DRV-20 Max Freq is changed by nciMaxSpeed (% value) of nciNmlFreq. Since 40 ~ 400.00 Hz is setting range of Max. Freq., original setting range is preserved when  nciNmlFreq has to change below 40 Hz (ex. nciNmlFreq 30Hz, nciMaxSpeed 100.00 %).

   ▲ Inverter parameter of nciMaxSpeed

   Code Number/ Common Area Address	Code Description	Initial Value	Setting Range
   DRV-18	Base Freq	60.00 Hz	30.00 ~ 400.00
   DRV-20	Max Freq	60.00 Hz	40.00 ~ 400.00

   Minimum Motor Speed (Mandatory)
   ▲ Definition Network config input SNVT_lev_percent nciMinSpeed
   ▲ Description nciMinSpeed is the value to set the min. speed of the motor. nciMinSpeed is inputted by the percentage of the nominal frequency (nciNmlFreq) configuration value . For example, nicNmlFreq is 60.0 Hz and nicMinSpeed is 10%, the maximum frequency will be 6.0 Hz (60.0 x 0.1). The value, 6.00 Hz, is written in the DRV-19 Start Freq. and it will be shown on the keypad. nciMinSpeed value is not able to modify while the inverter runs. You should stop the inverter first and then modify the nciMinSpeed value. The initial value of nciMinSpeed is the percentage value of the Base Freq. of DRV-18 and Start Freq. of DRV-19. Therefore, the initial value of the nciMinSpeed will be 0.83%. nciMinSpeed must satisfy the formula below.  0 ≤ Minimum Speed ≤ Maximum Speed ≤ 163.835 Typical Range 0.000 ~ 40.000 % (0.005 %) Default 0.830%

Receive Heart Beat Time (Optional)
▲ Definition
Network config input SNVT_time_sec nciRcvHrtBt
▲ Description
Decide the maximum update cycle time of the network input variables, nviDrvSpeedStpt and nviDrvSpdScale. If update of of nviDrvSpeedStpt and nviDrvSpdScale does not occur during the (nciRcvHrtBt + PRT-13 Lost Cmd Time) time, it recognizes it as a condition of the communication command loss and starts to run as the mode in the communication command loss of PRT-12 Lost Cmd Mode.
If you want to run with mode which is set in the communication command loss, you have to set the DRV-06 Cmd Source to ‘Fieldbus’ or the DRV-07 Freq Ref Src to ‘Fieldbus’ as a value, not the value ‘0.0 sec’ of nciRcvHrtBt. Furthermore, PRT 12 Lost Cmd Mode has to be set the value, not ‘None’.
If the value of nciRcvHrtBt is to be set 0.0 sec, the function of communication command loss will be disable.
Typical Range 0.0 ~ 120.0 sec (0.1 sec)
Invalid data, when input value 0xFFFF (6553.6 sec)
Default 0.0 sec (not using Receive Heart Beat function)
▲ Inverter parameter nciRcvHrtBt

Caution) When communicating with LonWorks, communication command loss time of the inverter, (nciRcvHrtBt +PRT-13 Lost Cmd Time) will be applied. If the value of nciRcvHrtBt is to be set 0.0 sec, the function of communication command loss will be disable.

Typical Range 0.0 ~ 6553.5 sec (0.1 sec)
Invalid data, when input value is 0xFFFF (6553.6 sec)
Default 0.0 sec (not using Minimum Out Time function)
Nominal Motor Speed in RPM (Mandatory)
▲ Definition
Network config input SNVT_freq_hz nciNmlSpeed
▲ Description
nciNmlSpeed sets up the Base freq. of inverter.
The initial value of nciNmlSpeed will become 1800.00 rpm because it is converted from DRV18 Base
Freq into rpm (Base on 60 Hz of the Base Freq and 4 pole number). When the nciNmlSpeed value is modified, the value of nciNmlSpeed, which is converted from rpm into Hz is reflected in DRV-18 Base Freq.
The below is the formula to convert RPM into Hz. The inverter parameter, BAS-11 Pole
Number, means the pole number of the motor. You should set it properly.

Valid Range 0 ~ 65535 rpm (1 rpm)
Default 1800 rpm
▲ Inverter parameter of nciNmlSpeed

▲ Caution
nciNmlFreq is automatically changed when you modify nciNmlSpeed. For example, when nciNmlSpeed is 1800 rpm, nciNmlFreq is 60.00 Hz, BAS-11 Pole Number is 4, and if you change nciNmlFreq to 1700 rpm, then nciNmlFreq will be 56.7 Hz (DRV-18 Base Frequency is rounded up) and DRV-18 Base Frequency of keypad will be 56.66 Hz. DRV-19 Start Frequency and DRV-20 Max Frequency will be changed together when you modify nciNmlSpeed and nicNmlFreq. Referring to the above to the above example, if nciMaxSpeed is 100.00 % and nciMinSpeed 10.000%, DRV-19 Start Frequency will be 5.67 Hz and DRV-20 Max Frequency will be 56.66 Hz.
Nominal Motor Frequency (Mandatory)
▲ Definition
Network config input SNVT_freq_hz nciNmlFreq
▲ Description
nciNmlFreq sets up the Base Freq of inverter. The nciNmlFreq is an indispensable value to set the minimum (nicMinSpeed) and maximum (nciMaxSpeed) frequency of the motor. (nciMinSpeed and nciMaxSpeed are percentage values of the nciNmlFreq.) The initial value of nciNmlFreq is 60.00Hz, which is same as DRV-18 Base Freq.

Valid Range -163.840~ +163.835 (0.005 %)
Default 0.000 %
Cf.)
DRV-18 Base Freq, DRV-19 Start Freq, DRV-20 Max Freq, BAS-11 Pole Num, DRV-03 Acc Time, and DRV-04 Dec Time are keypad parameter that are closely related to the configuration property variable of Drive Object, such as nciNmlFreq, nciNmlSpeed, nciMaxSpeed, nciMinSpeed, nciRampUPTm, and nciRampDownTm.
To modify DRV-18 Base Freq, DRV-19 Start Freq, DRV-20 Max Freq, BAS-11 Pole Num, DRV-03 Acc Time, and DRV-04 Dec Time by keypad and save them into the configuration property variable, such as nciNmlFreq, nciNmlSpeed, nciMaxSpeed, nciMinSpeed, nciRampUPTm, and nciRampDownTm, turn off the inverter and turn it on again or you have to set COM-94 Comm Update to ‘Yes’.
For example, if you changes the keypad parameters as the table below, nciMaxSpeed is 150.000%, nciMinSpeed is 8.555%, nciNmlSpeed is 1370rpm, nciNmlFreq is 45.7Hz, nciRampUpTm is 19.0 sec, and nciRampDownTm is 29.0 sec.

① nciNmlFreq is down to the first decimal place and DRV-18 is down to the second decimal point place. Therefore, nciNmlFreq is 45.7, because it rounds off at the second decimal place of DRV-18.

All the Base Freq used in the calculation uses DRV-18 Base Freq.
The Max Freq value should not exceed 163.840 % of the Base Freq. The Maximum value of nciMaxSpeed is 163.840%.
Max. value of nciMaxSpeed is 163.835%. Cf.) When motor runs to positive direction (in case of Base Freq is 60Hz), nviDrvSpeedScale is 100% and nviDrvSpeedStpt is 100% as 1, the nciDrvSpeedScale will be changed to 50% therefore nviDrvSpeedScale will be changed to 50% (when monitoring) and motor still runs to positive direction with 60Hz. To apply the changed value, the value of nciDrvSpeedScale will be applied to 50% after writing the value of nviDrvSpeedScale or stop and then run the motor. The motor runs to the positive direction with 30 Hz.

8.3.1 Network Input Variables

(1) nviUsrParaCtrl1 ~ nviUsrParaCtrl8
▲ Definition
Network input SNVT_count nviUsrParaCtrl1 (identical until nviUsrParaCtrl8)
▲ Description
nviUsrParaCtrl1 ~ nviUsrParaCtrl8 are added network input variables to provide the LS inverter user with more flexible functions.
The strength of the function is the ability for the user to change the inverter parameter that the user actually wants to change and not the fixed parameter value of the inverter.
When the user puts in the address in parameter COM51 ~ 58 using the keypad, it corresponds one to one to the network variable nviUsrParaCtrl1 ~ nviUsrParaCtrl8 and could change the set up parameter value.
For example, if the user sets COM51 as 0x0005 (freq. setting), COM52 as 0x0006 (Operation command setting) and COM53 as 0x0007 (accelerating time), the user could set the frequency setting through nviUsrParaCtrl1, set the operation command through nviUsrParaCtrl2 and change the accelerating speed through nviUsrParaCtrl3. If you want to make the inverter run counterclockwise at a speed of 60.00 Hz with an accelerating time of 10.00 sec., put in 6000 for nviUsrParaCtrl1, 0x0004 for nviUsrParaCtrl2 and 100 for nviUsrParaCtrl3.

Network output SNVT_count nvoUsrParaState1 (identical until nvoUsrParaState8)
▲ Description
nvoUsrParaState1 ~ nvoUsrParaState8 are added network variables to provide the LS inverter user with more flexible functions. The strength of this function is the ability for the user to change the inverter parameter that the user actually wants to monitor and monitor the value of it. Not the fixed parameter value of the inverter.
When the user puts in the address in parameter COM31 ~ COM38 using the eypad, it corresponds one to one to the network variable nvoUsrParaState1 ~ nvoUsrParaState8 and the inverter’s parameter value gets displayed.
For example, if the user sets COM31 as 0x000A (Output Freq.), COM32 as 0x000B (Inverter Output Voltage) and COM33 as 0x941E (Jog Freq.), the variable nvoUsrParaState1 will display the Output Freq value, the variable nvoUsrParaState2 will display the Inverter Output Voltage and nvoUsrParaState3 will display the Jog Freq. If the inverter runs at a speed of 30.00 Hz, the DC link voltage is 150.0V and if the Jog Freq. is set to 20.00, then would be the value for nviUsrParaState1 is 3000, nviUsrParaState2 is 1500, and nviUsrParaState3 is 2000.

If you want to use the communication command loss, you have to set the DRV-06 or DRV07 as a ‘FieldBus’, not ‘0.0 sec’ of nciUsrPcvHrtBt. Furthermore, the RRT-12 command lost mode has to be set as a value also.
If the value of nciUsrRcvHrtBt is ‘0.0 sec’, communication command loss function is disabled.
Typical Range 0.0 ~ 120.0 sec (0.1 sec)
Invalid data, when input value is 0xFFFF (6553.6 sec)
Default 0.0 sec (not using Receive Heart Beat function)
▲ Inverter parameter of nciUsrRcvHrtBt

Caution) When communicating with LonWorks, communication command loss time of inverter, (nciUsrRcvHrtBt +PRT-13 Lost Cmd Time) value does gets applied. If the value of nciUsrRcvHrBt is 0.0 sec, communication command loss function is disabled.
(2) Send Heart Beat Time for User Object (Mandatory)
▲ Definition
Network config input SNVT_time_sec nciUsrSndHrtBt
▲ Description
It decides maximum output time of the User Object network output variable, User Object nvoUsrParaState1 ~ nvoUsrParaState8.
Typical Range 0.0 ~ 6553.5 sec
Invalid data, when input value is 0xFFFF (6553.6 sec).
Default 0.0 sec (not using Send Heart Beat function)
(3) Minimum Out Time for User Object (Mandatory)
▲ Definition
Network config input SNVT_time_sec nciUsrMinOUtTm
▲ Description
It decides the minimum time that the User Object network variable, nvoUsrParaState1 ~ nvoUsrParaState8 has to wait until it gets sent through communication.
The network value does not changed by every little variable but it sends out the changed nci UsrMinOutTm time. It is used to reduce network traffic.
Typical Range 0.0 ~ 6553.5 sec (0.1 sec)
Invalid data, when input value is 0xFFFF (6553.6 sec)
Default 0.0 sec (not using Minimum Out Time function)
