GENERAL This application is aimed to be used in the Vacon liquid-cooled AC drive inside the Heat exchanger unit. The idea with the application is to maintain a constant flow of coolant through the heat exchanger and through the Vacon liquid-cooled drive. The user sets a certain speed for the pump of the heat exchanger unit that produces a sufficient flow through the Vacon liquid-cooled drives to keep them cooled. This speed is NOT regulated but fixed by a parameter set value. The Vacon AC drive also handles the temperature of the water in the heat exchanger unit by regulating the valve that handles the coolant intake to the heat exchanger element (from the customer's system). This regulation is based on the temperature of the water in the pipes between the outlet of the heat exchanger pump and the inlet of the cooling element of the Vacon liquid-cooled drive. The actual value of the temperature for the regulation comes from a sensor called FSA11. This is a type of flow switch that measures both the temperature of the coolant and the flow in the pipes. If there is not enough flow in the pipe the sensor gives a signal that tells the drive to stop due to insufficient flow. Vacon NX AC drives can be connected to the Profibus DP using a fieldbus board. The AC drive can then be controlled, monitored and programmed from the Host system. Profibus fieldbus board (OPT-C5) is normally included in the delivery of Vacon NX liquid-cooled drive Heat Exchanger Solution. The Profibus fieldbus board must be installed in slot E on the control board of the AC drive. For more information on the Profibus fieldbus board, see Vacon OPTC3/C5 Profibus Option Board User Manual. The standard delivery also includes I/O boards OPT-A1 (placed in slot A), OPT-A2 (placed in slot B) and OPT-B5 (placed in slot C or D). The application, however, offers you more signals than the standard set of I/O boards allows you to connect. If you wish to use one additional analogue input signal and/or two additional analogue output signals, we recommend you to order Vacon I/O board OPT-B4 and place it in the last free board slot (C or D).

DESCRIPTION OF PARAMETERS On the following pages you will find the parameter descriptions arranged according to the individual ID number of the parameter. A shaded parameter ID number (e.g. 418 Motor potentiometer UP) indicates that the TTF programming method is applied to this parameter (see All-in-One Application Manual). Some parameter names are followed by a number code indicating the "All in One" applications in which the parameter is included. If no code is shown the parameter is available in all applications. See below. The parameter numbers under which the parameter appears in different applications are also given. 101 Minimum frequency 102 Maximum frequency (2.1.1) (2.1.2) Defines the frequency limits of the AC drive. The maximum value for these parameters is 320 Hz. The software will automatically check the values of parameters ID105, ID106 and ID728. 103 Acceleration time 1 104 Deceleration time 1 (2.1.3) (2.1.4) These limits correspond to the time required for the output frequency to accelerate from the zero frequency to the set maximum frequency (par. ID102). 105 Preset speed 1 (2.1.15) Parameter values are automatically limited between the minimum and maximum frequencies (par. ID101, ID102). 107 Current limit (2.1.5) This parameter determines the maximum motor current from the AC drive. The parameter value range differs from size to size. When this parameter is changed the stall current limit (ID710) is internally calculated to 90% of current limit. 108 U/f ratio selection (2.6.2) Linear: 0 Squared: 1 The voltage of the motor changes linearly with the frequency in the constant flux area from 0 Hz to the field weakening point where the nominal voltage is supplied to the motor. Linear U/f ration should be used in constant torque applications. Use this default setting if there is no special need for another setting. The voltage of the motor changes following a squared curve form with the frequency in the area from 0 Hz to the field weakening point where the nominal voltage is also supplied to the motor. The motor runs undermagnetised below the field weakening point and produces less torque and electromechanical noise. Squared U/f ratio can be used in applications where torque demand of the load is proportional to the square of the speed, e.g. in centrifugal fans and pumps. 24-hour support: +358 (0)201 212 575 · Email: vacon@vacon.com 4 22 · vacon U[V] Un ID603 Default: Nominal voltage of the motor Description of parameters Field weakening point Linear Squared Default: Nominal frequency of the motor f[Hz] NX12K07 Figure 1. Linear and squared change of motor voltage Programmable U/f curve: 2 The U/f curve can be programmed with three different points. Programmable U/f curve can be used if the other settings do not satisfy the needs of the application. Un ID603 U[V] Default: Nominal voltage of the motor Field weakening point ID605 (Def. 10%) ID606 (Def. 1.3%) Default: Nominal frequency of the motor f[Hz] ID604 (Def. 5 Hz) ID602 NX12K08 Figure 2. Programmable U/f curve Linear with flux optimisation: 3 The AC drive starts to search for the minimum motor current in order to save energy, lower the disturbance level and the noise. This function can be used in applications with constant motor load, such as fans, pumps etc. 109 U/f optimisation (2.1.13) Automatic torque boost The voltage to the motor changes automatically which makes the motor produce sufficient torque to start and run at low frequencies. The voltage increase depends on the motor type and power. Automatic torque boost can be used in applications where starting torque due to starting friction is high, e.g. in conveyors.

First set the motor nominal values (Parameter group 2.1). Option 1: Activate the Automatic torque boost. Option 2: Programmable U/f curve To get torque you need to set the zero point voltage and midpoint voltage/frequency (in parameter group 2.6) so that the motor takes enough current at low frequencies. First set par. ID108 to Programmable U/f curve (value 2). Increase zero point voltage (ID606) to get enough current at zero speed. Set then the midpoint voltage (ID605) to 1.4142*ID606 and midpoint frequency (ID604) to value ID606/100%*ID111. NOTE! In high torque low speed applications it is likely that the motor will overheat. If the motor has to run a prolonged time under these conditions, special attention must be paid to cooling the motor. Use external cooling for the motor if the temperature tends to rise too high. 110 Nominal voltage of motor (2.1.6) Find this value Un on the rating plate of the motor. This parameter sets the voltage at the field weakening point (ID603) to 100% * UnMotor. Note also used connection Delta/Star. 111 Nominal frequency of motor (2.1.7) Find this value fn on the rating plate of the motor. This parameter sets the field weakening point (ID602) to the same value. 112 Nominal speed of motor (2.1.8) Find this value nn on the rating plate of the motor. 113 Nominal current of motor (2.1.9) Find this value In on the rating plate of the motor. 115 Parameter conceal With this parameter you can hide all other parameter groups except the basic parameter group (P2.1). Note! The factory default of this parameter is 1, i.e. all parameter groups except P2.1 are hidden. The other parameter groups cannot be browsed or edited before the value of this parameter is set to 0. 0 = Disabled (all parameter groups can be browsed with the keypad) 1 = Enabled (only the basic parameters, P2.1, can be browsed with the keypad) 24-hour support: +358 (0)201 212 575 · Email: vacon@vacon.com 4 24 · vacon Description of parameters 117 I/O frequency reference selection (2.1.14) Defines which frequency reference source is selected when controlled from the I/O control place. 0 = Keypad reference (Menu M3) 1 = Fieldbus reference 118 PID controller gain (2.9.4) This parameter defines the gain of the PID controller. If the value of the parameter is set to 100% a change of 10% in the error value causes the controller output to change by 10%. If the parameter value is set to 0 the PID controller operates as ID-controller. See examples at parameter ID132 below. 119 PID controller I-time (2.9.5) The parameter ID119 defines the integration time of the PID controller. If this parameter is set to 1.00 second a change of 10% in the error value causes the controller output to change by 10.00%/s. If the parameter value is set to 0.00 s the PID controller will operate as PD controller. See examples at parameter ID132 below. 120 Motor cos phi (2.1.10) Find this value "cos phi" on the rating plate of the motor. 121 Keypad frequency reference selection (2.2.22) Defines which frequency reference source is selected when controlled from the keypad. 0 Reference from keypad (Freq Ref) 1 Reference from fieldbus 122 Fieldbus frequency reference selection (2.2.23) Defines which frequency reference source is selected when controlled from the fieldbus. 0 Reference from keypad (Freq Ref) 1 Reference from fieldbus 132 PID controller D-time (2.9.6) The parameter ID132 defines the derivation time of the PID controller. If this parameter is set to 1.00 second a change of 10% in the error value during 1.00 s causes the controller output to change by 10.00%. If the parameter value is set to 0.00 s the PID controller will operate as PI controller. See examples below.

Once the difference between the setpoint and the process value has been reduced to 0 the output is reduced by the amount corresponding to the value of parameter 2.1.13. In case the error value is negative, the AC drive reacts reducing the output correspondingly.

Unlike DC braking, the motor speed remains controlled during braking.

Use Dead band parameter to define dead band area around the PID setpoint value (temperature setpoint). The output of the PID controller will be locked, if the actual temperature (measured temperature) stays in the dead band area for the set time. Use Dead band delay parameter to set the time that the actual temperature must stay in the dead band area, before the output of the PID controller is locked. The output of the PID controller will be released, if the actual temperature goes outside of the dead band area. Note! This function is disabled when Dead Band = 0. 24-hour support: +358 (0)201 212 575 · Email: vacon@vacon.com 4 52 · vacon Description of parameters 4.1 Keypad control parameters Unlike the parameters listed above, these parameters are located in the M3 menu of the control keypad.
