Code Modbus ID Parameter Application RO/RW
P6.4.6 326 OverCurrent Attempts 1,2,3 RW
This parameter determines the number of allowed restart-attempts after “Overcurrent” condition has
occurred.
Note: An IGBT temperature fault, Saturation Fault and Overcurrent Faults are included as part of this fault.
0 = No automatic restart after overcurrent fault trip
>0 = Number of automatic restarts after an overcurrent trip, saturation trip or IGBT temperature fault.
P6.4.7 327 4mA Fault Attempts 1,2,3 RW
This parameter determines the number of allowed restart-attempts after “4-20mA fault” condition has
occurred.
0 = No automatic restart after reference fault trip
>0 = Number of automatic restarts after the analog current signal (4–20 mA) has returned to the normal
level (>4 mA)
P6.4.8 329 Motor Temp Fault Attempts 1,2,3 RW
This parameter determines the number of allowed restart-attempts after “Thermistorfault Motor” condition
has occurred.
0 = No automatic restart after Motor temperature fault trip
>0 = Number of automatic restarts after the motor temperature has returned to its normal level
P6.4.9 328 External Fault Attempts 1,2,3 RW
This parameter determines the number of allowed restart-attempts after “External Fault” condition has
occurred.
0 = No automatic restart after External fault trip
>0 = Number of automatic restarts after External fault trip
P6.4.10 336 Underload Attempts 1,2,3 RW
This parameter determines the number of allowed restart-attempts after “Underload Motor” condition has
occurred.
0 = No automatic restart after an Underload fault trip
>0 = Number of automatic restarts after an Underload fault trip
P6.4.11 2803 OP Cont Interlock Attempts 1,2,3 RW
This determines the number of auto restart attempts that will occur on an output contactor interlock fault.
P7.1.1 1294 PID1 Control Gain 2,3 RW
This parameter is used to defines the proportional gain of the PID Controller. It adjust the slope of the speed
increase according to the initial of the load. If this value is set to 100% a change of 10% in the error value
causes the controller output to change 10%.
P7.1.2 1295 PID1 Control ITime 2,3 RW
This parameter is used to defines the integration time constant of the PID Controller. Over the time the
integral time contributes to the deviation between the reference and the feedback signal. If this value is set
to 1.00 sec, a change of 10% in the error value causes the controller output to change by 10.00%/s. With
value set to 0.0, frequency converter operates as PD controller.
P7.1.3 1296 PID1 Control DTime 2,3 RW
This parameter is used to defines the derivation time constant of the PID Controller. This value will adjust the
rate of change on the feedback signal. If this value is set to 1.00 sec, a change of %10 in error value during
1.00 sec causes the control output to change by %10.00. If value is set to 0.0, frequency converter operates
as PI controller.
P7.1.4 1297 PID1 Process Unit 2,3 RW
This parameter is used to defines the unit type for PID controller. This will change the Feedback and Setpoint
variables to show the desired unit of measure.
P7.1.5 1298 PID1 Process Unit Min 2,3 RW
This parameter is used to defines the minimum process unit value for the PID controller.
P7.1.6 1300 PID1 Process Unit Max 2,3 RW
This parameter is used to defines the maximum process unit value for the PID controller.
P7.1.7 1302 PID1 Process Unit Decimal 2,3 RW
This parameter is used to defines the amount of decimal places used in the value for the
PID Controller setpoint.
P7.1.8 1303 PID1 Error Inversion 2,3 RW
This parameter defines the way the process value output reacts to the feedback signal.
0 = Normal, If feedback is less than set-point, PID controller output increases.
1 = Inverted, If feedback is less than set-point, PID controller output decreases.
