Output Current Limit (Menu Index 2.7)

7.3.5
P 2.7.1 Output Current Limit %
Enter the current limit for motor and generator operation. The parameter is changed automatically if P 4.2.2.3 Nominal Motor Current is
updated.
Default value:
Size Related
Parameter
418
number:
Data type:
uint16
This is a true current limit function that continues in the oversynchronous range. However, due to field weakening, the motor torque at
current limit drops accordingly when the voltage increase stops above the synchronized motor speed.
P 2.7.2 Current Limit K
p
Enter the proportional gain for the current limit controller. Selecting a higher value makes the controller react faster but may reduce
stability.
Default value:
100
Parameter
1430
number:
Data type:
uint16
P 2.7.3 Current Limit T
i
Enter the integration time for the current limit controller. Selecting a lower value makes the controller react faster but may reduce
stability.
Default value:
0.02
Parameter
1431
number:
Data type:
uint16
P 2.7.4 Current Lim Ctrl, Filter Time
Enter the filter time period for the low-pass filter of the current limit control. The filter uses the average value over the period. Setting a
shorter period makes the control react faster to changes in current.
Default value:
5
Parameter
1432
number:
118
