14-3* Current Limit Control
The adjustable frequency drive features an integral current limit controller which is activated when the motor
current, and thus the torque, is higher than the torque limits set in par.4-16
4-17 Torque Limit Generator
When the current limit is reached during motor operation or regenerative operation, the adjustable frequency
drive will try to reduce torque below the preset torque limits as quickly as possible without losing control of the
motor.
While the current control is active, the adjustable frequency drive can only be stopped by setting a digital input

fied in this parameter, the adjustable frequency drive trips. Disable the
trip delay by setting the parameter to 60 s = OFF. Thermal adjustable

Function:
When the adjustable frequency drive detects an overvoltage in the set
time, tripping will be affected after the set time.
