Cause : Current limit comes when the output current is greater than the value in parameter 221 Current Limit LIM, and the frequency converter will trip after a set time, selected in parameter 409 Trip delay overcurrent.
- If the motor torque limit is exceeded during ramp up, extend the ramp up time.
- If the generator torque limit is exceeded during ramp down, extend the ramp down time.
- If torque limit occurs while running, possibly increase the torque limit.
- Be sure the system can operate safely at a higher torque.
- Check the application for excessive current draw on the motor.
