What to do if gefran ADP200 Inverter shows Overcurrent [OC] alarm?
If your Gefran Inverter displays an instantaneous overcurrent protection intervention alarm, this might be due to incorrect current regulator parameter settings. To resolve this: - Check the current regulator parameters (menu 17). - Check the wiring towards the motor.
