Cause : High Current Alarm comes when the output current has exceeded the overcurrent alarm level (over 150% of the rated current).

1. The load is too heavy or the accel/ decel time is too short. Increase the acceleration/deceleration time.
2. Either a specialized motor or an excessively large motor is being used. Verify the setting for the Inverter capacity.
3. The current has risen too high while performing speed search either during a momentary loss in power or during a fault restart
4. Momentary losses in power or fault restarts may occasionally trigger an overcurrent alarm, and are not necessarily indicators of an overcurrent problem.
