Cause : Earth leakage - comes when drive has detected load unbalance typically due to earth fault in motor or motor cable. Follow these steps to correct fault :
1. Check there are no power factor correction capacitors or surge absorbers in motor cable.
2. Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable.
