Cause : Earth leakage - comes when drive has detected load unbalance typically due to earth fault in motor or motor cable.
- Check there are no power factor correction capacitors or surge absorbers in motor cable.
- Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable.
- Try running the motor in scalar control mode if allowed. (See parameter 99.04 Motor control mode.)
