Cause : Earth leakage comes when drive has detected load unbalance typically due to earth fault in motor or motor cable.

The 2330 fault code in your ABB ACS560 drive indicates an earth leakage fault. This signifies a potential issue with current leakage to ground within the motor or motor cable.

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.
3. Try running the motor in scalar control mode if allowed. (See parameter 99.04 Motor control mode.)
4. If no earth fault can be detected then hardware issue in drive.
