I just replaced this drive as the old one went out when the plant had a power surge/flicker.
1-Installed the drive
2-Powered up
3- Got an immediate EARTH FAULT, so I check the manual and it talks about wires being grounded.
4- Disconnected wires from the motor and ohm out the wires to ground( CHECKS GOOD)
5-So I ohmed out the motor and I was getting 40-50 ohms when tested to ground.
6-I have not powered up the drive with out the wires disconnected. I will try that next to confirm my thoughts that the motor windings are starting to go bad and current is leaking out.
Bad motor?
