GdP fault Emotron VSB Drive indicates Output ground short-circuit protection. This means a short circuit to ground has been detected on the output side of the drive or the motor.
Possible Causes:
1: Output connection ground short circuit.
2: Motor insulation abnormal.
3: Inverter module abnormal.
4: Output ground leakage current is too big.
Solutions:
1: Check motor connection and output ground impedance.
2: Check the motor.
