Analysis, Types, and Maintenance Solutions for Delta Inverter GFF Fault

I. Meaning and Internal Mechanism of Delta Inverter GFF Fault

When a Delta inverter reports a “GFF” fault code, it indicates a “Ground Fault” (GFF) has occurred at the output terminal. This fault typically involves issues with the output circuit, such as damage to the IGBT, a short circuit in the output, or problems with the driver circuit, particularly when using PC929 optocouplers.

Physical picture of Delta INVERTER MS300 series

II. Analysis of the GFF Fault Scenario Described

In the scenario provided, the Delta inverter reports a GFF fault immediately upon connecting the motor, but the fault disappears when the motor wires are disconnected and the inverter is started alone. This suggests that the issue lies with the motor or the connection between the motor and the inverter, rather than the inverter itself.

Possible Causes:

  1. Motor Wiring Issues:
    • Short circuit or ground fault in the motor wiring.
    • Poor connection or loose wires at the motor terminals.
  2. Motor Problems:
    • Internal short circuit or ground fault within the motor.
    • Insulation failure or damage in the motor windings.
  3. External Interference:
    • Electromagnetic interference from nearby equipment affecting the inverter’s output circuit.
  4. IGBT or Driver Circuit Damage:
    • Although less likely in this case (since the fault disappears without the motor), damage to the IGBT or driver circuit could still be a factor if there are underlying issues with the inverter’s output stage.
