CE fault in INVT GD10 drive indicates a Communication Error. This means that the drive is unable to communicate with an external device, such as a PLC, HMI, or another drive, through the specified communication protocol (e.g., RS485, CANopen, Modbus RTU).

Common Causes of CE Faults:

  1. Incorrect Communication Settings:

    • Mismatched baud rate, parity, or stop bits between the drive and the external device.
    • Incorrectly configured communication address or node ID.
  2. Faulty Communication Cable:

    • Damaged or loose cable connections.
    • Incorrect cable shielding or grounding.
  3. Hardware Malfunction:

    • Faulty communication port or chip on the drive.
    • Damaged communication interface on the external device.
  4. Network Issues:

    • Network congestion or latency.
    • Network connectivity problems.

Troubleshooting Steps:

  1. Verify Communication Settings:

    • Double-check the baud rate, parity, stop bits, and address settings on both the drive and the external device.
    • Ensure that the communication protocol is correctly configured.
  2. Inspect Cable and Connections:

    • Visually inspect the communication cable for any damage or loose connections.
    • Check the cable shielding and grounding.
    • Try replacing the cable with a known good one.
  3. Test Communication Ports:

    • Use a multimeter to check for continuity and voltage levels on the communication port pins.
    • If possible, try connecting the drive to a different external device or communication port.
  4. Check Network Connectivity:

    • Verify the network connectivity between the drive and the external device.
    • Check for any network errors or conflicts.
