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:
-
Incorrect Communication Settings:
- Mismatched baud rate, parity, or stop bits between the drive and the external device.
- Incorrectly configured communication address or node ID.
-
Faulty Communication Cable:
- Damaged or loose cable connections.
- Incorrect cable shielding or grounding.
-
Hardware Malfunction:
- Faulty communication port or chip on the drive.
- Damaged communication interface on the external device.
-
Network Issues:
- Network congestion or latency.
- Network connectivity problems.
Troubleshooting Steps:
-
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.
-
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.
-
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.
-
Check Network Connectivity:
- Verify the network connectivity between the drive and the external device.
- Check for any network errors or conflicts.
