CE / CE10 Communication Error fault in delta drive

CE / CE10 Communication Error fault in delta drive troubleshooting

Description

CE faults relate to Modbus RS-485 or fieldbus communications. The drive has stopped receiving data packets from the PLC or controller for a time exceeding the timeout setting.

Causes

1. Disconnected Cable: The RS-485 + or - wires are broken or loose.
2. Interference: Electrical noise from power cables is corrupting the communication signal (EMI).
3. Master Stopped: The PLC or controller has stopped polling the drive.
4. Wrong Settings: Baud rate, parity, or station address mismatch.

Solution

Restore communications:
1. Check Wiring: Ensure daisy-chain wiring is secure. Use shielded twisted-pair cable for RS-485.
2. Termination Resistor: Ensure a 120-ohm resistor is installed at the end of the communication line.
3. Parameters: Verify Protocol (e.g., 9600, 8, N, 2) matches the PLC exactly.
4. Timeout Setting: Increase the "Transmission Fault Treatment" timeout parameter if the network is busy.
