F0228 fault in WEG CFW500 Drive indicates a Telegram Reception Timeout. This means the serial network link dropped out completely before new control data was received from the master.
Cause:
- Pulse feedback input circuit fault.
- Broken cable, general installation grounding faults, or loose terminal contacts.
- The master controller is not sending telegrams within the time window set in parameter P0314.
Remedy:
Check serial communication cables, connectors, and shield grounding lines. Ensure the master’s polling interval is shorter than parameter P0314, or disable this timeout check in parameter P0314. Inspect the pulse feedback loop cabling.
