A communication error has occurred on the automation interface (AIF). This indicates a problem with the physical communication link, its configuration, or the communication master. This error is managed by parameter C0126.
Click steps to track your progress.
1. Visually inspect the communication cable connected to the drive's AIF port (e.g., X10) for damage; replace if frayed or broken.
2. Verify communication parameters (e.g., baud rate P5-01, address P5-02, parity P5-03) in the drive and compare with the master's settings.
3. Check for proper shielding continuity of the communication cable by measuring resistance between the shield and ground at both ends.
4. Temporarily disconnect other devices from the communication bus and test communication with only the drive and master to isolate interference.
5. Monitor the communication status indicator LEDs on the AIF module for activity and error signals.
