F46 (MMX/MMV): No movement
Code Meaning: The encoder is not moving.
Further Information/Troubleshooting Tips:
- Check to see if the encoder coupling has come loose. Tighten or fix as necessary.
- Check that your encoder is properly grounded. Consult the documentation or manual for your encoder as necessary.
- Run the drive in test mode (U49) with U48 set to 17 to detect noise levels, and to see if there are specific times when the noise is occurring. If the noise appears when the brake is setting/releasing, your brake contactors may be causing interference with the encoder. Isolate and shield encoder wiring if possible to reduce sources of EMF noise.
