  • There is excessive noise

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify the status of the encoder's multi-turn backup battery or internal power storage, and replace if indicated.

  2. 2

    Inspect the encoder feedback cable for physical damage, proper shielding, and secure connections at both the encoder/motor and the servo drive/controller.

  3. 3

    Check the encoder configuration parameters in the Omron NJ/NX controller and the connected servo drive (if applicable) for correct encoder type, resolution, and multi-turn settings.

  4. 4

    Execute the absolute position re-initialization or data clear procedure for the affected axis as described in the Omron servo drive and NJ/NX documentation.
