Absolute Position Detection Error
Omron · NJ/NX-series Machine Automation Controller
What does 08460000 hex mean?
The encoder detected a multi-rotation counter error. This fault points to an issue with the encoder's multi-rotation detection section, affecting the absolute positioning capability.
Common Causes
- A detection error was detected in the multi-rotation detection section of the encoder
- There is excessive noise
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the status of the encoder's multi-turn backup battery or internal power storage, and replace if indicated.
- 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
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
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.
