Omron · NJ/NX-series Machine Automation Controller
The absolute encoder detected an error in its multi-rotation counting function. This is often caused by temporary issues like vibration, impact, condensation, or an internal encoder failure, leading to incorrect absolute position.
Click steps to track your progress.
Inspect the encoder for signs of physical impact, vibration, or moisture (condensation).
Ensure the encoder is securely mounted and isolated from excessive vibration.
Check environmental conditions (temperature, humidity) around the encoder.
