Omron · NJ/NX-series Machine Automation Controller
The encoder detected a one-rotation counter error. This implies an issue with the encoder's ability to accurately count single rotations, affecting position feedback.
Click steps to track your progress.
Measure the supply voltage at the encoder input terminals to verify it is within the specified nominal range.
Inspect the entire encoder cable for physical damage, proper shielding, and ensure all connections at the encoder and the Omron NJ/NX controller are secure and correctly terminated.
Check the mechanical mounting of the encoder to the rotating shaft for any looseness, slippage, or excessive vibration that could affect rotational accuracy.
Verify the encoder's configuration parameters (e.g., resolution, counting mode, signal type) within the Omron NJ/NX Controller match the specifications of the installed encoder.
