1. 1

   Inspect the entire cable run between the external encoder and the Omron NJ/NX controller for physical damage, wear, and proper termination at both ends.

2. 2

   Verify the continuity of the Z-phase signal wire, its return path, and shield (if applicable) using a multimeter between the encoder connector and the Omron NJ/NX controller's input terminals.

3. 3

   Measure the supply voltage at the external encoder's power input terminals to confirm it meets the manufacturer's specified voltage range.

4. 4

   Check the encoder input parameters within the Omron NJ/NX controller's Sysmac Studio software, ensuring correct Z-phase input settings and encoder type configuration.

5. 5

   Monitor the Z-phase input status in the Omron NJ/NX controller's diagnostic tools (e.g., I/O monitor) while slowly rotating the encoder to confirm signal detection.
