External Encoder Data Restoration Error

What does 08180000 hex mean?

Initialization of internal position data was not processed correctly in Fully-closed Control Mode and Absolute Value Mode. This is similar to the internal encoder error but specific to external encoders used in fully-closed loop systems.

• There is insufficient power supply voltage for the external encoder.
• Noise is entering on the external encoder line.

Click steps to track your progress.

1. 1

   Verify the external encoder's power supply voltage at the encoder terminals and controller input against manufacturer specifications.

2. 2

   Inspect all external encoder cabling for physical damage, proper routing, secure connections, and correct shielding termination at both the encoder and controller ends.

3. 3

   Check Omron Sysmac Studio for correct external encoder module configuration, associated axis parameters (e.g., resolution, scaling, data format), and fully-closed loop settings.

4. 4

   Perform a controlled power cycle of the Omron NJ/NX controller and associated servo system to force a fresh re-initialization of all connected devices.
