Encoder Data Restoration Error

What does 08170000 hex mean?

Initialization of internal position data was not processed correctly in Semi-closed Control Mode and Absolute Value Mode. This implies a failure to correctly establish the encoder's initial position, affecting control accuracy.

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

Click steps to track your progress.

1. 1

   Inspect all encoder cable connections at both the absolute encoder and the Omron NJ/NX controller for looseness, damage, or incorrect pinout.

2. 2

   Measure the supply voltage at the absolute encoder input terminals to confirm it meets the encoder manufacturer's specifications.

3. 3

   Verify the absolute encoder parameters and settings within the Omron NJ/NX controller, including encoder type, resolution, and absolute position initialization method, against the machine's configuration documentation.

4. 4

   Check for any signs of electrical noise or interference affecting the encoder signal cable, especially in proximity to power cables or inductive loads.
