ILLEGAL REFERENCE AREA

What does DS0012 mean?

This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected an invalid reference area. This typically points to issues with the machine's established home position or coordinate offsets.

• Incorrectly established reference position (zero return) for an axis.
• Corrupted or invalid offset data (e.g., work offsets, tool offsets).
• Physical obstruction or interference near the reference point preventing proper homing.
• Parameter error related to defining the reference area or limits.

Click steps to track your progress.

1. 1

   Re-establish the machine's reference position (zero return) for the affected axis or axes.

2. 2

   Verify all offset values (tool offsets, work offsets, G50/G92) to ensure they are correctly set and not conflicting.

3. 3

   Check the machine's limit switch and reference switch functionality for proper operation and physical integrity.

4. 4

   Inspect the physical area around the reference point for any obstructions or debris.

5. 5

   Review relevant parameters that define the reference area or reference position settings for correctness.
