ILLEGAL MCN COODINATE

What does IE0009 mean?

This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected a displacement of a machine coordinate at a check point. This implies an inconsistency in the machine's internal position tracking.

• Loss of the machine's reference position (home position) due to power loss or encoder issue.
• Incorrect machine coordinate offset or work offset applied.
• Faulty position feedback device (encoder/scale) or its connection.
• Unexpected mechanical shift or slippage in the axis drive system.

Click steps to track your progress.

1. 1

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

2. 2

   Verify that no unexpected shifts or offsets have been applied to the machine coordinate system (e.g., G50/G92 offsets).

3. 3

   Check the integrity and mounting of the position feedback device (encoder/scale) for the affected axis.

4. 4

   Review diagnostic screens for any discrepancies between the commanded position and actual machine position.

5. 5

   Inspect mechanical components for signs of slippage or excessive backlash that could affect coordinate accuracy.
