Causes and Fixes

1
Review the NC program block that triggered the alarm and verify the search syntax (G75 or similar) includes correct axis designation and search direction.
2
Check machine data MD34200 $MA_ENC_REFP_MODE for the affected axis to ensure reference point mode is correctly configured for the encoder type installed.
3
Verify machine data MD34210 $MA_ENC_REFP_CAM_DIR_IS_MINUS for correct reference cam direction setting matching your machine's physical configuration.
4
Inspect MD34100 $MA_REFP_CAM_DIR_IS_MINUS to ensure the reference cam direction for the axis matches the actual hardware setup and search direction in the program.
