This page covers FANUC CNC alarm codes 1001 and above for:
- FANUC Series 0i-Model D
- FANUC Series 0i Mate-Model D
These alarm references may appear as:
- PS alarms – Program-related alarms
- BG alarms – Background editing alarms
- SR alarms – Communication alarms
Important: PS, BG, and SR alarms use the same shared numeric alarm code system.
The alarm number alone does not identify the alarm type. The actual prefix is displayed only on the CNC system screen, such as PS1001, BG1095, or SR2032.
This page is useful for:
- CNC operators
- Maintenance engineers
- FANUC service technicians
- CNC programmers
- Buyers checking alarm meanings before repair or replacement
