Fanuc alarm SP9076: SAFETY FUNCTION NOT EXECUTED
spindle alarm (serial spindle, alpha i) · Fanuc 0i-D
What it means
The safety-related processing that must run periodically in the spindle monitoring chain was not executed within its required interval. Dual Check Safety watchdogs expect deterministic cyclic execution; a missed cycle indicates the safety software or its supporting hardware stalled.
Likely causes
- CPU overload or stall preventing cyclic safety processing
- Defective option/board hardware supporting the safety function
- Configuration error after a safety-system modification
Triage note: Requires Fanuc-qualified revalidation before return to service.
