SP9078
MISSMATCH THE RESULTS OF SAFETY PARAMETER
Fanuc · Alpha i Series Servo Amplifier
¿Qué significa SP9078 ?
The spindle CPU detected a mismatch between the CNC result of the safety parameters check and the spindle's own result. This indicates an inconsistency in safety parameter values (No.4372/No.4438/No.4440/No.4442/No.4448) between the CNC and spindle, potentially affecting safety operations.
Causas comunes
- Safety parameters stored in different locations do not match.
- Data inconsistency in safety configuration stored across multiple memory units.
- Checksum error on safety parameter blocks.
- Failed write operation to non-volatile safety parameter memory.
