MISSMATCH THE RESULTS OF SAFETY PARAMETER

Fanuc · Alpha i Series Servo Amplifier

Was bedeutet 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.

Häufige Ursachen

  • 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.
