SP1700
SAFETY PARAM ERROR
Fanuc · Alpha i Series Servo Amplifier
What does SP1700 mean?
The CNC CPU detected an error in the safety parameter check function. This indicates a potential issue with the integrity or validity of safety-related parameters within the CNC system, which could compromise overall machine safety.
Common Causes
- Safety parameter mismatch between CNC and servo drive.
- Corrupted safety parameter data stored in CNC memory.
- CNC CPU hardware issue affecting safety parameter storage or retrieval.
- Inconsistent safety configuration across different CNC axes or functions.
- Interruption during safety parameter initialization.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify safety parameters on CNC diagnostic screen against servo drive settings.
- 2
Reload safety parameters from a validated backup in the CNC.
- 3
Perform a CNC system reboot to clear temporary faults.
- 4
Check CNC parameters related to safety configuration (e.g., P1-11).
- 5
Ensure CNC battery backup is functional to maintain parameter integrity.
