Safety parameterization changed, POWER ON required
Siemens · SINAMICS G120
What does F01693 mean?
Safety-related parameters have been modified, requiring a power cycle for the changes to take effect and be properly stored. Operating without a power cycle could result in an inconsistent or unapplied safety state, compromising machine safety.
Common Causes
- Modification of any safety-relevant parameter (e.g., p9500 (SLS enable), p9650 (STO timer)) without subsequent power cycling of the drive.
- A safety configuration upload or download operation was performed, but the system has not been rebooted to apply changes.
- Internal safety checksum mismatch detected after parameter changes, necessitating a full system re-initialization.
- Drive operating system requires a hardware reset to properly store and activate updated safety functionality.
Repair Steps & Checklist
Click steps to track your progress.
- 1
1. Power off the entire drive system (main supply, not just control power) and wait for the power module discharge LEDs to extinguish.
- 2
2. Power on the drive system to allow the new safety parameterization to take full effect and be stored in non-volatile memory.
- 3
3. After power cycling, verify the status of the modified safety parameters to confirm they are active and correctly stored.
- 4
4. If the fault persists, re-enter the safety-related parameter changes and ensure a complete power cycle follows.
- 5
5. Perform a safety signature comparison (e.g., r9750, r9751) to confirm consistency after power-up.
