What it means
The manuals describe this fault as SI CU: Safety parameter settings and topology changed, warm restart/POWER ON
. It is raised in two steps: safety parameters have been changed, and such changes only take effect after a warm restart or a POWER ON — the cause text refers to alarm A01693 in this context. Despite that, a partial power up (boot) was then performed with the modified configuration. While the fault is active the drive coasts down and only starts again once the changed settings have been activated by the required restart.
Why it appears
- Safety parameters have been changed; these changes only take effect after a warm restart or a POWER ON. The drive's cause text refers here to alarm A01693.
- A partial power up (boot) was then performed with the modified configuration, i.e. before the required warm restart or POWER ON had been carried out.
What to check
- Carry out a warm restart: set p0009 = 30 and run the reset via p0976 with the value 2 or 3.
- Alternatively, carry out a POWER ON: switch the power supply off and on again for all components.
Parameters the manual names
- p0009 — device commissioning parameter filter (Dev com par_filt): set to 30 for the warm restart that activates the changed safety parameters.
- p0976 — reset and load all parameters (Reset load all par): run with the value 2 or 3 to carry out the warm restart named in the remedy.
Acknowledging and restarting
Both remedies activate the changed safety parameters and clear the fault: the warm restart with p0009 = 30 and p0976 = 2 or 3, or a POWER ON (switch-off/switch-on) for all components. The drive accepts a new start command only after this acknowledgement, so the restart must actually be performed before the drive can run again.
The same on every family
Every manual that describes F01679 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 (OFF1, OFF3) | POWER ON | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2652 |
| G130, G150 | OFF2 (OFF1, OFF3) | POWER ON | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1450 |

Questions technicians ask
What does fault F01679 mean in SINAMICS?
Safety parameters were changed, and although they only take effect after a warm restart or POWER ON, a partial power up (boot) was then performed with the modified configuration. The drive coasts down until the required restart is done.
How do I clear fault F01679?
Carry out a warm restart with p0009 = 30 and p0976 = 2 or 3, or switch the power supply off and on again for all components. The changed safety parameters then take effect and the fault can be cleared.
Can I acknowledge F01679 without a POWER ON?
The manual lists exactly two ways: the warm restart with p0009 = 30 and p0976 = 2 or 3, and the POWER ON (switch-off/switch-on) for all components. No panel reset is named for this fault.
What is the difference between A01693 and F01679?
The cause text of F01679 refers to alarm A01693, which accompanies changed safety parameters that still need a warm restart or POWER ON to take effect. F01679 follows when a partial boot was then carried out with the modified configuration.
