What it means
The drive shows C30798 as SI Motion P2: Test stop for motion monitoring functions running
. The message is issued by the safety monitoring channel of the Safety Integrated (SI) motion monitoring while the forced checking procedure (test stop) for the safe motion monitoring functions is currently in progress. It reports a check that the drive is carrying out, not a condition the technician has to repair: the drive takes no automatic reaction, and the manuals give no remedy because none is necessary.
Why it appears
- The forced checking procedure (test stop) for the safe motion monitoring functions is currently in progress.
What to check
- No checks are necessary. The manuals state that the remedy is
Not necessary
— the message is automatically withdrawn when the test stop has been completed, so let the test stop finish and the message will disappear on its own.
Acknowledging and restarting
No acknowledgement is required in normal operation: the message is automatically withdrawn when the test stop has been completed
. If it should ever be necessary to remove the message before the test stop finishes, it belongs to the type that is cleared with a POWER ON — the drive's power supply has to be switched off and on again.
What differs between the drive families
Straight from the manuals' own fields — C30798 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 3013 |
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1704 |
| G120 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 930 |
The drives this code lives on

Questions technicians ask
What does C30798 mean on a SINAMICS drive?
It reports that the forced checking procedure (test stop) for the SI Motion P2 safe motion monitoring functions is currently in progress. The drive takes no automatic reaction, and no remedy is necessary.
How do I clear C30798?
Normally you do not have to clear it: the message is automatically withdrawn when the test stop has been completed. If it must be removed explicitly, it is cleared with a POWER ON, i.e. the drive's power supply is switched off and on again.
Why does my SINAMICS show C30798 when nothing is wrong?
The message comes from the safety monitoring channel while the test stop for the safe motion monitoring functions runs. It reflects the check currently in progress, which is why the manuals state that no remedy is necessary.
