What it means
A30772 is the SI Motion P2 alarm that reports the test stop for the fail-safe digital outputs — the manual's note abbreviates them as F-DO (Failsafe Digital Output) — is currently running: the drive is in the middle of its forced checking procedure. The S120/S150 and G130/G150 manuals describe this code with the same cause and the same automatic withdrawal, so the alarm behaves identically on all of these converters.
Why it appears
- The forced checking procedure (test stop) for the fail-safe digital inputs is currently in progress; the drive raises the alarm for as long as this procedure runs. The alarm title and the manual's note (F-DO — Failsafe Digital Output) speak of the fail-safe digital outputs, and the S120/S150 and G130/G150 entries print this identical cause.
What to check
- Let the running test stop finish — the alarm only accompanies this procedure, and the remedy prescribes no intervention of your own.
- Expect the alarm to withdraw itself once the test stop has ended successfully or has been canceled; the manual notes that the canceling case occurs when a fault condition occurs.
Acknowledging and restarting
No acknowledgment is needed. The alarm withdraws automatically after the test stop has ended successfully or has been canceled (when a fault condition occurs), the drive takes no reaction while A30772 is present, and you do not have to clear it on the operator panel or in the commissioning tool.
What differs between the drive families
Straight from the manuals' own fields — A30772 is not described identically everywhere.

| G130, G150 | NONE | NONE | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1702 |

Questions technicians ask
What does SINAMICS alarm A30772 mean?
The SI Motion P2 test stop for the fail-safe digital outputs (F-DO) is currently running — the drive is executing its forced checking procedure. The code means the same on the G130, G150, S120 and S150.
How do I clear or acknowledge A30772?
You do not acknowledge it. The alarm withdraws automatically after the test stop has ended successfully or has been canceled (when a fault condition occurs).
Why does A30772 appear on my drive?
The only cause the manuals print is that the forced checking procedure (test stop) is currently in progress; the alarm disappears again when that procedure ends or is canceled.
Does alarm A30772 stop the SINAMICS drive?
No. The drive takes no reaction to this alarm; it only reports the running test stop and clears itself afterwards.
