What it means
F07332 appears when a flying restart is attempted and the maximum speed that can be reached is reduced. The reason the drive reports this: at very high speeds, problems associated with the flying restart can be encountered, so the reachable speed range is limited. The manuals name a single possible cause for the reduced range.
Why it appears
- The power ratio between power unit and motor is too high — the power unit is oversized relative to the motor it feeds.
What to check
- No parameter changes are required — the manual states this explicitly, so there is nothing to reparameterize for this message.
- Observe the speed limit the manual sets for the restart:
A flying restart at speeds above 3000 rpm should be avoided.
Acknowledging and restarting
The drive coasts down when this fault trips. The fault can be acknowledged immediately; since parameter changes are not required, the drive can be restarted as soon as it has been acknowledged, keeping the flying-restart speed within the range noted above.
What differs between the drive families
Straight from the manuals' own fields — F07332 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G120 | OFF2 (NONE, OFF1) | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 876 |
| G120XA | OFF2 (NONE, OFF1) | IMMEDIATELY | — | — | SINAMICS G120XA PN converter · p. 1126 |
The drives this code lives on
F07332 is described for G120, G120XA. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does F07332 mean on a SINAMICS G120 or G120XA?
It is raised during a flying restart when the maximum speed that can be reached is reduced, because at very high speeds problems associated with the flying restart can be encountered.
Why is the maximum speed reduced during a flying restart?
The manuals give one possible cause: the power ratio between power unit and motor is too high.
Do parameters need to be changed after fault F07332?
No. Parameter changes are not required — acknowledge the fault and avoid performing a flying restart at speeds above 3000 rpm.
