What it means
N07332 appears while a flying restart is being carried out and reports that the maximum speed that can be reached is reduced. The drive raises it because at very high speeds problems associated with the flying restart can be encountered. It is therefore a hint about a limitation during the flying restart rather than a fault that stops the drive.
Why it appears
- The power ratio between the power unit and the motor is too high.
What to check
- No parameter changes are required — the manual gives this as the remedy, so leave the commissioning parameters as they are.
- Observe the manual's note:
A flying restart at speeds above 3000 rpm should be avoided.
If the application can reach such speeds, carry out the flying restart outside that speed range.
Acknowledging and restarting
Nothing has to be acknowledged or reset. The drive keeps running; the message simply points out the reduced maximum speed during the flying restart.
The same on every family
Every manual that describes N07332 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2794 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1543 |
The drives this code lives on

Questions technicians ask
What does N07332 mean on a SINAMICS drive?
The message appears during a flying restart and reports that the maximum speed that can be reached is reduced, because at very high speeds problems with the flying restart can occur.
How do I clear message N07332?
Nothing has to be acknowledged or reset. Parameter changes are not required — the manual states this explicitly as the remedy.
Why does N07332 appear?
The manual names a single cause: the power ratio between the power unit and the motor is too high.
May I perform a flying restart above 3000 rpm?
No. The manual notes that a flying restart at speeds above 3000 rpm should be avoided.
