What it means
F37313 is raised when the HF Choke Module — the reactor module of the drive line-up — has signaled overtemperature or a fan failure (alarm A37312) continuously for longer than 30 s. The drive then trips and stays switched off until the fault has been acknowledged.
Why it appears
- Alarm A37312, which displays overtemperature or fan failure in the HF Choke Module, has been signaled for longer than 30 s.
What to check
- Check the cable between the HF Choke Module and the HF Damping Module at connector X21; it may have been withdrawn or be defective.
- Check the fan of the HF Choke Module and replace it if necessary.
- Check whether the ambient temperature is in the permissible range.
Acknowledging and restarting
Remove the cause first. The fault is cleared by switching the drive power supply off and on again; the drive only restarts once the fault has been acknowledged this way.
The same on every family
Every manual that describes F37313 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY (POWER ON) | Power electronics faulted (5) | None | SINAMICS S120, S150 List Manual · p. 3268 |

Questions technicians ask
What does fault F37313 mean on a SINAMICS drive?
It means the HF Choke Module has reported overtemperature or fan failure (alarm A37312) for longer than 30 s, so the drive has tripped.
How is fault F37313 reset?
Eliminate the cause first, then switch the drive power supply off and on again — the fault is acknowledged with this POWER ON and the drive can then restart.
What should I check when F37313 appears?
Check the X21 cable between the HF Choke Module and the HF Damping Module, check the fan of the HF Choke Module and replace it if necessary, and confirm that the ambient temperature is in the permissible range.
