What it means
F37845 is the fault HF Damping Module: Cyclic data transmission error
on the S120 and S150. The drive raises it when there is a DRIVE-CLiQ communication error between the Control Unit and the HF Damping Module; the fault cause recorded with this message is 11, a synchronization error during alternating cyclic data transfer. The fault does not trip the drive, but it must be acknowledged immediately.
Why it appears
- A DRIVE-CLiQ communication error has occurred between the Control Unit and the HF Damping Module.
- The fault cause entered in the message value is 11: a synchronization error during alternating cyclic data transfer.
What to check
- Read the message value in r0949 (or r2124) and decode it as 0000yyxx hex: yy gives the component number and xx the error cause, so you can see which component reported the synchronization error.
- Carry out a POWER ON — this is the remedy the manual gives for this fault.
Reading the message value
- The message value carries two items: the component number (%1) and the fault cause (%2).
- The manual codes the information in the message value (r0949/r2124) as 0000yyxx hex: yy = component number, xx = error cause.
Parameters the manual names
- r0949 — fault value: shows the message value of F37845, from which you read the component number and the fault cause reported for the HF Damping Module.
- r2124 — alarm value: named by the manual next to r0949 as the register in which the coded information of this message can be read.
Acknowledging and restarting
Acknowledge the fault immediately. The remedy the manual gives is to carry out a POWER ON. Because the fault triggers no stop reaction, the drive keeps running; once the fault has been acknowledged and the POWER ON carried out, the message is cleared. If F37845 returns, the component number in r0949 shows which component is reporting the DRIVE-CLiQ error.
The same on every family
Every manual that describes F37845 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | None | SINAMICS S120, S150 List Manual · p. 3272 |

Questions technicians ask
What does fault F37845 mean on a SINAMICS S120 or S150?
It reports a DRIVE-CLiQ communication error between the Control Unit and the HF Damping Module. The specific fault cause is 11, a synchronization error during alternating cyclic data transfer.
How do I clear fault F37845?
Carry out a POWER ON — that is the remedy the manual gives. The fault must also be acknowledged immediately.
Where do I find the component number and fault cause of F37845?
In the message value, which you can read in r0949 (fault value) or r2124 (alarm value). It is coded 0000yyxx hex: yy is the component number and xx the error cause.
Does F37845 stop the drive?
No stop reaction is triggered, so the drive keeps running. The fault still has to be acknowledged immediately.
