What it means
F35845 reports a DRIVE-CLiQ communication error between the Control Unit and the Terminal Module (TM) involved. The fault cause behind the message is a synchronization error during alternating cyclic data transfer, i.e. the cyclic exchange of data between the Control Unit and the Terminal Module has lost synchronization. The manuals give the same description for the G130, G150, S120 and S150, so the meaning and the handling are identical across these families.
Why it appears
- A DRIVE-CLiQ communication error has occurred between the Control Unit and the Terminal Module (TM) involved.
- The reported fault cause is 11 (= 0B hex): 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 of the Terminal Module involved, xx gives the fault cause.
- Carry out a POWER ON — this is the remedy the manual gives for this fault.
Reading the message value
- The drive codes the information in the message value (read in r0949 or r2124) as 0000yyxx hex: yy = component number, xx = error cause.
- For this fault the error cause is 11 (= 0B hex): synchronization error during alternating cyclic data transfer.
Parameters the manual names
- r0949 — fault value: holds the coded message value for this fault; decode it to identify the Terminal Module concerned and the fault cause.
- r2124 — alarm value: carries the same coded value (0000yyxx hex) alongside r0949.
- p9916 — DRIVE-CLiQ data transfer error shutdown threshold slave (DQ fault slave): the remedy for this fault refers to this parameter.
Acknowledging and restarting
The fault must be acknowledged immediately. The remedy consists of a single step: carry out a POWER ON. Once the drive has been powered up again and the fault has been acknowledged, it can be restarted.
The same on every family
Every manual that describes F35845 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (OFF2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3236 |
| G130, G150 | OFF1 (OFF2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1898 |

Questions technicians ask
What does fault F35845 in SINAMICS mean?
It reports a DRIVE-CLiQ communication error between the Control Unit and the Terminal Module (TM) involved — specifically a synchronization error during alternating cyclic data transfer.
How do I clear fault F35845?
Carry out a POWER ON, which is the only remedy the manual gives, and acknowledge the fault immediately. The drive can then be restarted.
How do I find out which Terminal Module triggered F35845?
Decode the message value in r0949 or r2124, which is coded 0000yyxx hex: yy is the component number of the Terminal Module and xx is the fault cause, here 11 (= 0B hex).
Which parameter does the manual refer to for F35845?
p9916, the DRIVE-CLiQ data transfer error shutdown threshold slave, which the manual lists under this fault's remedy.
