What it means
F36845 is raised when a DRIVE-CLiQ communications error occurs from the Control Unit to the DRIVE-CLiQ Hub Module involved. The recorded fault cause is 11: a synchronization error during alternating cyclic data transfer. The G130/G150 and the S120/S150 manuals describe this same condition, so the explanation below applies on all four families. The drive takes no automatic reaction of its own to this fault, but the fault must be acknowledged immediately.
Why it appears
- A DRIVE-CLiQ communication error occurred between the Control Unit and the DRIVE-CLiQ Hub Module involved.
- The fault cause recorded for this message is 11 — a synchronization error during alternating cyclic data transfer.
What to check
- Carry out a POWER ON: switch the drive's power supply off and back on again. Both manuals give this as the remedy for the fault.
- The G130/G150 description additionally cross-references p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave) for this message.
Reading the message value
- The message value carries two items: the component number (%1) and the fault cause (%2).
- The information is coded in r0949 or r2124 as 0000yyxx hex: yy = component number, xx = error cause.
- For this fault the error cause is 11, the synchronization error during alternating cyclic data transfer.
Parameters the manual names
- r0949 (fault value): holds the coded message value of this fault — component number and fault cause in the 0000yyxx hex pattern described above.
- r2124 (alarm value): the register the manual names alongside r0949 for the coded value of this message.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave): the parameter the G130/G150 entry points to for this fault.
Acknowledging and restarting
Acknowledge the fault immediately. The remedy the manuals give is to carry out a POWER ON — switch the drive's power supply off and back on again.
What differs between the drive families
Straight from the manuals' own fields — F36845 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Board (TB) | SINAMICS G130, G150 List Manual · p. 1916 |
| S120, S150 | — | — | Internal (DRIVE-CLiQ) communication error (12) | Terminal Board (TB) | SINAMICS S120, S150 List Manual · p. 3254 |

Questions technicians ask
What does fault F36845 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communications error from the Control Unit to the DRIVE-CLiQ Hub Module involved. The recorded cause is fault cause 11, a synchronization error during alternating cyclic data transfer.
How do I clear fault F36845?
Acknowledge it immediately and carry out a POWER ON — switch the drive's power supply off and back on again, which both manuals give as the remedy.
How is the message value of F36845 decoded?
The value in r0949 or r2124 is coded 0000yyxx hex: yy is the component number and xx is the error cause, which is 11 for this fault.
Which parameter is linked to F36845?
p9916, the DRIVE-CLiQ data transfer error shutdown threshold slave, is cross-referenced in the G130/G150 description of this fault.
