What it means
F34886 reports a DRIVE-CLiQ (CU) send error: a DRIVE-CLiQ communications error has occurred between the Voltage Sensing Module (VSM) involved and the Control Unit, so the VSM's data could not be sent. The manuals describe this fault for the G130, G150, S120 and S150 in the same words. The drive records in the message value which component reported the fault and why; here the cause is a telegram type that does not match the send list.
Why it appears
- A DRIVE-CLiQ communications error occurred on the path from the Voltage Sensing Module (VSM) involved to the Control Unit — the data were not able to be sent.
- The fault cause reported by the component is 65 (= 41 hex): the telegram type does not match the send list.
What to check
Carry out a POWER ON.
Switch the drive's power supply off and back on again — the manual lists no other remedial step for this fault.
Reading the message value
- The message value carries the component number (%1) and the fault cause (%2).
- The information is coded in r0949/r2124 as 0000yyxx hex: yy = component number, xx = error cause.
- For this fault the error cause (xx) is 65 (= 41 hex), the telegram-type mismatch; the component number (yy) identifies the Voltage Sensing Module involved.
Parameters the manual names
- r0949 (fault value) — read the coded message value 0000yyxx hex here to see which component reported F34886 and with which fault cause.
- r2124 (alarm value) — the storage named alongside r0949 holding the same coded component number and error cause for this code.
Acknowledging and restarting
The fault can be acknowledged immediately. The only remedy the manual gives is a POWER ON: switch the drive's power supply off and back on again, then restart the drive.
What differs between the drive families
Straight from the manuals' own fields — F34886 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: OFF2 (NONE, OFF1) Servo: NONE (OFF1, OFF2) Vector: NONE (OFF1, OFF2) Hla: NONE (OFF1, OFF2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Voltage Sensing Module (VSM) | SINAMICS S120, S150 List Manual · p. 3192 |
| G130, G150 | Vector: NONE (OFF1, OFF2) Infeed: OFF2 (NONE, OFF1) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Voltage Sensing Module (VSM) | SINAMICS G130, G150 List Manual · p. 1862 |

Questions technicians ask
What does fault F34886 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communication error between the Voltage Sensing Module (VSM) and the Control Unit: the VSM's data could not be sent. The fault cause is 65 (= 41 hex) — the telegram type does not match the send list.
How do I clear fault F34886?
The manual gives exactly one remedy: carry out a POWER ON, i.e. switch the drive's power supply off and back on again. The fault can then be acknowledged immediately.
Where can I read which component caused F34886?
In the fault value r0949 (or alarm value r2124). The value is coded 0000yyxx hex: yy is the component number, xx the error cause.
Which drives know fault F34886?
The manuals describe it for G130, G150, S120 and S150, with the same meaning on each.
