What it means
F34895 reports a DRIVE-CLiQ communications error between the Voltage Sensing Module (VSM) involved and the Control Unit. The fault cause recorded with the message is a synchronization error during alternating cyclic data transfer — fault cause 11 (= 0B hex). The manuals for G130, G150, S120 and S150 describe this fault identically, and in every entry the component named is the Voltage Sensing Module (VSM).
Why it appears
- The DRIVE-CLiQ connection from the Voltage Sensing Module (VSM) involved to the Control Unit has reported a communications error.
- The fault cause is 11 (= 0B hex): the synchronization of the alternating cyclic data transfer has failed.
What to check
- Read the message value in r0949 (fault value) or r2124 (alarm value): yy gives the number of the VSM involved, xx the error cause.
- Carry out the remedy the manuals give for this fault:
Carry out a POWER ON.
- The remedy entry for this fault also refers to p9915 (DRIVE-CLiQ data transfer error shutdown threshold master).
Reading the message value
- The message value consists of the component number (%1) and the fault cause (%2).
- The drive codes this information in the fault value r0949 / alarm value r2124 as 0000yyxx hex: yy = component number, xx = error cause.
- For this fault the error cause is 11 (= 0B hex), the synchronization error during alternating cyclic data transfer.
Parameters the manual names
- r0949 — fault value: here the drive stores this fault's coded message value; yy identifies the VSM involved, xx the fault cause.
- r2124 — alarm value: the counterpart in which the same coded information for this message is stored.
- p9915 — DRIVE-CLiQ data transfer error shutdown threshold master: the remedy for this fault cross-references this parameter.
Acknowledging and restarting
Acknowledge the fault immediately. The manuals give exactly one remedy for this fault: Carry out a POWER ON.
No further measures are described; the remedy entry additionally points to p9915 (DRIVE-CLiQ data transfer error shutdown threshold master).
What differs between the drive families
Straight from the manuals' own fields — F34895 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. 3193 |
| 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. 1863 |

Questions technicians ask
What does SINAMICS fault F34895 mean?
It reports a DRIVE-CLiQ communications error between the Voltage Sensing Module (VSM) and the Control Unit. The fault cause is 11 (= 0B hex): a synchronization error during alternating cyclic data transfer.
How do I clear fault F34895?
Acknowledge the fault immediately and carry out a POWER ON — this is the only remedy the manuals describe. The remedy entry additionally refers to p9915, the DRIVE-CLiQ data transfer error shutdown threshold master.
Which VSM reported fault F34895?
Read the coded message value in r0949 (fault value) or r2124 (alarm value): it is coded 0000yyxx hex, where yy is the component number of the VSM involved and xx the error cause.
What does p9915 have to do with F34895?
The manual's remedy for this fault cross-references p9915, the DRIVE-CLiQ data transfer error shutdown threshold master.
