What it means
F32845 is raised when the drive detects a DRIVE-CLiQ communication error on the path from the Control Unit to the encoder connected as Encoder 2 (Sensor Module Encoder 2). The cause stored with the fault is number 11: a synchronization error during the alternating cyclic data transfer. Depending on the drive configuration, the same condition can also be output as an alarm (A) or without any reaction (N). When it trips as a fault, the drive is stopped with the OFF1 response (IASC/DCBRK) and the fault must be acknowledged before the drive can run again.
Why it appears
- A DRIVE-CLiQ communication error has occurred from the Control Unit to the encoder involved.
- The fault cause recorded is 11: a synchronization error during the alternating cyclic data transfer between the Control Unit and the encoder.
What to check
- Carry out a POWER ON (switch-off/switch-on) — this is the remedy the manual prescribes for this fault.
- The remedy also points to p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave): check this parameter as part of clearing the fault.
Reading the message value
- The drive enters two pieces of information into the message value: the component number (%1) and the fault cause (%2).
- The message value is coded in r0949 (fault value) / r2124 (alarm value) as 0000yyxx hex, where yy is the component number and xx is the error cause.
- Fault cause 11: synchronization error during alternating cyclic data transfer.
Parameters the manual names
- r0949 (Fault value): read the coded message value here to determine the component number and the fault cause behind F32845.
- r2124 (Alarm value): carries the same coded value when the condition is output as an alarm.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave, DQ fault slave): the remedy for this fault points to this parameter — check its setting when the fault occurs.
Acknowledging and restarting
Acknowledge F32845 immediately and carry out a POWER ON: switch the drive off and then switch it on again. Once the fault has been acknowledged and the POWER ON has been performed, the drive can be restarted.
What differs between the drive families
Straight from the manuals' own fields — F32845 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1797 |
| S120, S150 | Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Hla: OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3120 |

Questions technicians ask
What does fault F32845 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communication error from the Control Unit to the encoder on Encoder 2; the stored fault cause is 11, a synchronization error during alternating cyclic data transfer.
How do I fix F32845?
Acknowledge the fault immediately and carry out a POWER ON (switch the drive off and on again). The manual's remedy also points to p9916, the DRIVE-CLiQ data transfer error shutdown threshold slave.
Where can I read the fault cause of F32845?
In the message value r0949 (fault value) or r2124 (alarm value), coded as 0000yyxx hex: yy is the component number and xx is the error cause; a value of 11 means the synchronization error during alternating cyclic data transfer.
Can F32845 also appear as an alarm?
Yes. Depending on the drive configuration, the same condition can be output as an alarm or without any reaction instead of a fault.
