What it means
F30845 is raised on the power unit when the cyclic data transfer over DRIVE-CLiQ from the Control Unit to the power unit concerned has failed. The manuals name one fault cause for this code: 11, a synchronization error during alternating cyclic data transfer.
Why it appears
- A DRIVE-CLiQ communication error has occurred on the link from the Control Unit to the power unit concerned.
- The fault cause reported by the power unit is 11: a synchronization error during alternating cyclic data transfer.
What to check
- Carry out a POWER ON: switch the drive off and then on again.
- Go to p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave), to which the remedy cross-refers.
Reading the message value
- The message value carries two items: the component number (%1) and the fault cause (%2).
- The manual codes both items in the message value, read in r0949 or r2124, as 0000yyxx hex: yy = component number, xx = error cause.
- The only fault cause the manuals print for this code is 11, the synchronization error during alternating cyclic data transfer.
Parameters the manual names
- r0949 (fault value): read the coded message value of F30845 here — the component number and the fault cause.
- r2124 (alarm value): named by the manual alongside r0949 as the place holding the same coded value.
- p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave): the remedy for this fault cross-refers to this parameter.
Acknowledging and restarting
The fault must be acknowledged immediately. The remedy the manuals give is to Carry out a POWER ON (switch-off/switch-on)
— switch the drive off and back on again. The drive is restarted once the fault has been acknowledged and the POWER ON has been carried out.
What differs between the drive families
Straight from the manuals' own fields — F30845 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | — | — | Internal (DRIVE-CLiQ) communication error (12) | Power Module | SINAMICS S120, S150 List Manual · p. 3017 |
| G130, G150 | OFF2 | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Power Module | SINAMICS G130, G150 List Manual · p. 1709 |

Questions technicians ask
What does fault F30845 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communication error in the cyclic data transfer from the Control Unit to the power unit concerned. The fault cause is 11: a synchronization error during alternating cyclic data transfer.
How do I clear fault F30845?
Carry out a POWER ON (switch the drive off and on again) and acknowledge the fault immediately. The remedy also cross-refers to p9916, the DRIVE-CLiQ data transfer error shutdown threshold slave.
Where can I read the component number and fault cause for F30845?
In the message value in r0949 or r2124, coded 0000yyxx hex, where yy is the component number and xx the error cause. For this fault the printed fault cause is 11.
