What it means
F30895 reports a DRIVE-CLiQ communication error that has occurred from the power unit (PU) to the Control Unit (CU) involved. The fault cause recorded with it is 11 (= 0B hex): a synchronization error during the alternating cyclic data transfer. The list-manual entries for these families describe this fault identically, so the meaning is the same on each of them.
Why it appears
- A DRIVE-CLiQ communication error has occurred from the power unit to the Control Unit involved.
- The reported fault cause is 11 (= 0B hex): a synchronization error occurred during the alternating cyclic data transfer.
What to check
- Read the message value: it is coded in r0949 (fault value) or r2124 (alarm value) and tells you the component number and the fault cause, i.e. which component reported the synchronization error.
- Carry out a POWER ON — switch the drive off and switch it on again. This is the remedy both entries give for this code.
- In the G130/G150 entry the remedy additionally refers to p9915 (DRIVE-CLiQ data transfer error shutdown threshold master).
Reading the message value
- The message value combines two items: the component number and the fault cause.
- The drive codes it in r0949 (fault value) / r2124 (alarm value) as 0000yyxx hex.
- yy = component number.
- xx = error cause; for this fault the error cause is 11 (= 0B hex), the synchronization error during the alternating cyclic data transfer.
Parameters the manual names
- r0949 (fault value): here you read the coded component number and fault cause of this fault.
- r2124 (alarm value): named by the manual alongside r0949 as the register in which the message value is coded.
- p9915 (DRIVE-CLiQ data transfer error shutdown threshold master): the G130/G150 remedy cross-refers to this parameter for this fault.
Acknowledging and restarting
The drive trips and the fault has to be acknowledged before it will start again. The only recovery the manuals describe for this code is to carry out a POWER ON — switching the power off and on again. No other reset procedure is given for F30895.
What differs between the drive families
Straight from the manuals' own fields — F30895 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: OFF2 (NONE, OFF1) Servo: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) Vector: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) Hla: OFF2 (NONE, OFF1, OFF3, STOP2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Power Module | SINAMICS S120, S150 List Manual · p. 3022 |
| G130, G150 | Vector: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) Infeed: OFF2 (NONE, OFF1) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Power Module | SINAMICS G130, G150 List Manual · p. 1713 |

Questions technicians ask
What does fault F30895 mean on a SINAMICS G130, G150, S120 or S150?
It reports a DRIVE-CLiQ communication error from the power unit to the Control Unit involved. The recorded fault cause is 11 (= 0B hex): a synchronization error during the alternating cyclic data transfer.
How do I clear F30895?
The manuals give one remedy: carry out a POWER ON, i.e. switch the drive off and switch it on again. The fault must then be acknowledged before the drive will restart.
How can I see which component reported F30895?
Read the message value in r0949 (or r2124). It is coded 0000yyxx hex, where yy is the component number and xx is the error cause — here 11 (= 0B hex).
What is parameter p9915 used for with F30895?
In the G130/G150 manual the remedy for this fault cross-refers to p9915, the DRIVE-CLiQ data transfer error shutdown threshold master. The entry gives no further instruction for this parameter on this fault.
