What it means
F33895 means that a DRIVE-CLiQ communication error has occurred on the connection from the Sensor Module used as encoder 3 to the Control Unit. The error cause reported with the message is 11 (= 0B hex): a synchronization error during alternating cyclic data transfer. Depending on how the drive is configured, the same condition can also be signalled as an alarm or without any automatic reaction.
Why it appears
- The DRIVE-CLiQ link between the Sensor Module that supplies encoder 3 and the Control Unit has produced a communication error.
- The error cause encoded in the message, 11 (= 0B hex), is a synchronization error during alternating cyclic data transfer.
What to check
- Read the message value in r0949 (or in r2124 when the condition is signalled as an alarm) and decode it from the 0000yyxx hex pattern described below, so you know which component and which error cause were reported.
Carry out a POWER ON
— this is the remedy the manual gives for this fault.- The manual also cross-references p9915 (DRIVE-CLiQ data transfer error shutdown threshold master, DQ fault master) in connection with this fault.
Reading the message value
The message value consists of the component number (%1) and the fault cause (%2). The manual codes the individual information in the message value (r0949/r2124) as follows:
- 0000yyxx hex: yy = component number, xx = error cause
- Fault cause: 11 (= 0B hex): Synchronization error during alternating cyclic data transfer
Parameters the manual names
- r0949 (fault value): holds the message value of this fault, coded 0000yyxx hex, from which the component number and the error cause are read.
- r2124 (alarm value): holds the same coded information when the drive signals the condition as an alarm.
- p9915 (DRIVE-CLiQ data transfer error shutdown threshold master / DQ fault master): the parameter the manual cross-references under the remedy for this DRIVE-CLiQ data transfer error.
Acknowledging and restarting
The message must be acknowledged immediately. The only remedy the manual prescribes is to Carry out a POWER ON
, i.e. switch the drive off and back on again. When the same condition is only signalled as an alarm or without a reaction, the manual specifies neither an automatic reaction nor an acknowledgement; the coded information is then read from the alarm value r2124.
What differs between the drive families
Straight from the manuals' own fields — F33895 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 3 | SINAMICS G130, G150 List Manual · p. 1846 |
| 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 3 | SINAMICS S120, S150 List Manual · p. 3175 |

Questions technicians ask
What does fault F33895 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communication error on the connection from the Sensor Module of encoder 3 to the Control Unit. The reported fault cause 11 is a synchronization error during alternating cyclic data transfer.
How do I clear fault F33895?
Acknowledge the message immediately and carry out a POWER ON, which is the remedy the manual gives. If the condition is only signalled as an alarm or without reaction, no acknowledgement is specified.
What is stored in the message value of F33895?
The value in r0949 (or r2124 for an alarm) is coded 0000yyxx hex: yy is the component number and xx the error cause, which is 11 (= 0B hex) for this fault.
Which parameter is referenced for fault F33895?
The manual cross-references p9915, the DRIVE-CLiQ data transfer error shutdown threshold master (DQ fault master), under the remedy for this fault.
