What it means
F07334 'Function not possible' means the drive has selected a function that cannot be executed with the configuration currently active. Which function the drive rejected is shown by the fault value in r0949. Depending on the drive's configuration, the same condition can also be signalled only as an alarm (A) or with no reaction at all (N).
Why it appears
- The selected function is not possible for this configuration of the drive.
- Fault value 0: the function 'Travel to fixed end stop' (p1545) is selected although encoderless operation or U/f operation is active.
What to check
- Operate the closed-loop speed control with an encoder.
- If the fixed-stop function is not needed, deselect the function 'Travel to fixed stop' at p1545.
Reading the message value
- The drive writes the fault value into r0949 and the message value carries the same value; it is to be interpreted as a decimal number.
- 0 — the function 'Travel to fixed end stop' (p1545) was selected although encoderless operation or U/f operation is active.
Parameters the manual names
- r0949 — read the fault value here (interpret it as a decimal number) to see which function the drive could not execute for this code.
- p1545 — BI: Activates travel to a fixed stop (TfS activation); this is where the fixed-stop function is deselected if the drive runs encoderless or with U/f operation.
Acknowledging and restarting
When the message trips as a fault, the drive stops (OFF1) and the fault must be acknowledged immediately before the drive can be restarted. If the same condition is configured as an alarm (A) or with no reaction (N), the drive takes no action and no acknowledgement is required. Before restarting, remove the cause as described above so that the selected function can actually run.
The same on every family
Every manual that describes F07334 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Application/technological function faulted (17) | Motor | SINAMICS S120, S150 List Manual · p. 2794 |

Questions technicians ask
What does SINAMICS fault F07334 mean?
The drive reports that a function you have selected cannot be executed with the configuration that is currently active. Fault value 0 in r0949 means the function 'Travel to fixed end stop' (p1545) is selected although encoderless operation or U/f operation is active.
How do I clear fault F07334?
Either operate the closed-loop speed control with an encoder, or deselect the function 'Travel to fixed stop' at p1545 if it is not needed. Then acknowledge the fault immediately so the drive can be restarted.
Where do I read the fault value of F07334?
In r0949, and it is interpreted as a decimal number. A value of 0 identifies the fixed-end-stop function selected under encoderless or U/f operation.
Can F07334 appear as an alarm instead of a fault?
Yes. Depending on the configuration, the same condition can also be issued as an alarm (A) or with no reaction (N); in both cases the drive takes no action and no acknowledgement is required.
