What it means
F40005 reports that a fault has occurred at the drive object connected at the DRIVE-CLiQ socket X105. The code itself does not name the underlying cause — it points to the object behind socket X105. The fault value stored in r0949 (interpret decimal) identifies the first fault that has occurred for this drive object, and the list manuals for G130/G150 and S120/S150 describe the code identically for all drive objects. The drive triggers no automatic response to this fault, but it must be acknowledged immediately.
Why it appears
- A fault has occurred at the drive object connected at the DRIVE-CLiQ socket X105.
- This code is raised for the first fault that has occurred for that drive object; the actual fault cause lies with the object itself, not with this code.
What to check
- Read the fault value in r0949 and interpret it as a decimal number — it names the first fault that has occurred for the drive object at socket X105.
Evaluate the fault buffer of the specified object.
The object meant is the one connected at DRIVE-CLiQ socket X105; the fault listed there carries its own cause and remedy.
Reading the message value
- The drive writes the fault value into r0949; interpret it as a decimal number.
- The value identifies the first fault that has occurred for the drive object at socket X105. The manual prints no bit decoding for this code.
- The manual also prints the message value as the placeholder %1, which carries this same information — the first fault that has occurred for this drive object.
Parameters the manual names
- r0949 — fault value: for this code, read it as a decimal number to obtain the first fault that has occurred for the drive object at socket X105; that is the entry to evaluate in the object's fault buffer.
Acknowledging and restarting
The drive takes no automatic reaction to this code, so nothing trips or coasts down by itself. Once the fault found in the specified object's fault buffer has been remedied, acknowledge F40005 immediately.
What differs between the drive families
Straight from the manuals' own fields — F40005 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY | General drive fault (19) | None | SINAMICS G130, G150 List Manual · p. 1923 |
| S120, S150 | — | — | General drive fault (19) | None | SINAMICS S120, S150 List Manual · p. 3279 |

Questions technicians ask
What does SINAMICS fault F40005 mean?
It reports that a fault has occurred at the drive object connected at DRIVE-CLiQ socket X105. The value in r0949 names the first fault that has occurred for that object.
How do I clear fault F40005?
Evaluate the fault buffer of the drive object at socket X105 and remedy the fault listed there. Then acknowledge F40005 immediately.
Where is the actual cause of F40005 stored?
In r0949, interpreted as a decimal number, and in the fault buffer of the specified drive object. The code itself names no cause of its own.
Does F40005 stop the drive?
No automatic reaction is triggered for this fault. The code only points to the fault at the object behind socket X105 and must be acknowledged immediately.
