What it means
F40001 is raised when a fault has occurred at the drive object connected at DRIVE-CLiQ socket X101. The code does not describe the underlying problem itself — it marks where the first fault occurred, and the drive stores the corresponding fault value in r0949, which must be interpreted as a decimal number. The manuals for G130, G150, S120 and S150 describe this fault identically, and the drive initiates no reaction of its own for this code.
Why it appears
- A fault has occurred at the drive object at DRIVE-CLiQ socket X101.
- F40001 refers to the first fault that has occurred for this drive object; which fault that actually is can only be seen from the fault value in r0949 (interpret decimal).
What to check
- Read the fault value of F40001 in r0949 and interpret it as a decimal number.
- Evaluate the fault buffer of the specified object — the drive object connected at DRIVE-CLiQ socket X101.
- Identify the fault shown in that buffer, remedy it according to its own entry, and then acknowledge F40001.
Reading the message value
- The drive writes the fault value of F40001 into r0949; interpret the value as a decimal number.
- Meaning of the value:
First fault that has occurred for this drive object.
Parameters the manual names
- r0949 — holds the fault value of this fault; read it as a decimal number to identify the first fault that occurred for the drive object at socket X101.
Acknowledging and restarting
F40001 must be acknowledged immediately. First evaluate the fault buffer of the drive object at socket X101 to establish which fault is actually present; once that fault has been remedied, acknowledge F40001.
The same on every family
Every manual that describes F40001 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY | General drive fault (19) | None | SINAMICS G130, G150 List Manual · p. 1922 |
| S120, S150 | NONE | IMMEDIATELY | General drive fault (19) | None | SINAMICS S120, S150 List Manual · p. 3279 |

Questions technicians ask
What does fault F40001 mean on a SINAMICS drive?
It reports that a fault has occurred at the drive object connected at DRIVE-CLiQ socket X101. The code marks the first fault for that object; the fault value in r0949 identifies which fault it is.
How do I clear F40001?
Evaluate the fault buffer of the drive object at socket X101 — it shows the fault that actually occurred. Remedy that fault according to its own entry and then acknowledge F40001 immediately.
Which parameter holds the fault value of F40001?
r0949. Read the value stored there as a decimal number; it is the first fault that occurred for the drive object behind socket X101.
Does F40001 behave the same on G130, G150, S120 and S150?
Yes — the manuals for these families describe the fault with the same cause, fault value and remedy.
