What it means
A40101 announces that an alarm has occurred at the drive object connected at DRIVE-CLiQ socket X101. It points to another alarm rather than describing a fault of its own: the message value holds the alarm value from r2124, and that value is the first alarm that has occurred for this drive object. The G130, G150, S120 and S150 manuals describe the alarm identically, so the same steps apply everywhere.
Why it appears
- An alarm has occurred at the drive object at DRIVE-CLiQ socket X101.
- The alarm value in r2124 (interpret decimal) is the first alarm that has occurred for this drive object.
What to check
- Evaluate the alarm buffer of the drive object that the alarm specifies.
- Read the alarm value in r2124 and interpret it as decimal to identify the first alarm that has occurred for this drive object.
Reading the message value
- The message value %1 carries the alarm value. The manual decodes it as:
Alarm value (r2124, interpret decimal): First alarm that has occurred for this drive object.
- The value is a single decimal number, not a bit list.
Parameters the manual names
- r2124 — alarm value: read it and interpret the value as decimal; it holds the first alarm that has occurred for the drive object at DRIVE-CLiQ socket X101.
Acknowledging and restarting
No acknowledgement is required and the alarm does not stop the drive, so there is nothing to reset on the operator panel or in the commissioning tool. To deal with the condition, evaluate the alarm buffer of the specified drive object as described above and follow the alarm that r2124 identifies.
The same on every family
Every manual that describes A40101 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | General drive fault (19) | None | SINAMICS G130, G150 List Manual · p. 1923 |
| S120, S150 | NONE | NONE | General drive fault (19) | None | SINAMICS S120, S150 List Manual · p. 3280 |

Questions technicians ask
What does alarm A40101 mean in SINAMICS?
It reports that an alarm has occurred at the drive object at DRIVE-CLiQ socket X101. The alarm value in r2124, read as a decimal number, is the first alarm that has occurred for this drive object.
How do I fix alarm A40101?
Evaluate the alarm buffer of the drive object that the alarm specifies. The value in r2124 shows which alarm occurred first, so you can look that alarm up like any other code.
Does A40101 have to be acknowledged?
No. The alarm has no reaction and needs no acknowledgement, so there is nothing to reset at the operator panel.
Which parameter holds the alarm behind A40101?
r2124, the alarm value. Interpret the value as decimal — it gives the first alarm that has occurred for the drive object at socket X101.
