What it means
A40103 is raised when an alarm has occurred at the drive object at DRIVE-CLiQ socket X103. The alarm names no fault cause of its own: its value identifies the first alarm that has occurred for this drive object, so the actual message behind it must be read from that value. The other DRIVE-CLiQ sockets X100, X101, X102, X104 and X105 have their own alarms under the codes A40100, A40101, A40102, A40104 and A40105.
Why it appears
- An alarm has occurred at the drive object at DRIVE-CLiQ socket X103.
- No cause beyond that is given: the alarm only reports that another alarm has been raised, and the alarm value states which one it is.
What to check
- Take the alarm value from r2124 and interpret it as a decimal number — it is the first alarm that has occurred for this drive object.
- Evaluate the alarm buffer of the affected drive object to find the alarm behind this message; that alarm, not A40103 itself, is what has to be dealt with.
Reading the message value
- The drive enters the alarm value of the affected drive object as the message value.
- It is read from r2124 and interpreted as a decimal number: the value is the first alarm that has occurred for this drive object.
- No bit-by-bit decoding is printed for this value.
Parameters the manual names
- r2124 (alarm value) — read this parameter for the affected drive object; interpreted as a decimal number it gives the first alarm that has occurred for this drive object.
Acknowledging and restarting
A40103 requires no acknowledgement and the drive takes no automatic reaction to it. Resolving it means finding the alarm it points to: read the alarm value (r2124, decimal interpretation) and evaluate the alarm buffer of the affected drive object. How the alarm found there is cleared follows from its own entry.
The same on every family
Every manual that describes A40103 gives it the same reaction, acknowledgement and message class.

| G130, G150 | NONE | NONE | General drive fault (19) | None | SINAMICS G130, G150 List Manual · p. 1924 |

Questions technicians ask
What does SINAMICS alarm A40103 mean?
It reports that an alarm has occurred at the drive object at DRIVE-CLiQ socket X103. Its value is the first alarm that has occurred for this drive object, so it points to another alarm rather than naming a fault itself.
How do I find out which alarm is behind A40103?
Read the alarm value in r2124 and interpret it as a decimal number — it is the first alarm that has occurred for this drive object. Then evaluate the alarm buffer of the affected drive object.
Does A40103 have to be acknowledged?
No. No acknowledgement is required and the drive takes no automatic reaction to it. The action lies in the alarm it points to, which you find via the alarm buffer of the affected object.
In which parameter is the alarm value for A40103 stored?
In r2124, the alarm value of the drive object. Interpreted as a decimal number it gives the first alarm that has occurred for this drive object.
