What it means
The alarm reports that, in the multi-pump control, the technology controller system deviation r2273 has exceeded the threshold p29546 at a moment when all motors of the system are running — the only motors not running are those that are under service or locked.
Why it appears
- The technology controller system deviation r2273 has risen above the threshold set in p29546.
- At the same time, all motors are running; the only exceptions are motors that are under service or locked.
What to check
- Determine whether any motors in the system are under service or locked, and repair or unlock them.
- Check the number of motors in the system; if it is less than four, add more motors to the system.
Parameters the manual names
- r2273 (CO: technology controller system deviation) — the value this alarm monitors against the p29546 threshold.
- p29546 (multi-pump control deviation threshold) — the limit that r2273 must stay below; the alarm is signalled once r2273 exceeds it.

Questions technicians ask
What does alarm A52963 mean in the SINAMICS G120XA?
It signals that the technology controller system deviation r2273 has exceeded the threshold p29546 while all motors are running, apart from motors that are under service or locked.
How is A52963 remedied?
Repair or unlock any motors that are under service or locked. If the system contains fewer than four motors, add more motors to the system.
Which parameters belong to A52963?
r2273 holds the technology controller system deviation and p29546 sets the multi-pump control deviation threshold; the alarm appears when r2273 exceeds the p29546 value.
