What it means
The drive raises A02030 when the physical address configured for the function generator equals zero. That address is held in p4812, and a value of zero there is not permissible. The alarm remains present until the address is corrected and the function generator is restarted. It triggers no automatic drive reaction and does not have to be acknowledged.
Why it appears
- The physical address specified for the function generator has the value zero (parameter p4812).
What to check
- Check the function generator physical address in p4812 and confirm whether it currently contains zero.
- Set a physical address with a value other than zero in p4812.
Parameters the manual names
- p4812 — function generator physical address (FG phys address): this is the parameter to correct for A02030; enter a value other than zero here, then restart the function generator.
Acknowledging and restarting
The manual prescribes the reset in two steps: The alarm is reset as follows: - remove the cause of this alarm. - restart the function generator.
In practice this means that once p4812 holds a non-zero physical address, the function generator is restarted and the alarm clears; no fault acknowledgement is required for this alarm.
The same on every family
Every manual that describes A02030 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2728 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1503 |

Questions technicians ask
What does alarm A02030 mean on a SINAMICS drive?
It means the physical address configured for the function generator is zero. The address is held in p4812 and must be a value other than zero.
How do I clear A02030?
Set a physical address with a value other than zero in p4812, then restart the function generator. No acknowledgement is needed; the alarm resets once its cause is removed.
Which parameter belongs to alarm A02030?
p4812, the function generator physical address. Correcting this parameter and restarting the function generator removes the alarm.
Does A02030 stop the drive?
No. The alarm triggers no automatic reaction; it only signals that p4812 still contains zero.
