What it means
The function generator checks the speed setpoint of each drive it selects for connection. A02010 is raised when the speed setpoint of a drive selected for connection is greater than the value for the standstill detection set using p1226 — in other words, a connected drive does not deliver a zero speed setpoint. The G130, G150, S120 and S150 manuals describe the alarm identically.
Why it appears
- The speed setpoint of a drive selected for connection is greater than the value for the standstill detection set using p1226, so the drive does not report a zero speed setpoint.
What to check
- Determine all of the drives that are specified for connection to the function generator.
- Set the speed setpoints of these drives to zero.
Parameters the manual names
- p1226 — threshold for zero speed detection (standstill detection); for this alarm it is the value that the speed setpoint of a connected drive must not exceed.
Acknowledging and restarting
No acknowledgement is required and the drive takes no automatic action in response to this alarm. The alarm is reset by first removing its cause — the non-zero speed setpoints — and then restarting the function generator.
The same on every family
Every manual that describes A02010 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1500 |
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2726 |

Questions technicians ask
What does alarm A02010 mean?
The function generator has selected a drive for connection whose speed setpoint is greater than the standstill detection threshold set using p1226, so the drive's speed setpoint is not zero.
How do I clear A02010?
Set the speed setpoints of all drives specified for connection to zero, then restart the function generator once the cause has been removed.
Does A02010 have to be acknowledged?
No. The alarm takes no automatic action on the drive and needs no acknowledgement; it is reset by removing the cause and restarting the function generator.
Which parameter is linked to A02010?
p1226, the threshold for zero speed detection. The alarm appears when a connected drive's speed setpoint is greater than this value.
