What it means
A07590 signals that a Drive Data Set changeover (DDS) was requested while the drive was in "operation" mode, and that the data set being selected changes the mechanical relationships together with the encoder assignment of encoder 1 (p2502). A changeover of this scope is not carried out during operation; the drive signals the request with this alarm instead. Depending on the drive configuration, the same condition can also trip as a fault rather than an alarm.
Why it appears
- A Drive Data Set changeover (DDS) was requested while the drive was in "operation" mode, and the changeover changes the mechanical relationships and the encoder assignment (p2502).
What to check
- Exit the "operation" mode:
To changeover the drive data set, initially, exit the "operation" mode.
- Carry out the Drive Data Set changeover while the drive is outside "operation" mode, so the new mechanical relationships and the encoder assignment p2502 can be applied.
Parameters the manual names
- p2502 (LR encoder assignment): the alarm applies because the requested DDS changeover includes a change of this encoder assignment alongside the mechanical relationships.
Acknowledging and restarting
As an alarm, A07590 needs no acknowledgment and triggers no automatic stop reaction; it lapses once the changeover is performed outside "operation" mode as the remedy describes. If the drive is configured to raise the same condition as a fault instead, the drive reacts with OFF1 (OFF2, OFF3) and the fault must be acknowledged IMMEDIATELY.
The same on every family
Every manual that describes A07590 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2854 |
| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1588 |

Questions technicians ask
What does SINAMICS alarm A07590 mean?
It reports that a Drive Data Set (DDS) changeover was requested while the drive was in "operation" mode, and that this changeover changes the mechanical relationships and the encoder assignment (p2502) of encoder 1.
How do I clear A07590?
Exit the "operation" mode and carry out the Drive Data Set changeover there. As an alarm, A07590 requires no acknowledgment.
Does A07590 stop the drive?
As an alarm it triggers no automatic reaction. If the drive is configured to raise the same condition as a fault, it reacts with OFF1 (OFF2, OFF3) and the fault must be acknowledged IMMEDIATELY.
Which parameter is linked to A07590?
p2502, the LR encoder assignment: the alarm is issued when the requested changeover includes a change of this assignment together with the mechanical relationships.
