What it means
A07582 is the alarm the drive issues for Encoder 2: Position actual value preprocessing error
: an error has occurred while the drive preprocessed the position actual value of the second encoder — i.e. while it worked up the position signal of Encoder 2 into the actual value the drive uses. The manuals that describe the message (G130/G150 and S120/S150) state this same single cause, so there is no family-specific difference to watch for. Depending on the drive's configuration, the same condition can also be issued as the fault F07582 rather than as the alarm A07582.
Why it appears
- An error occurred during the position actual value preprocessing of Encoder 2 — this is the only cause the manuals print for this message; they do not break it down further.
What to check
- Check the encoder used for the position actual value preprocessing (Encoder 2). This is the remedy the manuals give for the message.
- Check the encoder assignment set in p2502 (LR encoder assignment): the manual for S120/S150 points to this parameter under the same remedy.
Parameters the manual names
- p2502 — LR encoder assignment: check which encoder is assigned here while working through the remedy for the Encoder 2 position actual value preprocessing error; the manual names this parameter for A07582.
Acknowledging and restarting
As an alarm, A07582 requires no acknowledgement. If the drive's configuration makes it signal the same condition as the fault F07582 instead, the drive stops with OFF1 (OFF2 and OFF3 are the reactions the manual also lists for this fault) and the fault must be acknowledged IMMEDIATELY. Once the encoder error has been remedied and the fault acknowledged, the drive can be restarted.
The same on every family
Every manual that describes A07582 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS S120, S150 List Manual · p. 2852 |
| G130, G150 | NONE | NONE | Actual position/speed value incorrect or not available (11) | Encoder 2 | SINAMICS G130, G150 List Manual · p. 1586 |

Questions technicians ask
What does SINAMICS alarm A07582 mean?
It reports an error during the position actual value preprocessing of Encoder 2 — the drive had a problem processing the position signal of the second encoder. Depending on the configuration, the same condition can also appear as the fault F07582.
How do I fix A07582?
Check the encoder used for the position actual value preprocessing; the S120/S150 manual also points to the encoder assignment in p2502 (LR encoder assignment). As an alarm no acknowledgement is needed; if it appears as fault F07582, acknowledge it IMMEDIATELY.
Does A07582 stop the drive?
As an alarm, no — it needs no acknowledgement. If the drive issues the same condition as the fault F07582, it stops with OFF1 (OFF2 and OFF3 are also listed) and must be acknowledged before the drive restarts.
Which drives can show A07582?
The manuals describe it for G130, G150, S120 and S150. It concerns the encoder configured as Encoder 2.
