What it means
A07825 is raised when simulation mode is activated on the drive (parameter p1272). It appears as an alarm; depending on the drive configuration, the same condition can also be reported with no reaction (N). While simulation mode is active, the drive can only be switched on if the DC link voltage is less than 40 V. The alarm carries no message value and clears by itself once simulation mode is switched off.
Why it appears
- Simulation mode is activated (p1272).
What to check
- The manual states that no remedy is necessary for this alarm.
- If simulation mode should not be active, deactivate it by setting p1272 = 0.
- The alarm then disappears automatically, without acknowledgement.
Parameters the manual names
- p1272 — Simulation mode: set p1272 = 0 to deactivate simulation mode; the A07825 alarm is then withdrawn automatically.
Acknowledging and restarting
No acknowledgement is required. The alarm is withdrawn automatically as soon as simulation mode is deactivated with p1272 = 0.
The same on every family
Every manual that describes A07825 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS G130, G150 List Manual · p. 1600 |
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 2868 |

Questions technicians ask
What does A07825 mean on a SINAMICS drive?
Simulation mode is activated on the drive. While it is active, the drive can only be switched on if the DC link voltage is less than 40 V.
How do I clear alarm A07825?
You do not have to acknowledge it. The alarm is withdrawn automatically as soon as simulation mode is deactivated with p1272 = 0.
Why does my drive refuse to switch on while A07825 is active?
In simulation mode, switch-on is only possible when the DC link voltage is less than 40 V. Deactivate simulation mode (p1272 = 0) for normal operation.
Is A07825 a fault or an alarm?
It is issued as an alarm; depending on the drive configuration, the same condition can also be reported with no reaction (N).
