What it means
A02095 reports that a multiple trace on trace recorder 0 (MTrace 0) cannot be activated, because a function or setting is combined with it that the drive does not permit there. The alarm names the possible conflicts itself: a measuring function, a long-time trace, and the trigger conditions IMMEDIATE (“immediate recording start”) and FG_START (“start with function generator”). The alarm text and its handling are the same on the G120, G130, G150, S120 and S150, and the alarm carries no message value.
Why it appears
- A measuring function is used together with the multiple trace on trace recorder 0.
- A long-time trace is used together with the multiple trace on trace recorder 0.
- The trigger condition is set to IMMEDIATE (“immediate recording start”).
- The trigger condition is set to FG_START (“start with function generator”).
What to check
- Find which of the settings listed under the causes is currently active alongside the multiple trace on trace recorder 0.
- If the multiple trace itself is not required, deactivate it by setting p4840[0] = 0.
- Otherwise keep the multiple trace and deactivate the function or setting that is not permissible with it.
Parameters the manual names
- p4840 — MTrace cycle number setting (cycle number): for this alarm it is the switch for the multiple trace; setting p4840[0] = 0 deactivates the multiple trace on trace recorder 0 and removes the conflict.
Acknowledging and restarting
The alarm needs no acknowledgement and the drive does not trip — it is purely a message about the trace configuration. Once p4840[0] = 0 has been set, or the impermissible function or setting has been deactivated, the condition that raised the alarm no longer exists.
What differs between the drive families
Straight from the manuals' own fields — A02095 is not described identically everywhere.
| 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. 2733 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1508 |
| G120 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 864 |
The drives this code lives on

Questions technicians ask
What does SINAMICS alarm A02095 mean?
It means that a multiple trace on trace recorder 0 (MTrace 0) cannot be activated because a measuring function, a long-time trace, or the trigger condition IMMEDIATE or FG_START is set together with it — none of these is permitted with a multiple trace.
How do I fix alarm A02095?
Either deactivate the multiple trace by setting p4840[0] = 0, or switch off the function or setting that is not permissible with the multiple trace. No acknowledgement is required.
Which parameter is behind A02095?
p4840, the MTrace cycle number setting. Setting p4840[0] = 0 deactivates the multiple trace on trace recorder 0.
Does A02095 stop the drive?
No. The alarm has no automatic reaction and needs no acknowledgement, so the drive keeps running; it only signals that the trace configuration as set cannot be used.
