What it means
A02062 tells you that the signal configured to trigger the trace is not usable, so the trace cannot be triggered in its current configuration. The trigger signal is specified in p4711 (Trace trigger signal). The message applies to all drive objects, and the drive itself does not intervene in operation — it only signals that the trace configuration has to be corrected.
Why it appears
- No trigger signal has been specified at all.
- The signal that is specified does not exist.
- The specified signal is not a fixed-point signal.
- The specified signal is not permitted as a trigger signal for the trace.
What to check
- Open p4711 (Trace trigger signal) and check whether a trigger signal is specified there at all.
- Check that the specified signal actually exists.
- Check that the specified signal is a fixed-point signal.
- Check that the signal is permitted as a trigger signal for the trace.
- Specify a valid trigger signal in p4711.
Parameters the manual names
- p4711 (Trace trigger signal / Trace trig_signal): the parameter in which the signal that is to trigger the trace is specified — this is where you check and set the valid trigger signal for this alarm.
Acknowledging and restarting
This alarm does not have to be acknowledged. As soon as a valid trigger signal has been set in p4711, the trace can be triggered again; no reset of the drive is required for this message.
What differs between the drive families
Straight from the manuals' own fields — A02062 is not described identically everywhere.
| 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. 1506 |
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2732 |
| 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 alarm A02062 in SINAMICS mean?
It means the trigger signal configured for the trace function is invalid: either none was specified, the signal does not exist, it is not a fixed-point signal, or it cannot be used as a trigger signal for the trace.
How do I fix SINAMICS alarm A02062?
Specify a valid trigger signal in p4711 (Trace trigger signal). Check that the signal exists, is a fixed-point signal and is permitted as a trace trigger signal.
Does A02062 stop the drive or need an acknowledgment?
No. The drive takes no action in response, and the alarm does not have to be acknowledged — once a valid trigger signal is set, the trace can be triggered again.
Which parameter belongs to alarm A02062?
p4711, the Trace trigger signal. This is the parameter in which the trigger signal is specified whose invalid configuration raises the alarm.
