What it means
A02061 (Trace: Invalid signal) comes from the trace function: one of the signals selected for recording is not valid. Either the specified signal does not exist, or it can no longer be traced (recorded). The drive itself does not trip — the alarm only concerns the trace settings. Which signal each trace record captures is set in the trace record signal parameters p4730 to p4733.
Why it appears
- The signal specified for the trace function does not exist.
- The signal specified for the trace function can no longer be traced (recorded).
What to check
- Specify the signal to be traced: enter the intended signal in the trace record signal parameters p4730 to p4733.
- Check whether the relevant signal can be traced (recorded) by the trace function; if it cannot, specify a signal that can.
Parameters the manual names
- p4730 (Trace record signal 0): the signal selection for trace record 0 — check here which signal is specified and whether it exists and can be traced.
- p4731 (Trace record signal 1): the signal selection for trace record 1, checked the same way when this alarm appears.
- p4732 (Trace record signal 2): the signal selection for trace record 2, checked the same way when this alarm appears.
- p4733 (Trace record signal 3): the signal selection for trace record 3, checked the same way when this alarm appears.
Acknowledging and restarting
No acknowledgment is required for this alarm. The remedy is the correction itself: specify the signal to be traced in p4730 to p4733 and make sure that this signal can be traced (recorded).
What differs between the drive families
Straight from the manuals' own fields — A02061 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. 2731 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1506 |
| G120 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 863 |

Questions technicians ask
What does SINAMICS alarm A02061 mean?
The trace function has detected that a signal selected for recording does not exist or can no longer be traced (recorded). The drive itself does not trip.
How do I clear A02061?
No acknowledgment is required. Specify the signal to be traced and check whether the selected signal can be traced; the signal selection is made in p4730 to p4733.
Which parameters belong to A02061?
p4730 to p4733, the trace record signals 0 to 3. One of the signals specified there does not exist or cannot be recorded.
Does A02061 stop the drive?
No. The drive takes no automatic action for this alarm; it only signals that the trace signal selection is not valid.
