What it means
A01696 comes from the Safety Integrated motion monitoring (SI Motion). The drive raises it when the forced checking procedure — the test stop for the safe motion monitoring functions — is already selected at the moment the drive boots. Such a selection at boot is not permissible, and the consequence is that the forced check is only carried out again once the test stop has first been deselected and then selected again. The message does not result in a safety stop response. Depending on how the drive is configured, the same condition can also be issued as a fault instead of the alarm.
Why it appears
- The forced checking procedure (test stop) for the safe motion monitoring functions is already selected when booting, which is not permissible — for this reason the test is only carried out again after the forced checking procedure has first been selected.
What to check
- Look at the signal source with which the forced checking procedure is selected: it is set via binector input p9705, and at boot the test stop must not already be selected there.
- Deselect the forced checking procedure for the safe motion monitoring functions and then select it again, so that the drive carries out the test stop once more.
- Heed the manual's notice belonging to this remedy:
It is not permissible to use TM54F inputs to select the test stop.
Parameters the manual names
- p9705 (BI: SI Motion test stop signal source) — the binector input that sets which signal selects the forced checking procedure (test stop); this is where you deselect and re-select the test stop to clear the condition.
Acknowledging and restarting
As an alarm, A01696 does not call for a separate acknowledgement: the remedy itself — deselecting and then re-selecting the forced checking procedure via the signal source set in p9705 — puts the drive back into the permitted state, and the test stop is then carried out again.
If the drive issues the same condition as a fault instead, the manual attaches this note to the Safety Integrated message: Reaction upon F: NONE (OFF1, OFF2, OFF3); Acknowl. upon F: IMMEDIATELY (POWER ON)
.
What differs between the drive families
Straight from the manuals' own fields — A01696 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 2672 |
| G130, G150 | NONE | NONE | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1460 |
| G120 | NONE | NONE | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 850 |
The drives this code lives on
A01696 is described for G120, G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does alarm A01696 mean on a SINAMICS drive?
It is an SI Motion message: the test stop (forced checking procedure) for the safe motion monitoring functions was already selected when the drive booted, which is not permissible. The forced check is only run again after the test stop has first been deselected and selected again.
How do I clear A01696?
Deselect the forced checking procedure for the safe motion monitoring functions and then select it again. The selection is made via binector input p9705, and the manual explicitly forbids selecting the test stop through TM54F inputs.
Does A01696 trigger a safety stop response?
No. The manual states that this message does not result in a safety stop response.
What is p9705 used for with this alarm?
p9705 is the binector input that sets the signal source with which the forced checking procedure (test stop) is selected. It is the point where you deselect and re-select the test stop so that the drive runs the forced check again.
