What it means
A01507 is raised when BICO interconnections are still configured to a drive object that is currently inactive or inoperable — for example because a component has been removed or has not been activated again. The message therefore points to open signal interconnections between drive objects rather than to a problem inside one object. The manuals for the G130, G150, S120 and S150 describe it identically. Depending on how the drive is configured, the same condition can also be output as a fault or with no reaction at all.
Why it appears
- BICO interconnections still point to a drive object that is inactive or not operational — for instance after components have been removed or have not been re-inserted and activated again.
What to check
- Read the message value: it states the number of BICO interconnections that were found to inactive drive objects (on the G130/G150 in r2124, to be interpreted as a decimal number).
- Open r9498 to see the BI/CI parameters involved and r9499 for the associated BO/CO parameters; note that these two lists are only written if p9495 is not set to 0.
- In the deactivated drive object itself, display r9491 and r9492 — they show the list of its BICO interconnections to other drive objects.
- If the drive object is to remain part of the configuration, make it operational again: re-insert or activate the components.
- If the interconnections are no longer wanted, set p9495 = 2; this resets all open BICO interconnections centrally to the factory setting.
Reading the message value
- The value gives the number of BICO interconnections found to inactive drive objects.
- The G130/G150 manual specifies this value as the alarm value in r2124 and says to interpret it as a decimal number.
Parameters the manual names
- r9491 — displayed in the deactivated drive object; shows the BI/CI parameters of its BICO interconnections to other drive objects.
- r9492 — displayed in the deactivated drive object; shows the BO/CO parameters of its BICO interconnections to other drive objects.
- p9495 — set to 2 here to reset all open BICO interconnections to inactive drive objects centrally to the factory setting; note that r9498 and r9499 are only written while p9495 is not 0.
- r2124 — alarm value of this message: the number of BICO interconnections found to inactive drive objects, read as a decimal number.
Acknowledging and restarting
As an alarm, A01507 needs no acknowledgement and the drive keeps running; what matters is removing the condition itself. Either set p9495 = 2 to clear the open interconnections, or make the non-operational drive object active again. If the drive is configured to output this condition as a fault instead, the affected drive object is switched off (OFF2) and the fault must be acknowledged immediately.
The same on every family
Every manual that describes A01507 gives it the same reaction, acknowledgement and message class.
| 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. 2614 |
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1424 |

Questions technicians ask
What does SINAMICS alarm A01507 mean?
It means BICO interconnections are still configured to a drive object that is inactive or inoperable, for example after a component was removed or not reactivated. The message value tells you how many such interconnections were found.
How do I clear A01507?
Either set p9495 = 2, which resets all open BICO interconnections centrally to the factory setting, or make the non-operational drive object active again by re-inserting or activating its components. As an alarm the message itself needs no acknowledgement.
Where can I see which BICO interconnections are affected by A01507?
r9498 lists the BI/CI parameters involved and r9499 the associated BO/CO parameters (written only while p9495 is not 0); r9491 and r9492 in the deactivated drive object show its interconnections to other drive objects.
Does A01507 stop the drive?
No — as an alarm it has no reaction and the drive keeps running. Only if the drive is configured to output the condition as a fault is the drive object switched off (OFF2), and the fault must then be acknowledged immediately.
