What it means
Alarm A01318 (BICO: Deactivated interconnections present) signals that BICO interconnections belonging to deactivated drive objects are present or have been changed — for example after an inactive drive object has become active again. No protective response is triggered; the alarm stays until it is reset with p9496 or by deactivating the drive object again.
Why it appears
- An inactive or non-operational drive object has become active again or is ready for operation.
- There are items in the list of BI/CI parameters (r9498[0...29], r9499[0...29]).
- The BICO interconnections saved in the list of BI/CI parameters (r9498[0...29], r9499[0...29]) have actually been changed.
What to check
- Check whether an inactive or non-operational drive object has just become active again or is ready for operation.
- Check the list of BI/CI parameters (r9498[0...29], r9499[0...29]) for items and for BICO interconnections saved there that have actually been changed.
- Reset the alarm by setting p9496 to 1 or 2, or deactivate the drive object again.
Parameters the manual names
- p9496 — BICO behavior when activating drive objects: set it to 1 or 2 to reset this alarm.
Acknowledging and restarting
A normal acknowledgement does not remove this alarm. It is reset either by setting p9496 to 1 or 2 or by deactivating the drive object again; until one of these actions is carried out, the alarm remains present.
The same on every family

Questions technicians ask
What does SINAMICS alarm A01318 mean?
It reports that deactivated BICO interconnections are present: an inactive drive object has become active again, the BI/CI lists r9498[0...29] and r9499[0...29] contain items, or the BICO interconnections saved there have actually been changed.
How is A01318 reset?
Set p9496 to 1 or 2, or deactivate the drive object again. A normal acknowledgement does not clear the alarm.
Does A01318 stop the drive?
No. The drive triggers no protective response; the alarm only signals the interconnection state until it is reset via p9496 or by deactivating the drive object again.
