What it means
A07352 tells you that the limit switch signals the drive evaluates are not plausible. The drive takes these signals from the BICO interconnections stored in p3342 (limit switch plus) and p3343 (limit switch minus). On the G115D the manual lists the same code as Stop sensor not plausible
and names only checking the sensors as the remedy.
Why it appears
- The BICO interconnections for the limit switch signals (p3342, p3343) are not OK.
- The sensors are not supplying a valid signal: both supply a 0 signal at the same time.
What to check
- Check the BICO interconnections for the limit switch signals — p3342 (limit switch plus) and p3343 (limit switch minus).
- Check the sensors; the alarm points at a state in which both sensors supply a 0 signal instead of a valid one.
Parameters the manual names
- p3342 — BI: Limit switch plus. This is the BICO interconnection of the plus limit switch signal to be checked for this alarm.
- p3343 — BI: Limit switch minus. This is the BICO interconnection of the minus limit switch signal to be checked for this alarm.
Acknowledging and restarting
The manual specifies no acknowledgment for this alarm, so there is no reset step to perform. The remedy is the fix itself: once the BICO interconnections p3342 and p3343 are checked and the sensors again deliver a valid signal instead of two simultaneous 0 signals, the limit switch signals are plausible and the alarm condition is gone.
What differs between the drive families
Straight from the manuals' own fields — A07352 is not described identically everywhere.

Questions technicians ask
What does alarm A07352 mean in a SINAMICS drive?
The drive reports that the limit switch signals are not plausible. Either the BICO interconnections in p3342 and p3343 are not OK, or both sensors are supplying a 0 signal at the same time.
How do I fix alarm A07352?
Check the BICO interconnections for the limit switch signals (p3342 limit switch plus, p3343 limit switch minus) and then check the sensors. No acknowledgment is required; the alarm ends when the signals are plausible again.
Why are both limit switch signals 0 a problem?
The manual describes sensors that are not supplying a valid signal as both supplying a 0 signal, and the drive evaluates this combination as not plausible.
What is A07352 on a G115D?
The G115D manual lists the code as <q>Stop sensor not plausible</q> and names only checking the sensors.
