What it means
This alarm is raised by the EPOS positioning function when a motion is started in the 'traversing blocks' or 'direct setpoint input/MDI' mode while the binector input 'no intermediate stop/intermediate stop' (BI: p2640) does not carry a 1 signal. The parameter is designated 'EPOS intermediate stop (0 signal)': the intermediate stop is commanded with a 0 signal, which is why the drive expects a 1 signal at the start of motion.
Why it appears
- A motion start was issued in the 'traversing blocks' or 'direct setpoint input/MDI' mode while the binector input 'no intermediate stop/intermediate stop' (BI: p2640) did not have a 1 signal.
What to check
- Connect a 1 signal to the binector input 'no intermediate stop/intermediate stop' (BI: p2640).
- Re-start motion with the 1 signal present at BI: p2640.
Parameters the manual names
- p2640 — binector input (BI) 'EPOS intermediate stop (0 signal)' / 'Intermediate stop': the input that must carry the 1 signal at the start of motion and to which the remedy points.
Acknowledging and restarting
The manual describes no acknowledgement action for this alarm. Its remedy ends with re-starting the motion once the 1 signal is connected at BI: p2640; no further reset step is given.
The same on every family

Questions technicians ask
What does SINAMICS alarm A07486 mean?
It is the EPOS alarm 'Intermediate stop missing': at the start of motion in 'traversing blocks' or 'direct setpoint input/MDI', the binector input 'no intermediate stop/intermediate stop' (BI: p2640) did not have a 1 signal.
How do I clear alarm A07486?
Connect a 1 signal to the binector input 'no intermediate stop/intermediate stop' (BI: p2640) and re-start motion. The manual describes no additional acknowledgement step.
Which parameter is linked to A07486?
p2640, the binector input (BI) 'EPOS intermediate stop (0 signal)'. Because the intermediate stop is commanded with a 0 signal, the drive expects a 1 signal when motion starts.
In which operating modes does A07486 appear?
In the EPOS modes 'traversing blocks' and 'direct setpoint input/MDI'. The signal at p2640 is evaluated at the start of the motion.
