What it means
This alarm belongs to the EPOS positioning function. In the modes “traversing blocks” and “direct setpoint input/MDI”, the drive expects a 1 signal at the binector input “do not reject traversing task/reject traversing task” (BI: p2641) when a motion starts. The 1 signal tells the drive not to reject the traversing task; if it is missing at the start of motion, the drive raises A07487. The manuals describe the condition identically for every affected drive object, so the same explanation applies across the families.
Why it appears
- In the modes “traversing blocks” or “direct setpoint input/MDI”, the binector input “do not reject traversing task/reject traversing task” (BI: p2641) does not have a 1 signal at the start of motion.
What to check
- Connect a 1 signal to the binector input “do not reject traversing task/reject traversing task” (BI: p2641).
- Restart the motion.
Parameters the manual names
- p2641 — BI: EPOS reject traversing task (0 signal) / Trav_task reject: the binector input that must carry the 1 signal when motion starts in “traversing blocks” or “direct setpoint input/MDI” mode.
Acknowledging and restarting
No acknowledgement is required for this alarm. Once a 1 signal is connected to the binector input (BI: p2641) and the motion is restarted, the condition named in the remedy is resolved.
The same on every family
Every manual that describes A07487 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does alarm A07487 mean on a SINAMICS drive?
It belongs to the EPOS positioning function: at the start of motion in “traversing blocks” or “direct setpoint input/MDI” mode, the binector input “do not reject traversing task/reject traversing task” (BI: p2641) does not have a 1 signal.
How do I clear alarm A07487?
Connect a 1 signal to the binector input (BI: p2641) and restart the motion. The alarm does not have to be acknowledged.
Which parameter is involved in A07487?
p2641 — BI: EPOS reject traversing task (0 signal) / Trav_task reject. This is the input that must receive the 1 signal before the motion starts.
