You can change the allocations. Refer to the following section for details.
7.1.1 Input Signal Allocations on page 7-4
Note: If forward drive prohibition or reverse drive prohibition is used, the SERVOPACK is stopped by software con-
trols. If the application does not satisfy the safety requirements, add external safety circuits as required.

General-purpose
Sequence Input 1 (For-
ward Drive Prohibit Input)
You can allocate the input signal to use
with a parameter.
(Stops Servomotor drive (to prevent over-
travel) when the moving part of the
machine exceeds the range of move-
ment.)
