You can change the allocations. Refer to the following section for details.
5.19.1 Input Signal Allocations
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.
