Wiring and Connecting SERVOPACKs
* You can change the allocations. Refer to the following section for details.
6.2.1 Input Signal Allocations on page 6-3
Note: 1. Pin numbers in parentheses ( ) indicate signal grounds.
2. If forward drive prohibition or reverse drive prohibition is used, the SERVOPACK is stopped by software
controls. If the application does not satisfy the safety requirements, add external safety circuits as required.
