7-94
Function
Use this parameter when your servo is connected to an Allen Bradley 1394
digital drive. This parameter selects the 1394 drive axis module to which
the servo is connected. Each 1394 drive in your I/O ring can have up to
four amplifier axis modules (slots). They number from left to right, the
left most (closest to system module) being slot 0, the right most (furthest
from system module) being slot 3.
