Important: The configuration of the 8520 digital servo module output
ports with the 8520 digital servo amplifier connectors will vary depending
on the AMP configuration of the system. Refer to the 9/Series CNC 9/230,
9/260, and 9/290 AMP Reference Manual, publication 8520-6.4, for more
information.
There are three 8520 digital servo amplifier options available. These can
be connected in any combination to drive up to nine digital servo axes
(9/290). Configurations should be based on motor size and take into
consideration the per axis rated current limitations of each amplifier.
Table 13A.A lists the 8520 digital servo amplifier options and their
corresponding specifications.
