3.9 Additional Axis Function

This controller is equipped with an additional axis interface for controlling an additional axis when a traveling axis
or rotary table is added to the robot. A maximum of eight axes of servo motors can be controlled at the same time
by connecting a general-purpose servo amplifier (MR-J3-B, MR-J4-B series) that supports Mitsubishi's SSCNET
III.
Refer to the separate "Additional axis interface Instruction Manual" for details on the additional axis function.
