Additional Axis Function
3 Controller
3.8 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.
3.8.1 Wiring of the Additional Axis Interface
Table 3-8 shows the connectors for additional axes inside the controller. Fig. 3-22 (CR750) and Fig. 3-23 (CR751)
shows a connection example (configuration example).
