3.9 Magnet contactor control connector output (AXMC) for addition axes
When an additional axis is used, the servo ON/OFF status of the additional axis can be synchronized with the
servo ON/OFF status of the robot itself by using the output contact (AXMC) provided on the rear or inside of the
controller and configuring a circuit so that the power to the servo amplifier for the additional axis can be turned
off when this output is open.
An example circuit and an image of how to connect the controller connector are shown below. When you are using
an additional axis, please perform appropriate circuit connections by referring to these drawings.
Refer to the separate "Additional axis interface Instruction Manual" for details on the additional axis function.

Note1) you use the addition axis function as a user mechanism who became independent of the robot arm, please
do not connect this output signal. Servo-on of the user mechanism may be unable.
