Magnet Contactor Control Connector Output (Axmc) For Addition Axes; Example Circuit - Mitsubishi Electric CR750-D Instruction Manual

Magnet contactor control connector output (AXMC) for addition axes

2.2.10
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.
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.

[Note] In the customer's system, do not ground the + side of 24V power supply prepared by customer for connect to the
controller. (related with emergency stop and parallel input/output) If it connects with the controller under the condition
that the + side is grounded, it will lead to failure of controller.
