3.8 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 is shown in
in Page 88, "(2) Image of how to connect the controller
When you are using an additional axis, please perform appropriate circuit connections by referring to these draw -
ings.
Refer to Page 83, "3.7 Additional Axis
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.

(1) Example circuit

1) Get the power supply for the controller from the secondary terminal of short circuit
breaker (NV) built in the addition axis amplifier box.
2) Get the power supply for the MC synchronization from the secondary
terminal of short circuit breaker (NV) prepared by the customer.
NV
To the internal
circuit
AXMC is output
from the contact
for internal servo
power supplies.
[Note] For the input/output cable (CNUSR connector cable) that connects customer's system and the controller, prevent
ground faults from occurring at the + side of the 24V power supply prepared by customer. A ground fault may lead to a
failure of the protection device in the controller.
Bending or frictional forces may be applied to the input/output cable repeatedly depending on the system configuration
or layout. In this case, use a flexible cable for the input/output cable. Note that a fixed cable may be broken, resulting in
a ground fault.
