This chapter explains the grounding method of the actuator as well as the method to release
an electromagnetic brake.

Grounding the actuator
Since a grounding wire is included in the "cable for motor," you can ground it only to connect
with a driver. However, the grounding resistance value provided in the standards in which the
user applies to the equipment may not be satisfied depending on the type or length of the
"cable for motor." In this case, also ground the actuator Protective Earth Terminal.

48 VDC
Required
Ground if the grounding resistance of the standards that
applies to the equipment is not satisfied.
When multiple actuators are used in combination, connect each one to the
grounding point.
When connecting to the driver to ground the actuator:
1. Connect the "cable for motor" to the motor connector on the driver.
2. Ground the driver Protective Earth Terminal.
Be sure to ground the Protective Earth Terminal of the driver. Refer to the
AZ
Series
OPERATING MANUAL Driver for how to ground the driver.
Cable for motor
Connect the “cable for motor”
to the motor connector on the
driver.
