Motor holding brake

A holding brake is used to hold the position of the servo motor when the motor power is cut
off. The servo motor can move because of its own weight or an external force even the
motor power has been cut off.
The holding brake is built in the servo motor with brakes.
Note
• The brake built in the servo motor with brakes is a de-energization brake. It is used only
to hold the servo motor and cannot be used for motor braking. Use the holding brake only
to hold a stopped motor.
• The holding brake is activated at the same time when the motor power is cut off.
• Refer to Section "System connection (Page 63)" for the standard wiring of the holding
brake.
