7.6.2 Using the Holding Brake
The holding brake is used when a servodrive controls a vertical axis. In other words, a servomotor with brake
prevents the movable part from shifting due to gravity when system power goes OFF.
The brake built into the SGM S servomotor with brakes is a de-energization brake, which is used only to
hold and cannot be used for braking. Use the holding brake only to hold a stopped servomotor. Brake torque
is at least 120% of the rated motor torque.
(1) Wiring Example
Use the SERVOPACK sequence output signal /BK and the brake power supply to form a brake ON/OFF circuit.
The following diagram shows a standard wiring example.
This output signal controls the brake when using a servomotor with a brake and does not have to be connected
when using a servomotor without a brake.
