4.3.4. Setting for Holding Brakes
The holding brake is used when the servodrive controls a vertical axis.
A servomotor with brake prevents the movable part from shifting due to gravity when the servodrive power
goes OFF. (Refer to
4.1.4 Trial Operation for Servomotor with Brakes. )
1. The brake built into the servomotor with brakes is a deenergization brake, which is used to hold and
cannot be used for braking. Use the holding brake only to hold a stopped servomotor.
2. When operating using only a speed loop, turn OFF the servo and set the input reference to 0 V when
the brake is applied.
1. Wiring Example.
Use the servodrive sequence output signal /BK and the brake power supply to form a brake ON/OFF
circuit.
The following diagram shows a standard wiring example.
