4.5.6 Electromagnetic brake wiring
If the servo motor is used to drive the vertical shaft, the electromagnetic brake can be used to prevent
against the falling of heavy objects or keep the falling speed when the servo drive is out of power. See
the following wiring diagram for the electromagnetic brake.

 You must provide independent 24V power for the electromagnetic brake, which cannot use the
signal-control power.
 In the figure,
RY
indicates relay coil. Pay attention to the diode direction.
 The electromagnetic brake is used for holding but not for common stop.
 Though the electromagnetic brake can prevent the falling of heavy objects or keep the falling
speed, you must install an external brake device.
