4.6 Using an electromagnetic brake
Servo motors are used in loads such as vertical axes. When the motor is not enabled or powered
o󰀨, in order to prevent the mechanical mechanism driven by the motor from falling due to gravity
and other reasons, it is necessary to use a servo motor with an electromagnetic brake.
Note: The brake of the servo motor can only be used to maintain the position of the motor when
the motor is not enabled or powered o󰀨. Do not use it as a brake during deceleration, otherwise the
motor will be damaged.

4.6.2 Precautions for the use of brake motors
• The special output interface of the driver to control the brake can directly drive the brake of the
motor, and the auxiliary power supply must be connected to provide 24VDC.
• The electromagnetic brake is a normally closed type, and the motor shaft cannot rotate without
power supply to the brake.
• The brake will make a clicking sound during the braking / release action, which will not a󰀨ect
the use.
• It is recommended to use a cable of 0.5mm 2 (AWG20) or more to prevent the cable from
being too thin and causing voltage drop.
