3.4 Electromagnetic Brake
When motor drives the vertical axis, brake should be used to hold and prevent the work (moving
load) from falling by gravity while the power to servo is shut off.
NOTE: only use servo motor brake for hold the stalling status, i.e.. motor is in disable or
power off.
Never use this for “brake” purpose to stop the load in motion. Wrong use might cause
servo motor damage.

3.4.2 Notice for the Brake Motor
◆
When no power is applied to the electromagnetic brake, it is in locked position. Therefore, the
motor shaft will not be able to rotate.
◆
The brake coil has no polarity.
◆
During the brake/release action, there might be

sounds occurring, this does not
effect the use of brake.

In order to prevent damage to the brake, there are delay sequences during the brake operation.
Please be cautious with brake operation sequence.
