Precautions for Correct Use Precautions for Correct Use
• The brake on a Servomotor with a brake is a normally closed brake designed only to hold
when the operation is stopped. Accordingly, set an appropriate time so that the brake actuates
after the motor stops.
• If the brake is engaged while the Servomotor is rotating, the brake disc will wear abnormally or
sustain damage, resulting in a bearing or encoder failure in the Servomotor.
• The workpiece may fall when the brake is released for a vertical axis. Carefully consider the
timing of releasing the brake.
