Precautions for Correct Use of Holding Brake
 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.
