Precautions for Correct Use of Holding Brake
Œ
The brake on a Servomotor with brake is a non-excitation brake designed only to hold when
stopped.
Accordingly, set an appropriate time so that the brake will actuate after the motor stops.
Œ
If the brake is applied while the Servomotor is rotating, the brake disc will wear abnormally or
sustain damage, resulting in a bearing or encoder failure in the Servomotor.
