1.1.9 Cautionary Items on Servomotor Equipped with a Brake
Brake noise
The brake lining may issue chattering noise during operation of the motor equipped with a brake. As
1
it is caused by brake structure and is not abnormal, the noise will not effect functional operation.
Others (shaft end magnetization)
The shaft end of the servomotor equipped with a brake is subject to leaking magnetic flux during
energization of the brake coil (when the brake is released). At the instance, chips, screws and other
magnetic bodies will be attracted. Cautions are required.
The servomotor equipped with a brake may produce brake dust due to the brake timing shift
generated between ON and OFF. Therefore when installing the motor to the machine, it is
recommended to install the motor horizontal to the machine or under the shaft.
