Precautions for Correct Use of Holding Brake

The brake on a Servomotor with brake is a normally closed brake designed only to hold when
stopped.
Accordingly, set an appropriate time so that the brake will actuate after the motor stops.
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.

Set the time after a servo OFF command is issued upon
servo lock stop, until the brake interlock (BKIR) signal turns

Set the time after a servo OFF command is issued while the
motor is rotating, until the brake interlock (BKIR) signal
turns OFF and power supply stops. If the speed drops to 30
r/min or below before the time set here, BKIR will turn OFF.
