Note 1. For the approximately 10 ms it takes from when the power to the Servomotor turns off until the
dynamic brake operates, the Servomotor rotates by momentum.
Note 2. If the motor rotational speed falls to 100 r/min or below, or if 500 ms elapse after power to the
Servomotor is interrupted, the brake interlock signal (BKIR) will turn OFF.
Note 3. The dynamic brake decelerates to stop the Servomotor when the RUN signal is OFF, alarm
output is ON, or power is turned off. The Servomotor will be in servo free condition with the
dynamic brake ON after the Servomotor stops rotating.
