• Set the time required for the Brake Interlock Output (BKIR: CN1 pin 10) to turn OFF after the
Operation Command (RUN: CN1 pin 29) is detected to be OFF, when servo OFF status is entered
while the Servomotor is operating.
When the Operation Command (RUN) turns OFF while the Servomotor is operating, the motor
decelerates to reduce rotation speed, and the Brake Interlock Output (BKIR) turns ON after the set
time (set value x 1 ms) elapsed.
