The following parameter determines which CN1 pin (0 to 3 above) will be used to output the /BK signal.

Speed, torque,

Details
This parameter adjusts the delay time from /BK Signal Output until Servo OFF (stopping Servomotor output), and
it is used to be set when the machine moves slightly due to gravity or other factors after turning the brake ON.
This parameter is used to set the timing when the motor is stopped. Brake operation while the motor
is running is set in Pn507 and Pn508.
For the standard settings, the Servo will turn OFF simultaneously with the /BK output (Brake Opera-
tion). If gravity causes the machine to move slightly at this time due to machine configuration or
brake characteristics, turning OFF the Servo can be delayed to reduce the movement.
