The following parameter determines which CN1 pin (0 to 3 above) will be used to output the /BK signal.
Parameter Name Unit Setting/Range Default Control Mode
Pn506 Brake ON Timing after Motor Stops 10 ms 0 to 50 0
Speed, torque,
position control
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.

Pn507: Speed Level for BK Signal Output when Motor Running
Pn508: Timing of BK Signal Output when Motor Running
These settings are used to set the timing for applying the brake when the Servo turns OFF due to an /S-ON input signal or alarm.

The brake on the Servomotor is
designed as a holding brake and it
must be applied only after the motor
has stopped. Adjust this parameter
while observing machine operation.
