Brake Timing when Stopped
Setting
0 to 10,000
range
Set the time required for the Servomotor to be de-energized (servo free) after the brake interlock
output (BKIR: CN1pin 10) turns ON (i.e., brake held), when servo OFF status is entered while the
Servomotor is stopped.
When the Servomotor is stopped and the operation command (RUN) is turned OFF, the brake
interlock signal (BKIR) will turn ON, and the servo will turn OFF after waiting for the setting time
(set value × ms).
Make the setting as follows to prevent the machine (workpiece) from moving or falling due to the
delay time in the brake operation (tb).
Brake timing when stopped (set value × 1 ms) ≥ tb

Pn438
Brake Timing during Operation
Setting
0 to 10,000
range
Set the required time 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. While the motor is operating and the operation command
(RUN) is turned OFF, the motor will decelerate to reduce rotation speed, and the brake interlock
signal (BKIR) will turn ON after the setting time (set value × 1 ms) has elapsed.
TB in the above figure is the brake timing during operation (set value × 1 ms) or the time until the
motor rotation speed falls to 30 r/min or lower, whichever is shorter.
For details, refer to "6-6 Brake Interlock" (P.6-20).
