Parameter Details
Set the time required for the Servomotor to be de-energized (servo free) after the brake interlock
output (BKIR: CN1 pin 10) turns OFF (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 OFF, and the Servomotor will be de-energized 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
For details, refer to "6-6 Brake Interlock" (P.6-19).
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. When the operation command (RUN) is turned OFF while the
motor is operating, the motor will decelerate to reduce 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 (Pn438) (set value × 1 ms) or the
time until the motor rotation speed falls to the speed set for the Brake Release Speed Setting
(Pn439) or lower, whichever is shorter.
For details, refer to "6-6 Brake Interlock" (P.6-19).
