Brake Timing When Stopped

Setting range 0 to 100
When the RUN Command Input is turned OFF while the Servomotor is stopped, the Brake Interlock
Signal (BKIR) will turn OFF, and the Servo will turn OFF after the time set for this parameter (setting
2 ms) elapses.
Make the setting as follows to prevent the machine (workpiece) from moving or falling due to the
delay in the brake operation (tb).

Dynamic Brake at Power OFF
By default, the dynamic brake of the Servo Drive will be engaged when the main
circuit power is turned OFF. For this reason, it feels slightly heavier to rotate the
Servomotor shaft manually than in servo free status. To release the dynamic
brake, disconnect the wirings (U, V, W) from the Servomotor. Be sure to
reconnect these wirings before restoring the power.
