• Set the required time for the Brake Interlock Output (BKIR) to turn OFF after the operation command
(RUN) is detected to be OFF, when servo OFF status is entered while the Servomotor is operating.
When the servo is turned OFF while the Servomotor is operating, the motor decelerates to reduce
rotation speed, and the brake interlock output (BKIR) turns ON after the set time (set value × 1 ms)
has elapsed.
The time T
B in above drawing is either the brake timing during operation (i.e., the set value × 1 ms) or
the time taken until it goes below the value set in the Brake Threshold Speed During Operation
(3439 hex), whichever is shorter.
• For the operation time, refer to 7-5 Brake Interlock on page 7-15.
• Set the required rotation speed for the Brake Interlock Output (BKIR) to turn OFF after the servo OFF
command is detected while the Servomotor is operating.
• For the operation time, refer to 7-5 Brake Interlock on page 7-15.
