Set the required time for the Brake Interlock Output (BKIR) to turn OFF after the motor is de-
energized, when servo OFF status is entered while the motor is operating.
•
When the servo is turned OFF while the motor is operating, the motor decelerates to reduce speed,
and the brake interlock output (BKIR) turns ON after the set time (set value x 1 ms) has elapsed.
*1
The time TB 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 timing, refer to
