
RUN Command Timing (When Servomotor Is Stopped)
*1. The time from turning ON the brake power supply to the brake being released is 200 ms max.
Take this delay into account and be sure the brake has been released before providing a speed
command (pulse command).
*2. The time from turning OFF the brake power supply to the brake engaging is 100 ms max.
If using the Servomotor on a vertical axis, take this delay into account and set the Brake Timing
when Stopped (Pn6A) so that the Servomotor is deenergized after the brake has engaged.
*3. The Servo ON status will not occur until the Servomotor drops to 30 r/min or less.
 Power Supply OFF Timing (When Servomotor Is Stopped)
*1. The time from turning OFF the brake power supply to the brake engaging is 100 ms max.
If using the Servomotor on a vertical axis, take this delay into account and set the Brake Timing
when Stopped (Pn6A) so that the Servomotor is deenergized after the brake has engaged.
