6.8.4 Output timing of BK signal when motor is operating
If an alarm occurs when servo motor is operating, the servo motor will stop and BK signal will be OFF.
Use Pt507 (Brake command output velocity value) and Pt508 (Servo off-brake command waiting time) to
adjust the output timing of BK signal. When one of the settings in Pt507 and Pt508 is satisfied, BK signal
will be output. Refer to figures 6.8.4.1 and 6.8.4.2.
Note:
If the motor stopping method for alarm is to stop the motor with zero velocity, the operation will follow the setting of
Pt506 (Brake command-servo off delay time) after the motor stops.
