8.4.1 Hardware limit protection
D1 servo drive supports hardware limit protection. Hardware limit usually means the photoelectric switch
or micro switch installed on positioning platform to identify travel distance. Hardware limit switch is usually
a normally-closed sensor. When hardware limit switch is triggered, the servo drive decelerates the motor
by the value set for emergency stop (Dec. kill). At this time, the servo drive only accepts motion command
for moving the motor towards the opposite direction.
