•
Calculate the distance of travel according to the speed
limit, zero point return speed and deceleration speed,
and determine the movement amount after activation at
the near-point dog so that the distance of travel is larger
than the deceleration distance.
•
Set a smaller zero point return speed.
•
Adjust the near-point dog position so that the movement
amount after activation at the near-point dog becomes
longer. (Refer to sections 8.2.7 and 8.2.8)
