12.32.8 Reduction zone of a protection zone
Each coordinate of a protection zone that is assigned a motion axis has a reduction zone in
this coordinate. The reduction zone is the distance around the protection zone within which it
is only possible to traverse with a speed proportional to the distance from the protection zone.
The size of the reduction zone is equal to the maximum braking distance of the motion axis of
the coordinate.
