As in N10, the collision monitoring is not yet active, the removal of the rapid input does not
stop the axes.
In N20, the collision monitoring is activated with G96. As chaining is active, the removal of
the rapid input stops the axes with the "deceleration at collision" specified for the
respective axis.
Upon selection of the rapid input, the axes are accelerated with the acceleration values
(MD 27).
If the rapid input is removed for a short time only, the axes will be braked with
"deceleration at collision". Then, traversing will be continued with the acceleration values
(MD 27).
In N30, the interpolation is switched on. When the rapid input is removed, the axes stop,
observing the interpolation conditions (the contour must not be left), i.e. the "deceleration
at collision" of the "weaker" axis (lower deceleration value) is taken into consideration as
the maximally admissible deceleration (in this case axis Y).
Upon selection of the rapid input, the axes are accelerated with the acceleration values
(MD 27).
If the rapid input is removed for a short time only, the axes will be braked with the
"deceleration at collision" of the "weaker" axis, observing the interpolation conditions.
Then, traversing will be continued with the acceleration values (MD 27).
