Unless a point of intersection is found, the control will move,
at a right angle, to the end point of the previous interpolation.
If the compensation is canceled in a block in which no
movement is programmed in the selected plane, an offset
vector perpendicular to the end point of the previous
interpolation will be set and the compensation vector will be
deleted by the end of the next movement block.

If zero displacement has been programmed (or such is
obtained) in the block (G40) in which the compensation is
canceled, an offset vector perpendicular to the end point of
the previous interpolation will be calculated, and the control
will cover that instance in block G40. For example:
