Special instances of offset mode:
If zero displacement is programmed (or such is obtained) in the selected plane in a block in offset
mode, a perpendicular vector will be positioned to the end point of the previous interpolation, the
length of the vector will be equal to the radius compensation. Instances of this kind should be
handled with caution because of the hazards of inadvertent undercutting or distortions (in the case of
a circle).
