If a rotary axis is to turn by 180 degrees or the contour for CP passes through the pole,
rotary axes depending on the machine data
turned by -/+ 180 degrees and traversed in clockwise or counter-clockwise direction. It can
also be set whether traversal is to go through the pole or whether rotation around the pole is
to be performed.
