Requirements:
AUTOMATIC mode,
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1 = 0
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2 = 0
The control system inserts a traversing block at the step change point. This block generates
the smallest possible rotation to allow machining of the contour to continue.

Requirements:
AUTOMATIC mode,
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1 = 1 or 2
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2 = 1 or 2
The control system inserts a traversing block at the step change point. This block generates
the necessary rotation so that machining of the contour can continue on the same side of the
pole.
