MD26016 PUNCH_PARTITION_TYPE = 1
In contrast to the behavior described above, here the synchronous axis traverses the entire
programmed rotation path in the first sub-block of the selected path segmentation function.
Applied to the example, the C axis already reaches the programmed end position
when it reaches X position X = 15. It behaves in the same way in the circular interpolation
block below.
