Grinder Control Type is not available for Release 1 of 9/PC.
Use this data item to identify the absolute position of the skew slave
axis for a skew axis pair. The control supports two sets of skew axe
so the dimension of the skew_set array is two. For example:
SKEW_SLAVE_ABSOLUTE_POSITION, 1
would return the axis position of the skew slave axis for skew set 1.
Multiprocess systems still have a maximum of two skew axis total.
