Description
Unless otherwise specified, the reference coordinate for the
alignment of the workpiece is always the abscissa of the selected
plane. *
=0: Reference coordinate is the abscissa
=1: Reference coordinate is the ordinate
Unless otherwise specified, the workpiece position angle is
entered in the frame as a rotation. Otherwise, a channel axis index
can be specified for a rotary axis whose translation is set to the
current rotary axis position plus the calculated rotation. The
workpiece is then aligned at rotary axis position = 0. The current
rotary axis value must be set in $AA_MEAS_POINT[axis]. *
