The AXISCAL_ABS_POS item is used to read back the absolute
point locations from the axis calibration table. This item is read
only. Data points are added or removed using axis calibration
command items. Indexes for this item include:
point_num – this index identifies which point you are referencing.
Refer to your AMP reference manual for details. You can address
multiple points with one command. An error is returned if a point is
requested that does not exist for the specified axis. Use this item in
conjunction with AXISCAL_POINTS_USED.
axis_num – this index identifies the logical axis number for which
you are requesting axis calibration data. Axis numbers are
determined by your AMP configuration. You can only make
requests for one axis at a time. Use the axis number in this request.
Axis names are not valid.
AXISCAL_ABS_POS,1–34, 1
returns axis calibration absolute positions for points 1 thru 34 for
