The control uses the value selected for orientation to determine the
orientation of the grinding wheel when dresser/wheel radius compensation
is active. Enter the proper wheel orientation number (0-9) into the radius
offset table for the ORNT parameters. From that information, the control
can keep track of the orientation of the wheel, and prevent some
programming errors. Details on entering this information into the actual
offset table are described on page 3-11.
