8-4-2 Circular Arc Positioning
In this example, the center is already determined, but the digital switches de-
termine the arc radius. The center has been determined at (2,500, 2,500).
Set the radius with the digital switches. The axes then construct the pre-
scribed circle starting at the origin and returning to the origin at a speed of 1
pps.
