8-3-5 Circular Arc Interpolation (Intermediate Point Designated)

The following program positions a circle counter-clockwise with point C
[10,000, 10,000 (pulses)] as the intermediate point starting from the origin
[0,0 (pulses)] at 2 kpps. With intermediate point D [0, 10,000 (pulses)] inter-
polation proceeds to point C at 2 kpps. Without stopping, interpolation com-
pletes at the origin via intermediate point A [10,000, 0 (pulses)]. At the origin,
bit j+2 (15) turns ON to indicate completed positioning. For circular arc inter-
polation with a designated intermediate point, the entire circumference of a
circle cannot be produced because the center cannot be computed. Again,
acceleration and deceleration times are not used.
