4.3.3 Circular interpolation control with sub point designated

2-axis control with ABS circular interpolation (absolute system)

(1) Circular interpolation is curried out from the current address (address before

positioning), which is specified based on the OP, to the end point address through

the designated sub point address.

(2) The path that the positioning operation draws results in an arc whose center point

is an intersection point of two perpendicular bisectors, one of which is a straight

line between the start point address (current stop position) and sub point address,

and the other of which is a straight line between the sub point address and end

point address.
