2) If the goal position is same as starting position, it is available to have an operation like a circle that has distance
from starting point to auxiliary point as its radius

3) Control unit “degree” is not available to be used for circular interpolation control.
4) Direction is determined in setting of “Cir int. mode” (Center point CW, Center point CCW).
(c) Circular interpolation with radius designation form
1) Starts operating from starting position and execute circular interpolation along trace of circular arc that has
value designated in auxiliary point of main axis as it radius. Depending on size setting of circular
arc(<180°,>=180°), center point of circular arc will be different.
2) In radius designation form, goal position can’t be set the same as starting position.
3) Control unit “degree” is not available to be used for circular interpolation control.
4) The direction and arc size are determined in “Cir. int. mode”.
