2. Circular interpolation using center point specification method
(1) Circular interpolation is performed from starting position to target position along the trajectory of the arc that takes the
distance to the specified center point position as radius.
(2) Movement direction is determined by the direction set in “PathChoice” of absolute position circular interpolation operation
(MC_MoveCircularAbsolute) or relative position circular interpolation operation (MC_MoveCircularRelative) motion
function block.
▪ 0: 「CW」 - Circular interpolation is executed from the starting position in a clockwise direction.
▪ 1: 「CCW」- Circular interpolation is executed from the starting position in a counterclockwise direction.
(3) If target position is same as start position, you can execute circular interpolation whose circle radius is distance
from center point to starting position.
