(2) Radius specified circular interpolation, incremental coordinate
(
「
Incremental, Circular interpolation
」
)
(a) Starts operation from starting position and executes circular interpolation by the increment set on target
position along the trace of the circle which has the value set on circular interpolation auxiliary point of main-
axis operation data as a radius. Circular arc depends on the moving direction of

(CW, CCW) and setting of arc size(Arc<180°, Arc>=180°)
Circular interpolation mode Description
Radius, CW, Arc<180°
Executes circular interpolation with center-point whose arc is smaller than
180° in CW direction
Radius, CW, Arc >=180°
Executes circular interpolation with center-point whose arc is bigger than 180°
in CW direction
Radius, CCW, Arc<180°
Executes circular interpolation with center-point whose arc is smaller than
180° in CCW direction
Radius, CCW, Arc>=180°
Executes circular interpolation with center-point whose arc is bigger than 180°
in CCW direction
