6. Helical interpolation
(1) When circular interpolation commands (absolute position coordinate system circular interpolation operation (MC_
MoveCircularAbsolute2D), relative position coordinate system circular interpolation operation (MC_MoveCircularRelati
ve2D)) are executed, circular interpolation is performed by moving in a circular trajectory on the XY plane, while li
near interpolation synchronized to the circular interpolation motion is performed with respect to Z-axis
(2) To perform helical interpolation, set the target position for linear interpolation at Pz of ‘EndPoint’.
