The linear interpolation to other linear axis is executed performing 2 axes circular
interpolation from current stop position (X

executed so that it may become a spiral course.
It goes around on the specified circle for the specified number of pitches, the circular
interpolation which had remainder specified is executed, and positioning to end
address is executed. The central point-specified circle specifies circular interpolation
method connected start point and end point at the seeing on the plane for which
performs circular interpolation.
Operation details for absolute central point-specified helical interpolation are shown
