Circular interpolation with intermediate and end points (CIP)

You can use CIP to program arcs. These arcs can also be inclined in space. In this case,
you describe the intermediate and end points with three coordinates.
The circular movement is described by:
• The intermediate point at addresses I1=, J1=, K1= and
• the end point in Cartesian coordinates X, Y, Z.
The traversing direction is determined by the order of the starting point, intermediate point
and end point.

4.10 Circular interpolation with intermediate and end points (CIP)
Circular interpolation through intermediate point
End point in Cartesian coordinates. These data depend on the motion
commands G90/G91 or ...=AC(...)/...=IC(..)
Circle center point in Cartesian coordinates (in X, Y, Z direction)
The identifiers have the following meanings:
I: Coordinate of the circle center point in the X direction
J: Coordinate of the circle center point in the Y direction
K: Coordinate of the circle center point in the Z direction

Incremental dimensions (non-modal)
