10.6.6 Circular interpolation with intermediate point and end point (CIP, X... Y... Z..., I1...
J1... K1...)
CIP can be used 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 motion 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.
Syntax
