Setting the pole and the angle reference axis
The pole is set by entering two Cartesian coordinates in one of the
three planes. These coordinates also set the reference axis for the
polar angle PA.
Absolute and incremental polar coordinates
Absolute polar coordinates always refer to the pole and the reference
axis.
Incremental coordinates always refer to the last programmed nominal
position of the tool.
