Set these parameters when the tool axis and tool rotation axis do not intersect.
These parameters are valid when parameter No. 19680 is set to 2 or 21.
If parameter No. 19680 is 21, set the vector from point D on the tool axis to point E
determined on the tool rotation axis as the intersection offset vector in the machine
coordinate system when the rotation axes for controlling the tool are all at 0 degrees.
If parameter No. 19680 is 2, set the vector from point D on the tool axis to point E
determined on the second rotation axis of the tool as the intersection offset vector in
the machine coordinate system when the rotation axes for controlling the tool are all
at 0 degrees.

NOTE
Point D is determined by adding the tool length offset and tool holder
offset (parameter No. 19666) to the tool tip.
As point E, set a position that is easy to measure.
