Set these parameters when the tool axis does not intersect with the tool pivot.
This parameter becomes effective at parameter No.19680=21.
Set the value in the machine coordinate system of the vector to point E on the
tool pivot from point D on the tool axis when the positions of all rotary axes are 0
degrees.
Note
1. Point D becomes a position in which the tool length offset and the tool holder offset
(parameter No.19666) were tempered from the tool center point. Please set the
position on the table axes measured easily as point E.
2. Please set this parameter by the radius value.
3. The value on Cartesian coordinates has to be set when angular axis control is
available.
