Depending on the dynamic response of all the axes involved, the linear
relation cannot always be established before the lift position is reached.

In the case of geometry axes, the assigned value is
interpreted as a position in the workpiece coordinate
system. In the case of machine axes, it is interpreted as a
position in the machine coordinate system.
The values assigned can also be programmed as
incremental dimensions:
