4. DESCRIPTION OF PARAMETERS
B–63010EN/02

NOTE
Select a local coordinate system setting operation when
cutter compensation is applied, and when two or more
blocks specifying no movement exist prior to the
specification of G52, or when G52 is specified after cutter
compensation mode is canceled without eliminating the
offset vector.

This is one of the parameters that give the position of the origin of
workpiece coordinate system (G54 to G59). It gives an offset of the
workpiece origin common to all workpiece coordinate systems. In
general, the offset varies depending on the workpiece coordinate systems.
The value can be set from the PMC using the external data input function.
