7.4.3 Work Coordinate System
It is the 32 kinds of coordinate systems defined by the offset of each axis against the base
coordinate system.
Work Coordinate System No. 0 is reserved as Base Coordinate System (= Work Coordinate
System Offset = 0) by the system.
Set the offset of each axis as described below.
The direction of the coordinate system rotation (positive direction of R offset) is defined as
described below by the axis structure of the coordinate system definition unit.
