The TNC provides the functions described below:
 Coordinate system range:
Here you specify the coordinate system on which the data entered
in the Limit values range is to be based.
 Machine system :
Limit values are based on the machine coordinate system (M91
system).
 Workpiece system :
Limit values are based on the workpiece coordinate system. The
workpiece coordinate system is based on the datum set on the
workpiece without consideration of a defined basic rotation and
without consideration of any active coordinate transformations.
 Input system :
Limit values are based on the input coordinate system. The input
coordinate system coincides with the workpiece coordinate
system if no coordinate transformations are active. If coordinate
transformations are active (basic rotation, datum shift, mirroring,
rotation, scaling factor, tilted working plane), the input coordinate
system differs from the workpiece coordinate system
accordingly.
