6.1 REFERENCE POSITION RETURN
The reference position is a fixed position on a machine tool to which
the tool can easily be moved by the reference position return function.
For example, the reference position is used as a position at which tools
are automatically changed. Up to four reference positions can be
specified by setting coordinates in the machine coordinate system in
parameters (No. 1240 to 1243).
