System Parameters
Workpiece Origin Offset
Values
The setting range will vary with the minimum setting unit and pulse rate in the
machine parameters.
Mechanical origin
This parameter is set when you want to move the origin after the mechanical
origin has been found.
The workpiece origin offset is an offset from the reference origin. The work-
piece origin offset values are referenced when G51 (SELECT WORKPIECE
COORDINATE SYSTEM) is executed in the G-language program.

Reference origin
This can be useful, for example, in carrying out operations such as drilling
holes in the positions shown above.
Move the workpiece origin to the workpiece origin position by changing the
workpiece origin offset value. Carry out the positioning for drilling the holes by
selecting the workpiece coordinate system.
The origin can be changed temporarily using G53 (change workpiece origin
offset) in the G language program.
