[Data type] 2-word axis
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Metric machine 0.01 0.001 0.0001 mm
Inch machine 0.001 0.0001 0.00001 inch
Rotary axis 0.01 0.001 0.0001 deg

This parameter specifies the coordinates of the reference position of
an axis on the coordinate system of another axis under composite
control.
The parameter is validated when bit 4 (MPMx) of parameter No. 8162
is set to 1.
[Example] Exercising composite control to replace the X1-axis with the X2-axis

) are the coordinates of the reference position of tool post
2 on the workpiece coordinate system of tool post 1. (∆X
2m
, ∆Z
2m
) are
the coordinates of the reference position of tool post 1 on the
workpiece coordinate system of tool post 2.
∆X
