In the ZX plane coordinate system at the origin of which the reference
point of tool post 1 is set, set the X coordinate (ε) of the reference point
of tool post 2 in parameter No. 8151, and its Z coordinate (ζ) in parameter
No.8152 .
The unit of setting is the least command increment. For an axis subject
to diameter specification, a diameter value is to be specified.
Measure (ε) and(ζ) when reference point return operation is completed
with the four axes (X1, Z1, X2, Z2). When the relative coordinate
parameters (Nos.8151 and 8152) of the two tool posts are to be updated,
reference point return operation must always be completed with the four
axes beforehand. Otherwise, the internally memorized relational
positions of the tool posts are not updated to new parameter values.
