The 128–point straightness compensation data is set by the stored pitch
error compensation data setting screen. On this setting screen, set
128–point straightness compensation data above compensation point
number 6000.
These data can be input and output by the following methods.
D Input by MDI
D Input by G10
D Input and output by input/output device interface
D Input by PMC window (function code 18)
(It is not possible to input and output by the method other than the above
methods.)
The 128–point straightness compensation data is input and output in
parameter format, in the same way as stored pitch error compensation
data. A straightness compensation point number plus 20000 is equal to
the corresponding parameter number. (The format is the same as that of
pitch error compensation data.)
The input/output of 128–point straightness compensation data is
performed at the same time as stored pitch error compensation data.
When 128–point straightness compensation data is used, the point
number plus 20000 is equal to the corresponding parameter number as for
the stored pitch error compensation.
As for the method of setting parameters for the moving axes, the
compensation axes and the effective magnification, the followings can be
set.
(1)A single compensation axis can be set for a single moving axis.

When the parameters are set as shown above, by moving the machine
along the 1
st
axis, compensation is applied to the 2
nd
axis. Similarly, by
moving the machine along the 3
rd
and 5
th
axis, compensation is applied
to the 4
th
and 6
th
axis, respectively.
The number of parameter for the magnification that is effective for the
individual moving and compensation axis combination is as given in the
table above.
