ϕ : Number of the straightness compensation point at extremely negative point of the
moving axis (parameter No.13381 - 13386)
π : Number of the straightness compensation point at extremely positive point of the
moving axis
δ : Number of the straightness compensation point for the reference point of the moving
axis
The following relationships hold :
1. δ = ϕ + ( γ - α )
2. π = ϕ + ( β - α )
and π, δ are automatically calculated from α, β, γ and ϕ.
Therefore, no parameters need to be set for them.
- Display and setting of straightness compensation data
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.
- Input by MDI
- Input by G10
- Input and output by input/output device interface
- 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.
