128 straightness compensation points
- Specification
In straightness compensation, compensation data is set as the compensation amounts at the
individual compensation points, in the same way as in stored pitch error compensation. This
enables fine compensation.
Up to six combinations of moving axes and compensation axes can be used in the
straightness compensation function.
- Up to 128 compensation points can be set per axis.
- The settings ( a, b, , , y and z ) at the individual compensation points can be from –128 to
+127.
- The method of setting data and the compensation timing are the same as those of pitch
error compensation.
- To use this function, the pitch error compensation points of a moving axis should be
within 128 points.
- The number of straightness compensation points is the same as that of stored pitch error
compensation points of a moving axis.
- Relationship between pitch error compensation points
and straightness compensation points on a moving axis
The relationship between pitch error compensation points and straightness compensation
points on a moving axis is as follows.
Stored pitch error compensation points on a moving axis.
Straightness compensation points on a moving axis
α : Number of the pitch error compensation point at extremely negative point of the moving
axis (parameter No.3621)
β : Number of the pitch error compensation point at extremely positive point of the moving
axis (parameter No.3622)
γ : Number of the pitch error compensation point for the reference point of the moving axis
(parameter No.3620)
