Interpolation type straightness compensation
- Specification
Compensation data, which is set using 128-point straightness compensation data, is divided
into parts in each compensation point interval and output.
- Compensation method
With the 128-point straightness compensation method, the straightness compensation
amount at each compensation point is output to the compensation axis, in the interval
between that point and the next point on the moving axis, as shown in the figure below.
Fig. 1 128-point straightness compensation method
With the interpolation type straightness compensation method, the straightness
compensation amount at each compensation point is divided into pulses in the interval
between that point and the next point on the moving axis, and output to the compensation
axis.
