2.1 Compensation methods
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 travel axis, as shown in the figure below.
Fig. 2.1(a) 128-Point Straightness Compensation Method
With the interpolated 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 travel axis, and output to the compensation axis.
