Compensation data, which is set using 128–point straightness
compensation data, is divided into parts in each compensation point
interval and output.
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.

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.
