In stored pitch error compensation, the pitch error compensation pulse at each pitch error
compensation point is output in the interval between that point and the next compensation
point, as shown in the figure below.
Fig.1.1 Stored Pitch Error Compensation
In interpolation type pitch error compensation, the compensation amount at each error
compensation point is divided into pulses in the interval between that point and the next
point on the travel axis and output, as shown in the figure below.
