When using bidirectional pitch error compensation, set the number of the
pitch error compensation position at the extremely negative position for
each axis in the case of negative–direction movement.
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.

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.
