15.9 BI-DIRECTIONAL PITCH ERROR COMPENSATION
In bi-directional pitch error compensation, different pitch error
compensation amounts can be set for travel in the positive direction and
that in the negative direction, so that pitch error compensation can be
performed differently in the two directions, in contrast to stored pitch
error compensation, which does not distinguish between the directions
of travel. In addition, when the direction of travel is reversed, the
compensation amount is automatically calculated from the pitch error
compensation data to perform compensation in the same way as in
backlash compensation. This reduces the difference between the paths
in the positive and negative directions.
