As pitch error data, always set incremental values as viewed in the
negative direction (direction toward the left in Fig. 1.3.8 (b)).

Set negative-direction pitch error data for all the points for which
positive-direction pitch error data has been set.
As negative-direction pitch error data, always set incremental values
as viewed in the negative direction.

Number of the most distant pitch error compensation
point on the - side for travel in the negative direction
3627 -2
Pitch error compensation amount (absolute value) at the
reference position when the machine moves to the
reference position in the direction opposite to that of the
reference position return
This example assumes that the direction of a manual reference
position return is positive. For parameter No. 3627, therefore, set -2,
which is the pitch error compensation amount (absolute value) at the
reference position when the machine moves to the reference position
in the negative direction.
