As pitch error data, always set incremental values as viewed in the
negative direction (direction toward the left in Fig. 1.3.9 (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.

Setting Description
5426#5 1 Bidirectional pitch error compensation, 1: Enabled/0:
Disabled
5420 23 Number of the pitch error compensation point for the
reference position
5421 20 Number of the most distant pitch error compensation
point on the - side for travel in the positive direction
5422 27 Number of the most distant pitch error compensation
point on the + side for travel in the positive direction
5423 1 Pitch error compensation magnification
5424 10000 Pitch error compensation point interval
5425 - For a rotation axis, amount of travel per rotation in pitch
error compensation
5427 30 Number of the most distant pitch error compensation
point on the - side for travel in the negative direction
5428 -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. 5428, 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.
