9 MAJOR POSITIONING CONTROL
Positioning data setting example
[Reference axis and interpolation axis are designated as axis 1 and axis 2,
respectively.]
The following table shows setting examples when "2-axis fixed-dimension feed
control (fixed-feed 2)" is set in positioning data No. 1 of axis 1. (The required
values are also set in positioning data No. 1 of axis 2.)

POINTS
•
When the "reference axis speed" is set during 2-axis fixed-feed control, set so the
major axis side becomes the reference axis. If the minor axis side is set as the
reference axis, the major axis side speed may exceed the "
reference axis, the major axis side speed may exceed the "
Pr.8
Speed limit
value".
