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.)

•
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 "
value".
Set "Positioning complete" assuming the next positioning
–
data will not be executed.
– Set 2-axis fixed-feed control.
Designate the value set in " Pr.25
–
as the acceleration time at start.
Designate the value set in " Pr.10
–
as the deceleration time at deceleration.
Set the axis to be interpolated (partner axis).
–
If the self-axis is set, an error will occur.
Set the positioning address. (Assuming "mm" is set in
" Pr.1
Unit setting".)
– Setting not required (setting value will be ignored).
Set the speed during movement. (Designate the composite
speed of reference axis speed in " Pr.20
–
speed designation method".)
Set the time the machine dwells after the positioning stop
– (pulse output stop) to the output of the positioning complete
signal.
Set this when other sub operation commands are issued in
–
combination with the No. 1 positioning data.
