(c) 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 circular interpolation control with center point
designation (INC circular right, INC circular left)" is set in positioning data No. 1 of axis 1. (The required values
are also set in positioning data No. 1 of axis 2.)

Set a value in "[Da.8] Command speed" so that the speed of each axis does not exceed the "[Pr.8] Speed limit value". (The
speed limit does not function for the speed calculated by the LD75 during interpolation control.)

CHAPTER 9 MAJOR POSITIONING CONTROL
Setting details
Set "Positioning complete" assuming that the next
positioning data will not be executed.
Set incremental system, 2-axis circular interpolation
control with center point designation. (Select clockwise
or counterclockwise according to the control.)
Designate the value set in "[Pr.25] Acceleration time 1"
as the acceleration time at start.
Designate the value set in "[Pr.10] Deceleration time 0"
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 movement amount. (Assuming "mm" is set in
"[Pr.1] Unit setting".)
Set the arc address. (Assuming "mm" is set in "[Pr.1]
Unit setting".)
Set the speed during movement. (Designate the
composite speed in "[Pr.20] Interpolation 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.
