(c) Positioning data setting example
• Reference axis, circular interpolation axis, and linear interpolation axis are specified as axis 1, axis 2, and
axis 3, respectively.
The following table shows setting examples when "helical interpolation control with sub point designation (INC
helical right, INC helical 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 and axis 3.)

Setting details
Set "Positioning complete" assuming
that the next positioning data will not be
executed.
Set incremental system, 3-axis helical
interpolation control with center point
designation. (Select clockwise or
counterclockwise according to the
control.)
Specify the value set in "[Pr.25]
Acceleration time 1" as the acceleration
time at start.
Specify 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. (Set
the composite speed in "[Pr.20]
Interpolation speed designation
method".)
Set the time the machine dwells from
the positioning stop (pulse output stop)
to the output of the positioning complete
signal.
Set this item when other sub operation
commands are issued in combination
with the No. 1 positioning data.
Set the number of pitch for the linear
interpolation axis.
