(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)" 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.)

Refer to "List of Positioning Data ( Page 152, Section 5.3)" for information on the setting details.
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
Axis 3 (linear
interpolation axis)
Setting details
setting example
Set "Positioning complete" assuming
that the next positioning data will not be
executed.
Set incremental system, 3-axis helical
interpolation control with sub point
designation.
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
3000.0m
"mm" is set in "[Pr.1] Unit setting".)
Set the sub point 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
50
with the No. 1 positioning data.
Set the number of pitch for the linear
interpolation axis.
