9 MAJOR POSITIONING CONTROL
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
center 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.)

- -
Set "Positioning complete" assuming that
the next positioning data will not be
executed.
Da.2 Control

ABS helical
right
ABS helical left
- -
Set absolute system, 3-axis helical
interpolation control with center point
designation. (Select clockwise or
counterclockwise according to the control.)
Da.3 Acceleration
time No.
1 - -
Specify the value set in
" Pr.25 Acceleration time 1" as the
acceleration time at start.
Da.4 Deceleration
time No.
0 - -
Specify the value set in
" Pr.10 Deceleration time 0" as the
deceleration time at deceleration.
Da.5 Axis to be
interpolated
Axis 2 - -
Set the axis to be interpolated (partner axis).
If the self-axis is set, an error will occur.

Set the speed during movement to the end
point address. (Set the composite speed in
" Pr.20 Interpolation speed designation

Da.9 Dwell time
500ms - -
Set the time the machine dwells from the
positioning stop (pulse output stop) to the
output of the positioning complete signal.
Da.10 M code
10 - 50
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.
Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
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 QD75N during interpolation control.)
