9 MAJOR POSITIONING CONTROL
Positioning data setting examples
[Reference axis and interpolation axis are designated as axis 1 an d axis 2,
respectively.]
The following table shows setting examples when "2-axis circular interpolation
control with center point designation (INC circular right, INC circular lef t)" is set inpositioning data No. 1 of axis 1. (The required values are also set in positioningdata No. 1 of axis 2.)

Setting details
Da.1 Operation pattern Positioning
complete Set "Positioning complete" assuming the next positioning
data will not be executed.
Da.2 Control system
INC circular
right
INC circular
left
Set incremental system, 2-axis circular interpolation control
with center point designation. (Select clockwise or
counterclockwise according to the control.)
Da.3 Acceleration time
No. 1–
Designate the value set in " Pr.25 Acceleration time 1" as
the acceleration time at start.
Da.4 Deceleration time
No. 0–
Designate the value set in " Pr.10 Deceleration time 0" as
the deceleration time at deceleration.
Da.5 Axis to be
interpolated 1–
Set the axis to be interpolated (partner axis).
If the self-axis is set, an error will occur.
Da.6 Positioning address/
movement amount 8000.0 µm 6000.0 µmSet the movement amount. (Assuming that the " Pr.1 Unit
setting" is set to "mm".)
Da.7 Arc address 4000.0 µm 3000.0 µmSet the center point address. (Assuming that the " Pr.1
Unit setting" is set to "mm".)
Da.8 Command speed 6000.00
mm/min
Set the speed when moving to the end point address.
(Designate the composite speed in " Pr.20 Interpolation
speed designation method".)
Da.9 Dwell time 500ms Set the time the machine dwells after the positioning stop
(pulse output stop) to the output of the positioning complete
signal.
Axis 1 Positioning data No. 1
Da.10M code 10 Set this when other sub operation commands are issued in
combination with the No. 1 positioning data.
Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
Set a value in " Da.8 Comm and 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 QD75 during interpo lation control.)
