9 MAIN POSITIONING CONTROL
Positioning data setting example
The following table shows setting examples when "2-axis circular interpolation
control with auxiliary point designation (ABS circular interpolation)" is set in
positioning data No. 1 of axis 1. (The required values are also set in positioning
data 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 method
ABS circular
interpolation
–
Set absolute system, 2-axis circular interpolation control with
auxiliary point designation.
Da.3
Acceleration time
No.
1 –
Designate the value set in "
Pr.26 Acceleration time 1" as
the acceleration time at start.
Da.4
Deceleration time
No.
0 –
Designate the value set in " Pr.9 Deceleration time 0" as
the deceleration time at deceleration.
Da.5
Positioning address/
movement amount
80000.0
µ
m
60000.0
µ
m
Set the positioning address. (Assuming "mm" is set in
"
Pr.1 Unit setting".)
Da.6
Arc address
40000.0
µ
m
30000.0
µ
m
Set the auxiliary point address. (Assuming that the " Pr.1
Unit setting" is set to "mm".)
Da.7
Command speed
6000.00
mm/min
–
Set the speed when moving to the end point address.
(Designate the composite speed in "
Pr.21 Interpolation
speed designation method".)
Da.8
Dwell time
500ms –
Set the time the machine dwells after the positioning stop
(position command output stop) to the output of the
positioning complete signal.
Ax

o
. 1
Da.9
M code
10 –
Set this when other auxiliary 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.7 Command speed" so that the speed of each axis does not
exceed the " Pr.7 Speed limit value". (The speed limit does not function for the
speed calculated by the AD75 during interpolation control.)
