9 MAJOR POSITIONING CONTROL
Positioning data setting example
[Reference axis and interpolation axis are designated as axis 1 and axis 2,
respectively.]
The following table shows setting examples when "2-axis fixed-dimension feed
control (fixed-feed 2)" 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 Fixed-feed 2 – Set 2-axis fixed-feed 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
µ
m 6000.0
µ
m
Set the positioning address. (Assuming "mm" is set in
" Pr.1 Unit setting".)
Da.7 Arc address – – Setting not required (setting value will be ignored).
Da.8 Command speed
6000.00
mm/min
–
Set the speed during movement. (Designate the composite
speed of reference axis 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.
A
x
is 1 Positioning data N
o
. 1
Da.10 M 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
•
When the "reference axis speed" is set during 2-axis fixed-feed control, set so the major axis side
becomes the reference axis. If the minor axis side is set as the reference axis, the major axis side
speed may exceed the " Pr.8 Speed limit value".
