9 MAIN POSITIONING CONTROL
Positioning data setting example
The following table shows setting examples when "2-axis fixed-dimension feed
control (fixed-dimension 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-
dimension
feed 2
– Set 2-axis fixed-dimension feed control.
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
– – Setting not required (setting value will be ignored).
Da.7
Command speed
6000.00
mm/min
–
Set the speed during movement. (Designate the composite
speed of reference axis 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
is 1 Positioning data N
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
The speed limit does not function for the speed calculated by the AD75 during interpolation control.
Because of this, observe the following precautions when setting the speed.
•
When the "composite speed" is set, set a value so the speed for each axis does not exceed the
" Pr.7 Speed limit value".
•
When the "reference axis speed" is set, 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.7
Speed limit value".
