Positioning data setting example
[Reference axis is designated as axis 1.]
The following table shows setting examples when "4-axis linear interpolation
control (ABS linear 4)" is set in positioning data No. 1 of axis 1. (The required
values are also set in positioning data No. 1 of axis 2, axis 3 and axis 4.)

POINTS
(1) When the "reference axis speed" is set during 4-axis linear interpolation 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 "
Speed limit value".
(2) Refer to Section 9.1.6 "Interpolation control" for the reference axis and
interpolation axis combinations.

Axis 4
Setting details
Set "Positioning complete"
– assuming the next positioning
data will not be executed.
Set absolute system 4-axis
–
linear interpolation control.
Designate the value set in
" Pr.25
–
Acceleration time 1"
as the acceleration time at start.
Designate the value set in
" Pr.10
Deceleration time 0"
–
as the deceleration time at
deceleration.
Setting not required (setting
value will be ignored).
–
When axis 1 is used as a
reference axis, the interpolation
axes are axes 2, 3 and 4.
Set the end point address.
(Assuming "mm" is set in
" Pr.1 Unit setting".)
Setting not required (setting
–
value will be ignored).
Set the speed during movement
–
to the end point address.
Set the time the machine dwells
after the positioning stop (pulse
–
output stop) to the output of the
positioning complete signal.
Set this when other sub
operation commands are issued
–
in combination with the No. 1
positioning data.
