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.)

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.
