An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning control.
 If the movement amount of each axis exceeds "1073741824 (=2
Composite speed" is set in "[Pr.20] Interpolation speed designation method"
The error "Outside linear movement amount range" (error code: 504) occurs at a
positioning start.
(The maximum movement amount that can be set in "[Da.6] Positioning


When the "reference axis speed" is set during 2-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 "[Pr.8] Speed
limit value".

Setting details
Set "Positioning complete" assuming the next
positioning data will not be executed.
Set absolute system 2-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.
Set the end point address. (Assuming "mm" is set in
"[Pr.1] Unit setting".)
Setting not required (setting value is ignored).
Set the speed during movement to the end point
address.
Set the time the machine dwells after the positioning
stop (command 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.
Set the axis to be interpolated.
If the self-axis is set, an error will occur.
Setting not required (setting value is ignored).
