Chapter 9 Major Positioning Control
Restrictions
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 operation.

If the movement amount of each axis exceeds "1073741824 (=2
30
)" when "0:
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
address/movement amount" is "1073741824 (=2
30
)".)
Positioning data setting example
[When "2-axis linear interpolation control (INC linear 2)" is set in positioning data
No. 1 of axis 1]
• Reference axis ............. Axis 1
• Interpolation axis.......... Axis 2 (The required values are also set in positioning
data No. 1 of axis 2.)

[Da.1] Operation pattern
Positioning
complete
–
Set "Positioning complete" assuming the next
positioning data will not be executed.
[Da.2] Control method INC linear 2 –
Set incremental system 2-axis linear
interpolation 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.

Set the movement amount. (Assuming "mm" is
set in "[Pr.1] Unit setting".)
[Da.7] Arc address – – Setting not required (setting value is ignored).
[Da.8] Command speed

mm/min
– Set the speed during movement.
[Da.9]

destination positioning
data No.
500ms –
Set the time the machine dwells after the
positioning stop (command stop) to the output
of the positioning complete signal.
[Da.10]
M code/Condition data
No./Number of LOOP

10 –
Set this when other sub operation commands
are issued in combination with the No.1
positioning data.
[Da.20]
Axis to be interpolated
No.1
Axis 2 –
Set the axis to be interpolated.
If the self-axis is set, an error will occur.

Setting not required (setting value is ignored).
[Da.22]
Axis to be interpolated
