Chapter 9 Major Positioning Control
Positioning data setting example
[When "2-axis circular interpolation control with sub point designation (ABS circular
sub)" 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

–
Positioning
complete
–
Set "Positioning complete" assuming the next
positioning data will not be executed.
[Da.2]
Control system
ABS circular
sub
–
ABS circular
sub
–
Set absolute system, 2-axis circular
interpolation control with sub point designation.
[Da.3]
Acceleration time No. 1 – 1 –
Designate the value set in "[Pr.25]
Acceleration time 1" as the acceleration time
at start.
[Da.4]
Deceleration time No. 0 – 0 –
Designate the value set in "[Pr.10]
Deceleration time 0" as the deceleration time
at deceleration.
[Da.5]
Axis to be interpolated
QD77MS2 QD77MS4
Axis 2 –
Set the axis to be interpolated (partner axis).
If the self-axis is set, an error will occur.
[Da.6]
Positioning address/
movement amount
8000.0 m 6000.0 m 8000.0 m 6000.0 m
Set the positioning address. (Assuming "mm"
is set in "[Pr.1] Unit setting".)
[Da.7]
Arc address 4000.0 m 3000.0 m 4000.0 m 3000.0 m
Set the sub point address. (Assuming that the
"[Pr.1] Unit setting" is set to "mm".)
[Da.8]
Command speed
6000.00
mm/min
–
6000.00
mm/min
–
Set the speed when moving to the end point
address. (Designate the composite speed in
"[Pr.20] Interpolation speed designation
method".)
[Da.9]
Dwell time /JUMP
destination positioning
data No.
500ms – 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 to LEND
repetitions
10 – 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
QD77MS16
Axis 2 –
Set the axis to be interpolated.
If the self-axis is set, an error will occur.
[Da.21]
Axis to be interpolated
No.2
QD77MS16
– –
Setting not required (setting value is ignored).
[Da.22]
Axis to be interpolated
No.3
QD77MS16
– –
(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
POINT
Set a value in "[Da.8] Command speed" so that the speed of each axis does not
exceed the "[Pr.8] Speed limit value". (The speed limit does not function for the
speed calculated by the Simple Motion module during interpolation control.)
