(3) Positioning data setting example (Reference axis and interpolation axis are
designated as axis 1 and axis 2, respectively.)
The following table shows setting examples when "2-axis fixed-feed control (fixed-feed 2)" is set in positioning
data No. 4 of axis 1. (The required values are also set in positioning data No. 1 of axis 2.)
Refer to
Page 152, Section 5.3 for information on the setting details.

Setting details
Positioning data
No.1
[Da.1]
Operation pattern
Positioning
complete
Set "Positioning complete" assuming that the next
positioning data will not be executed.
[Da.2]
Control system
Fixed-feed 2
Set 2-axis fixed-feed 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.
[Da.5]
Axis to be interpolated
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
Set the movement amount. (Assuming "mm" is set in
"[Pr.1] Unit setting".)
[Da.7]
Arc address
Setting not required. (Setting value will be ignored.)
[Da.8]
Command speed
6000.00mm/min
Set the speed during movement. (Designate the
composite speed of reference axis speed in "[Pr.20]
Interpolation speed designation method".)
[Da.9]
Dwell time
500ms
Positioning stops. Set the time the machine dwells after
the positioning stop (pulse output stop) to the output of
the positioning complete signal.
[Da.10]
M code
10
Set this when other sub operation commands are
issued in combination with the No. 1 positioning data.
