The following table shows setting examples when "4-axis fixed-feed control (fixed-feed 4)" is set in positioning
data No. 4 of axis 1. (The required values are also set in positioning data No. 1 of axis 2, axis 3 and axis 4.)
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 4
Set 4-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
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.
[Da.6]
Positioning
address/movement
amount
4000.0
m
8000.0
m
4000.0
m
3000.0
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
6000.00
mm/min
Set the speed during movement.
[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.
