Setting details 
Da.1 Operation pattern  Termination  –  – 
Set "Termination" assuming the next 
positioning data will not be executed. 
Da.2 Control method  Fixed-feed 3  –  –  Set 3-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 and 3. 
Da.6 
Positioning address/ 
movement amount 
10000.0 
µ
m 5000.0 
µ
m 6000.0 
µ
m 
Set the positioning address. (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  –  – 
Set the time the machine dwells after the 
positioning stop (pulse output stop) to the 
output of the positioning complete signal. 
Axis 1   Positioning data No. 1 
Da.10 
M code  10  –  – 
Set this when other sub operation commands 
are issued in combination with the No. 1 
positioning data. 
 
   Refer to section "5.3 List of positioning data" for information on the setting details.  
 
POINTS 
 
•
 When the "reference axis speed" is set during 3-axis fixed-feed 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". 
•
 Refer to section "9.1.6 Interpolation control" for the reference axis and 
interpolation axis combinations.
