[Setting examples when the reference axis and interpolation axis ar e designated
as axes 1 and 2, respectively.]
The following table shows the setting examples when "2-axis speed contr ol
(forward run: speed 2)" is set in the positioning data No. 1 of axis 1 (reference
axis).

Setting details
Da.1 Operation pattern Positioning
complete –Setting other than "Positioning complete" is not possible in
speed control.
Da.2 Control system Forward run
speed 2 – Set 2-axis speed 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 1–Set the axis to be interpolated (partner axis).
If the self-axis is set, an error will occur.
Da.6 Positioning address/
movement amount – – Setting not required (setting value will be ignored).
Da.7 Arc address – – Setting not required (setting value will be ignored).
Da.8 Command speed 6000.00
mm/min 3000.00
mm/min Set the speed to be commanded.
Da.9 Dwell time – – Setting not required (setting value will be ignored).
Axis 1 Positioning data No. 1
Da.10M code 10 –
Set this when other sub operation commands are issued in
combination with the No. 1 positioning data. (" Pr.18 M
code ON signal output timing" setting only possible in the
WITH mode.)
