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.)

Chapter 9 Major Positioning Control
Setting details
Set "Positioning complete" assuming the next
positioning data will not be executed.
Set absolute system, 2-axis circular
interpolation control with sub point designation.
Designate the value set in "[Pr.25]
Acceleration time 1" as the acceleration time
at start.
Designate the value set in "[Pr.10]
Deceleration time 0" as the deceleration time
at deceleration.
Set the positioning address. (Assuming "mm"
is set in "[Pr.1] Unit setting".)
Set the sub point address. (Assuming that the
"[Pr.1] Unit setting" is set to "mm".)
Set the speed when moving to the end point
address. (Designate the composite speed in
"[Pr.20] Interpolation speed designation
method".)
Set the time the machine dwells after the
positioning stop (command stop) to the output
of the positioning complete signal.
Set this when other sub operation commands
are issued in combination with the No. 1
positioning data.
Set the axis to be interpolated.
If the self-axis is set, an error will occur.
Setting not required (setting value is ignored).
