Positioning data setting example
The following table shows setting examples when "2-axis circular interpolation
control with auxiliary point designation (INC circular interpolation)" is set in
positioning data No. 1 of axis 1. (The required values are also set in positioning
data No. 1 of axis 2.)

POINT
Set a value in " Da.7
exceed the " Pr.7
Speed limit value". (The speed limit does not function for the
speed calculated by the D75P2 during interpolation control.)
Set "Positioning complete" assuming the next positioning
–
data will not be executed.
Set increment system, 2-axis circular interpolation control
–
with auxiliary point designation.
Designate the value set in " Pr.26 Acceleration time 1" as
–
the acceleration time at start.
Designate the value set in " Pr.9
–
the deceleration time at deceleration.
Set the movement amount. (Assuming that the " Pr.1
setting" is set to "mm".)
Set the auxiliary point address. (Assuming that the " Pr.1
Unit setting" is set to "mm".)
Set the speed during movement. (Designate the composite
–
speed in " Pr.21 Interpolation speed designation method".)
Set the time the machine dwells after the positioning stop
–
(pulse output stop) to the output of the positioning complete
signal.
Set this when other auxiliary operation commands are
–
issued in combination with the No. 1 positioning data.
