Positioning data setting examples
The following table shows setting examples when "2-axis circular interpolation
control with center point designation (INC right arc, INC left arc)" 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 Command speed" so that the speed of each axis does not
exceed the " Pr.7 Speed limit value". (The speed limit does not function for the
speed calculated by the AD75 during interpolation control.)
Set "Positioning complete" assuming the next positioning
–
data will not be executed.
Set increment system, 2-axis circular interpolation control
– with center point designation. (Select clockwise or
counterclockwise according to the control.)
Designate the value set in " Pr.26 Acceleration time 1" as
–
the acceleration time at start.
Designate the value set in " Pr.9 Deceleration time 0" as
–
the deceleration time at deceleration.
Set the movement amount. (Assuming that the " Pr.1 Unit
setting" is set to "mm".)
Set the center 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.21 Interpolation
speed designation method".)
Set the time the machine dwells after the positioning stop
– (position command 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.
