Interpolation of Two Axes
This section gives examples of linear interpolation and circular interpolation for a machine with
two orthogonal axes that are mounted on ball screws directly driven by Servomotors. The
machine is programmed with a motion program. Control with a ladder program that uses
motion commands is also possible, but it requires complex programming. An example of a
motion program is provided in this manual.

8.2.1
Machine Configuration
The machine configuration that is used in this example consists of an X-Y plotter that has two
orthogonal axes as shown below.
The ball screw lead (i.e., the travel distance for one rotation) is 6 mm for each axis.
8-6
This section describes the basic programming necessary to move the machine. The example in
this section does not include interlocks or other elements that must be included for an actual sys-
tem.
