XY-Table

XY tables are used in a variety of applications with different positioning requirements. Usually horizontal motion involves 2 (or more) axes of servo performing linear or circular interpolation.

XY tables utilize servo motor technology for accurate positioning. As shown illustrated on the first page, two servo motors are connected to a table to move the application in X and Y direction.

The 2 Motors are controlled by a MR-J4W2-B servo amplifier, which is the latest technology from Mitsubishi Electric. The movement and interpolation is calculated with the simple motion controller LD77MS.

In combination with a L Series PLC and its built in features, a complete solution can be offered with less components. Thanks to the SSCNET III/H Network, all internal servo parameters can be set directly from the PLC.

In general, XY tables do not require a lot of maintenance, and are considered to be highly accurate, easy-to-use. However, mechanical parts can still be a problem after time. Depending on the weight of the load, ball screws within XY tables and other mechanical components can acquire a significant amount of wear and may need to be renewed regularly. Therefore, Mitsubishi Electric developed new functions to estimate frictions & vibrations which support preventative maintenance of machine components. These functions are integrated in the new MR-J4 series.
