Overview

2.1

General information

In this chapter you will first get an overview of the mechanical design, the installation or assembly of the linear

units as well as a description of the mode of operation. Then the various linear units are explained in detail.
The instructions for commissioning / parameterization and user programming of the axis system depend on the

motors used, the corresponding controllers with output stages and their documentation.

General structure of the linear units of the LES series

The structure of the linear units is shown in the following pictures, drawings and parts lists.

2.2

Functionality of the linear unit

The linear units of the LES series (spindle drive) are of modular design.
These linear units are based on linear guide rails (LFS) with the corresponding shaft slides (WS), a ball screw drive

and the optional motor drive module. The linear guide rails consist of rigid aluminium profiles with precision steel

shafts. The shaft slides are based on the rolling of steel balls on steel inserts guided in aluminium profiles and the
