Preliminary information

This guide is designed to provide the most complete information the operator needs to correctly and
safely install and operate the following encoders

fitted with Profibus interface

:

XAC8018/1PB-xx

(18 bit singleturn encoder)

XAC8013/16384PB-xx

(13 +14 bit multiturn encoder)

XAC8016/16384PB-xx

(16 +14 bit multiturn encoder)

For technical specifications please refer to the product datasheet.

To make it easier to read the text, this guide can be divided into some main sections.

In the first section (from chapter 1 to chapter 4) general information concerning the safety, the
mechanical installation and the electrical connection.

In the second section (chapter 5) information on how to install and configure the encoder under the
Siemens STEP7 development environment as well as tips for setting up and running properly and
efficiently the unit are provided.

In the third section (chapters 6 and 7) both general and specific information is given on the Profibus
interface. In this section the interface features and the parameters implemented in the unit are fully
described.
