Introduction

Presentation

This guide contains information on installation and describes the PROFIBUS DP services available. The "communication variables" guide describes the operating modes, as well as the Altivar 312 variables and parameters which can be accessed via the communication bus.

The PROFIBUS DP communication card (catalog number VW3 A312 07) is used to connect an Altivar 312 drive to a PROFIBUS DP bus.

Data is exchanged in order to make use of all the Altivar 312 functions:

•Configuring functions

•Uploading adjustment parameters

•Control-signaling

•Monitoring

•Diagnostics

The PROFIBUS DP card has an open style connector.

The cable for connection to the PROFIBUS DP bus must be ordered separately.
