Configuring the inverter and integrating it in the Profibus network

In STEP 7, the inverter can be connected to an S7 control in two ways:

1. Using the inverter GSD

The GSD is a standardized description file for a PROFIBUS slave. It is used by all

controllers that are PROFIBUS masters.

2. Via the STEP 7 object manager

This somewhat more user-friendly method is only available for S7 controls and installed

Drive_ES_Basic.

The following section describes how to configure the inverter using the GSD.

Installing the GSD in STEP 7

The GSD of the SINAMICS inverters are available in the Internet.

It is integrated in STEP 7 via HW Config.
