This application only applies to SINAMICS G120 CU´s with Firmware < V4.0



The SINAMICS G120 is to be controlled from an S7-300 CPU via PROFIBUS.

The integrated safety functions of the SINAMICS G120 are to be controlled via the fail-safe digital inputs of the SINAMICS G120.



In this function example, the control of a SINAMICS G120 (control word and frequency setpoint) will be demonstrated using an S7-300 CPU and a specific program example.

This program example comprises an S7 program to control the SINAMICS G120 and the appropriate configuration in the SINAMICS G120.
