SINAMICS G: Speed control of a G120 using S7-300/400 (STEP 7 V5) with PROFIBUS and Safety Integrated (encoderless,not via PROFIsafe)
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.
