SINAMICS G: Speed control of a G110M/G120/G120C/G120D/G120P using S7-300/400 (STEP 7 V5) with PROFINET/PROFIBUS, Safety Integrated and HMI
A SIMATIC S7-300/400 is to control a SINAMICS G110M/G120 drive via PROFINET or PROFIBUS DP.
The controller is to have both read and write access to process data of the inverter (control word and setpoint or status word and actual value) and to inverter parameters (ramp-up and ramp-down time, error memory).
In this context, the current faults and alarms of the inverter are to be displayed with the error number and as plain text on an operator panel. The current and acknowledged messages in the fault buffer of the inverter are to be visualized as well.
For the SINAMICS types G110M, G120, G120C, G120D and G120P, the above task was implemented with a CPU 315-2 DP/PN. The blocks created for this purpose, one for process data communication and one for parameter access, can be used as a basis for your own applications.
The documentation for the application example describes the necessary configuration and programming of the required functions.
The projects in this example were created with the following versions:
- STEP 7 V5.5 + SP4
- WinCC flexible 2008 + SP3
- SINAMICS G with firmware V4.6 or V4.7
- STARTER V4.4
The downloads of the STEP 7 projects only differ in the fieldbuses used, the SINAMICS G types used and in its firmware versions.
