SINAMICS G: Speed control of a G120 using S7-300/400 (TIA Portal) with PROFINET/PROFIBUS, Safety Integrated (via PROFIsafe) and HMI
A failsafe SIMATIC S7-300/400F PLC is to control a SINAMICS G120 drive via PROFINET or PROFIBUS-DP .
The PLC shall have reading and writing access to the drive's process data (control word and speed setpoint respectively status word and actual speed) and to the drive's parameters (ramp-up time and ramp-down time).
The Safety Functions of the drive shall be addressed from the failsafe PLC.
The current faults and alarms of the drive are to be displayed at a panel with their error numbers and as plaintext. Also the current and acknowledged messages in the drive's fault buffer shall be visualized.
The problem above is exemplarily implemented with a SINAMICS G120 Control Unit CU240x-2...-F (e. g. CU240E-2 DP-F or CU240E-2 PN-F) and a S7-300/400F CPU with PROFIBUS connection (e .g. CPU 315F-2 PN/DP). The necessary parameterization resp. the programming of the required functions is described in the documentation belonging to this application example.
