Siemens Automation and Drives (A&D) is adding a Control Unit (CU) with Profinet interface to its modular series of Sinamics G120 frequency converters. This means the Sinamics G120 converter series can now also be used in complex automation architectures which require real-time Ethernet.
With the new control module, known as the Sinamics G120 CU 240S PN, Siemens is extending its Sinamics drive series to cover the power range 0.37-90kW and the voltage range 380-690 V. The Profinet link will therefore be available for complex systems, allowing integrated communication from the office to field level. In addition, the Sinamics G120 has the CU 240S DP and CU 240S control units as Profibus communication interfaces with Profidrive Profil 4.0 or with RS485.
The control units and the power modules of the Sinamics G120 converter series have been designed as separate, replaceable functional units and can be combined as required to create the desired converter. Engineering and commissioning are performed with the Sizer and Starter tools.
