Siemens' Sinamics S120 Cabinet Module drive packages are compliant with North American standards

Siemens announces a new version of its Sinamics S120 Cabinet Module (CM) drive packages, compliant with North American standards and offered with optional UL/cUL listing. The Sinamics S120 CM range is built for modularity and flexibility. Pre-designed, fully type-tested modules, including line side components, line infeeds (bus supplies) and motor inverters, all with a range of standard options, are selected and configured by the customer.

Individual cabinet modules from Siemens have a standardized power and control interface. Despite standardization, this design offers a high degree of flexibility for both power and control circuits. For line side converters, there is a choice of non-regenerative Basic Line Module (diode rectifier) or fully regenerative Smart and Active Line Modules. Both of these are IGBT inverters, the Smart Line Module being a more basic six-pulse unit, while the Active Line Module offers low harmonics exceeding the demands of IEEE 519.  Unity or controllable power factor and DC bus voltage control allows stable operation of motors even on irregular power supply systems. Basic and Smart Line Modules can also be configured in 12-, 18- or 24-pulse systems for low harmonic operation. All these configurations are now compliant with the National Electrical Code (NFPA 70) and Short Circuit Current Ratings per UL508A supplement SB, up to 100 kA.

The SINAMICS S120 firmware, combined with Drive-CLiQ (the flexible backplane bus), allows users to assign control units multiple Line and Motor Modules, plus mount the control units and associated I/O and sensor modules anywhere within the line-up or even remotely in a centralized control cabinet or control room. Drive-CLiQ provides automatic electronic nameplate, real-time control data transfer, diagnostic and parameter value gathering and fault tolerant transfer protocols. For external control systems, high-speed industrial Ethernet communications can be parameterized for EtherNet/IP, PROFINET or Sinamics Link (peer-to-peer), while programming can be done via a dedicated port or Ethernet TCP on the Ethernet network simultaneously with Profinet or EtherNet /IP.
