Motor-integrated drive offers onboard safety features and communications
Siemens introduces the Sinamics G110M, a motor-integrated drive for Simogear gear motors, offering flexible control, integrated safety, simple installation and a space-saving design. With a high degree of protection — up to IP66 — this new gear motor drive provides the perfect solution to most material handling-related challenges, including conveyors, warehousing, logistics, baggage and cargo handling, post and parcel shipping, plus numerous industrial applications in the automotive, appliance and test stand industries.
Simogear gear motors offer high torque density, low noise and high efficiency — and now with Sinamics G110M, it becomes easier for designers and system builders to integrate gear motors into a variety of control architectures. Plug connections for onboard I/O ensure fast installation, while optional power connectors deliver even more time savings. The system is delivered pre-configured and the drive offers simple yet comprehensive onboard diagnostic features. Options such as internal braking resistors and motor brakes — operational simultaneously — and integrated features such as “Quick Stop” and the limit switch function make this system ideal for conveyor applications.
For uses requiring safety technology, the Sinamics G110M offers integrated safety functions such as “Safe Torque Off” (STO), which can be activated via a fail-safe input or via Profisafe, without needing additional safety monitoring components.
Sinamics G110M features integral USS/Modbus RTU, Profibus and Profinet / EtherNet/IP communication profiles.

North American users can now make full use of the benefits of a modular product, built to NEC (NFPA 70) standards, to configure common DC bus lineups and high horsepower drives, with optional UL/cUL listing
Siemens announces a new version of its popular Sinamics S120 Cabinet Module (CM) drive packages, compliant with North American standards and offered with optional UL/cUL listing. This unique product enables easy configuration of complex common DC bus lineups for multi-motor coordinated drive systems, as well as high horsepower (hp) stand-alone drives for a wide variety of industrial applications.
Key to the global growth of the Sinamics S120 CM range is its modularity and flexibility. Pre-designed, fully type-tested modules, including line side components, line infeeds (bus supplies) and motor inverters, all with a broad range of standard options, are selected and configured by the customer. Compared to the traditional approach of custom-engineered systems, this approach offers significant reduction in engineering and manufacturing lead times, which translates into reduced project costs and a compressed delivery schedule, while minimizing technical and commercial risk on even the most complex drive systems.
Individual cabinet modules from Siemens have a standardized power and control interface, which allows them to be freely positioned in a lineup that best suits the particular application and makes them easy to install and connect. The broad range of standard options including the DC bus current rating and enclosure type, for example, is available to tailor selections to best meet jobsite and environmental conditions. 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.
Sinamics S120 Cabinet Modules were designed to address the need for a complete, ready-to-connect-and-run drive system that enables customers to configure an enclosed drive lineup with a central line infeed (rectifier) and common DC bus, supplying power to multiple motor modules (inverters). Typical uses for such systems requiring multi-motor coordinated drive systems include paper machines, steel rolling mills, test stands, cranes, mixers and oil/gas field equipment. Very high horsepower single drive applications also benefit from this Siemens system.
The use of a common DC bus configuration with these new drive packages allows energy exchange between motors that are simply powering and others regenerating power back to the AC system, which can save up to 80% of the energy consumed when using standard installations.

Siemens Industry, Inc. announces reduced lead times for its Generation II Simotics 1FK7 servomotors. Highly-configurable to suit a wide variety of applications, this new line features seven shaft heights, Quick-Connect power connector and high-accuracy 20- and 24-bit field replaceable encoders in 10 styles, all combined with a four-week lead time beginning July 1, 2013 — and ultimately reduced to three-weeks beginning January 1, 2014 on all models.
The Generation II servomotor offers three inertia versions — standard, high-dynamic for rapid acceleration jobs, and high-inertia for maximum smooth running. These motors are designed for operation without external cooling and the heat is dissipated through the motor surface. With 10 styles of field-replaceable encoders, the 1FK7 Generation II servomotors provide easy maintenance in the field, with reduced downtime and operating cost savings. Further, a 10 percent improvement in continuous (S-1) power is achieved since the encoders are mechanically and thermally decoupled from the motor. The mechanical decoupling also means the encoder is more resistant to vibration conditions on the machine. In addition, there is no need for battery back-up on the absolute encoders.
Generation II Simotics 1FK7 servomotors provide users with 3x overload, 2.5 percent torque ripple, cross profiling for easier mounting, Siemens Drive-Cliq interface for easier field commissioning and unit recognition with the Siemens Sinamics S120 drive family, plain shaft or keyway design, three IP ratings and are supplied with or without holding brake.
The full application of engineering assistance and service of the global Siemens network supports this new line of servomotors.
