Lexium 32 servo drive range with servo motors

Schneider Electric's Lexium 32 servo drives reduce cabinet space, simplify interoperability, and improve machine performance.

Schneider Electric Lexium 32 servo drives with servo motors (right), provide machine builders exceptional performance, an unprecedented level of sophistication and outstanding power in a motion control solution, the company said. With three models to choose from, selection and use throughout a machine's lifecycle is easier. Costs are minimized by reducing cabinet space, time-to-market and interoperability into new or existing architectures.

"Machine builders in industries like printing, packaging, textiles and material handling need solutions that are productive, fast and easy to implement," says Jeff Jervah, business director for automation & drive solutions for Schneider Electric.


Lexium 32 servo drive features

Rapid mechanical and electrical installation and maintenance are more easily accomplished with Schneider Electric Lexium 32 servo drives, the company says. The designs:

- Wiring is simpler. All connections are at the front or the top, incorporating removable color-coded connectors, adding an on-board HMI, and using motors with straight, angled and rotatable connectors to accommodate any orientation.

- Three auto tuning wizards help users to customize the system based on their level of expertise (novice to advanced).

- The drives enhance Interoperability by incorporating support for a wide variety of standardized hardware and software motion interfaces, including CANopen/CANmotion, DeviceNet, Profibus DP and EtherNet/IP.

- Analog and digital feedback options include Resolver, EnDat 2.1/2.2, Hiperface, Hall A/B/I, SSI, and BiSS.

- An optional memory card helps parameterize or clone servo drives without a PC in a fraction of the time required using traditional commissioning software.

- A built-in "Safe Torque Off" (STO) function, per IEC/EN 61800-5-2, prevents motor operation while retaining ac input power. STO function helps minimize down time and provides faster restarts after incidents like emergency stops and normal operator access intervention. Machine operation can be restored quickly, without the need to reboot the drives or re-home the machine.

- An optional enhanced safety module, eSM, provides additional safety interlock functions, compliant with IEC/EN 61800-5-2. This can help free the user from having to engineer and certify complex safety concepts as required to meet federal and international regulations.



Jervah said, "The Lexium 32 servo drive range gives users the flexibility to select the drive and motor combination they need based on their machine's power, performance and functionality requirements, at a price point in line with the budget restrictions many machine builders now face."

The Lexium 32 servo drive range simplifies selection and adapts to various machine needs by offering three book-size servo drive models: the Lexium 32 Compact, Lexium 32 Advanced and Lexium 32 Modular. These servo drives are complemented by two motor families - the medium-inertia Lexium BMH and the low-inertia Lexium BSH. Each combination offers specific benefits and flexibility.

At a power density of nearly 550 Watts/L, the Lexium 32 servo drives are extremely compact and save users control cabinet space which reduces the machine footprint and decreases costs. They also feature optimized direct side-by-side cabinet mounting, an overload capacity of 400%, and enhanced motor control features such as vibration reduction, jerk limitation, two notch filters and other functions to optimize the life of the machine.

The products help machine builders reduce time-to-market, says Jervah. "This starts with proven tools for motor sizing, CAD and cabinet drawings. We then added PLCopen libraries, user-friendly commissioning software and integrated auto tuning functionality. All of this is in addition to the physical modification made to simplify wiring and installation."

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
