January 19, 2010 — Schneider Electric announced Lexium 32 servo drive range with servo motors, providing machine builders exceptional performance, an unprecedented level of sophistication and outstanding power in a motion control solution. With three models to choose from, selection and use throughout a machine’s entire lifecycle is made easy, and costs are minimized by reducing cabinet space, time-to-market and interoperability into new or existing architectures.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.A host of features support rapid mechanical and electrical installation as well as maintenance of the drives and motors. This includes simplifying wiring by placing all connections either 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 also help users to customize the system based on their level of expertise (novice to advanced). Interoperability is significantly enhanced by allowing users to quickly integrate the Lexium 32 servo drives into new or existing architectures, regardless of supplier, by incorporating support for a wide variety of standardized hardware and software motion interfaces. Communication modules include 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. With an optional memory card, users can parameterize or clone servo drives without a PC in just 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. The 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.
