10 A growing family of decentralised inverters The 8400 protec series from drive and automation specialist Lenze made its debut at the SPS/IPC/ Drives 2009. It has been only a few months since that event, and already there are additions to the family. The 8400 motec motor inverter is the latest useful addition to this range of products. With its functionality, this compact version marks an advance in decentralised drive technology that is a victory particularly for intralogistic enterprises such as warehouse & airport businesses. Mechanical engi- neers in general are also enthusiastic about its clean, ergonomic design.

An efficient platform: the 8400 motec and 8400 protec bring decentralisation to the 8400 inverter drive series While the 8400 protec incorporates safety technology that offers an impressive array of functions and easy-touse diagnostic capabilities, the <strong>new</strong> 8400 motec scores points with its compact and economical <strong>structure</strong>, not to mention its successful combination with a geared motor and flexible options, which Lenze offers as a complete “drive package”. Something for everyone The products in the 8400 series of inverters have been designed with the demands and wishes of our customers in mind and are therefore available at present in two versions with different functional specifications. The following design types are currently available: • 8400 protec, designed for 0.75 to 4.0 kW, with interfaces for CANopen and PROFIBUS/PROFINET • 8400 motec, 0.37 to 1.5 kW, with AS-i, CANopen and PROFIBUS (powers will steadily increase) Common strengths Despite the differences in their features, the individual members of this family of products have much in common, as one would expect. They all reflect Lenze’s emphasis on compatibility, user friendliness, and efficiency on all levels. Because its connection system is designed for compatibility, for example, the same plug connections can be used for mains, fieldbus, and safety components. Their operation is handled uniformly through the same keypad, commissioning and diagnostics through Lenze’s L-force Engineer software. Users are also sure to be pleased by the strong “plug & drive” concept inherent in these units, which are always “ready to use” thanks to their factory-installed options and available accessories. Use of this product family becomes even more compelling when one considers that its comprehensive system compatibility increases efficiency more or less automatically. The 8400 motec drive package Thanks to the precisely matched set of components – motor, gearbox and inverter – the 8400 motec motor inverter is a compact, energy-efficient package that offers the best “cost per kW” values. The drive package consists specifically of the following components and their advantages as described: • L-force 8400 motec Mounting directly on the motor yields cost advantages resulting from, for example, elimination of the shielded motor cable. The integrated VFCeco energy-saving func- tion enables a substantial increase in motor efficiency in partial load operation. • L-force MF three-phase AC motor These motors, which are specially optimised for inverter operation, are up to two frame sizes smaller than traditional three-phase AC motors. They exceed the minimum efficiency ratings for efficiency class IE2 and have a wide range of speed settings. • L-force gearbox Mounting the right-angle and coaxial gearboxes on the motor creates an extremely compact unit. The high efficiency of the gearbox reduces energy losses to almost negligible levels. System integration Even the base unit provides extremely cost-efficient support for looping through 400 V. The large selection of built-on modules makes this possible even for the plug-in version, both when it is in motor mounting position and when it is mounted on a wall near the motor. As a result, any number of installation concepts can be quickly and easily implemented. Simple commissioning The 8400 motec is designed for commissioning without the use of PC software, thanks to the three potentiometers and DIP switch that are installed. But even tricky problems can be resolved, thanks to the keypad and the L-force Engineer. The easy-to-see illuminated surface makes a quick initial diagnosis possible even under difficult installation conditions. teChnologY 11
