More IP65 inverters<br />

The Lenze AC Tech range of SMV frequency<br />

inverters with IP65 enclosure has been extended<br />

with 4 <strong>new</strong> powers up to 22 kW. The <strong>new</strong> models<br />

are at 11, 15, 18.5 and 22 kW and suit installation<br />

in wet and dirty environments, saving the cost<br />

of a panel enclosure.<br />

Matching the smaller models in the range, these<br />

higher power inverters feature the EPM memory<br />

chip, built in RFI filters and excellent sensorless<br />

vector performance. Communication options<br />

include CANopen, Ethernet IP, DeviceNet for the<br />

American market and PROFIBUS for Europe.<br />

Where inverters are to be installed outdoors,<br />

polycarbonate casings are available to give longterm<br />

résistance to UV. The SMV IP65 inverters<br />

have another strength with extremely compact<br />

dimensions. Even with their high protection<br />

casings, footprints are remarkably small – for<br />

example 204 x 254 mm at 7.5 kW.<br />

Small servo, large effect<br />

The second generation of 930K fluxxtorque servo drives<br />

has now made efficient, decentralised drive concepts<br />

feasible in the tightest spaces. With a power range of<br />

120 W to 440 W, the units are available for low and extralow<br />

voltages. In the course of product evolution, Lenze<br />

has also redesigned the synchronous servo motors used.<br />

Approximately 20 % less volume with the same power<br />

and increased efficiency speak for themselves. Added to<br />

that is extended functionality, including more control<br />

capabilities for actuators and sensors through the integrated<br />

digital and analogue I/Os, integration in EtherCAT<br />

networks, and feedback with single- and multi-turn<br />

absolute value encoders. In combination with the integrated<br />

positioning control, including a path program for<br />

processing up to 64 waypoints, the 930K fluxxtorque<br />

servo drive becomes a small, precise positioning drive.<br />

An expensive control system in the background is not<br />

Experts for<br />

Lenze Automation<br />

In early January 2010, Dr. Thomas Cord took<br />

over the management of Lenze Automation<br />

GmbH. He succeeds Frank Maier, who has<br />

joined the Board of Management of Lenze<br />

SE. With Dr. Cord, Lenze is pursuing its<br />

strategy of positioning itself more promi-<br />

nently as a specialist in automation tech-<br />

nology. “I am very pleased that we were<br />

able to attract Dr. Cord”, says Frank Maier.<br />

“His many years of experience and his expertise in marketing<br />

automation solutions will move Lenze a long way forward<br />

towards its goal of becoming a key player in the automation<br />

market.”<br />

Dr. Cord emphasises the central importance of his field for Lenze.<br />

“By merging control and drive technology, our customers will<br />

realise genuine added value through the clear simplification of<br />

the engineering solution.”<br />

necessary. The series can be operated easily and quickly<br />

with the free parameter setting software and the Speed-<br />

Tec connection system.<br />
