Frequency inverters take on servo applications

The Lenze 8400 range of frequency inverters has been extended with the TopLine version, suiting applications with servo requirements, and with a power extension up to 45kW.

The 8400 range is already proven to give performance up to low-end servo levels, for example up to 180 cycles per minute with a standard asynchronous motor. Now the TopLine version takes on synchronous motors with performance advantages gained from the lower inertia of these models. By basing the design on a high volume inverter, TopLine gains large cost advantages compared to the alternatives of low cost servo drives. TopLine is the latest addition to the Lenze 8400 range and was unveiled at the SPS exhibition in November 2010. In-line with the lower specification StateLine and HighLine versions on which it is closely based, TopLine is available from 0.25 kW up to a newly extended maximum of 45kW. All three versions provide a compact solution for single or networked drives. Class-leading features include integrated filters, brake transistors, pluggable memory chip and CANopen.
