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

Already proven to give performance up to low-end servo levels, now the Topline version of the 8400 range 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.

In line with the lower specification Stateline and Highline versions on which it is closely based, Topline is available from 0.25kW up to an extended maximum of 45kW.

All three versions provide a compact solution for single or networked drives.

Features include integrated filters, brake transistors, pluggable memory chip and CANopen.

Optional field buses are Profibus, Profinet, EtherCAT and Powerlink.

Topline adds to these features the ability to control synchronous motors and increased feedback options allowing it to take on the majority of servo applications.

Compared to standard asynchronous motors, synchronous servo motors have a much lower inertia, typically by 65 per cent or more.

The 8400 Topline drive has matching feedback option for synchronous motors and connects to resolvers, TTL incremental and SSI absolute encoders.

It is designed for repetitive positioning tasks such as pick and place, also storage and retrieval units, 200 per cent overload is available for three seconds and, depending on application data, performance of up to 300 cycles per minute with 0.01mm accuracy can be achieved.

In complex and multi-axis machinery, Topline is easy to integrate.

One software application, Lenze L-force Engineer free of charge in the basic version, allows set up of all the 8400 inverter range together with Lenze controllers, I/O and HMI.

The new 8400 Topline is available in 16 power levels from 0.37 to 45kW allowing designers to closely match their requirements.

Users benefit from the compact dimensions and ease of use, but the biggest gain is in the purchase cost arising from the low-cost inverter-design base.

Integrated features such as filters and brake transistors save further space and costs.
