With a launch at the April Hannover Show, Lenze announce the new L-force 8400 frequency inverter, a modular range of tailored drive solutions that let you select the “Rightsize” for your needs.  Initially available as 1-phase models up to 2.2kW and 3-phase up to 11kW, the range will rapidly expand into higher powers.  As part of the Lenze L-force portfolio, easy integration into Lenze control systems is assured.

Customers pay only for the features and functionality they need.  The modular approach initially covers three designs.  The Baseline is the entry level model of the series in terms of functionality and drive behaviour.  This modern and all-purpose frequency inverter is the unit of choice when handling drive tasks with steady movement, as is the case with conveyor drives, pumps, blower and fans.

The StateLine is best suited to drive solutions with and without speed feedback.  It is therefore used for applications that require networking across bus systems.  With integrated brake control, integrated PID, flying restart circuit and further features, StateLine is the solution for controlled movement.

The HighLine version includes added functionality for more complex tasks. In particular, software is built in for positioning and indexing. All three versions have the same dimensions and fixings to aid panel design. Furthermore all versions feature a pluggable memory module that holds all the parameter settings. This feature allows off-line programming, easy software updates and makes exchanging an inverter into a simple task.

L-force engineer software at the entry level is free of charge and customers can opt for more powerful versions if they need the extra functionality.  CANopen is integrated and other pluggable fieldbus modules are optional extras.

Many more cost saving features are available with the 8400 inverters such as Safe Torque Off, operation with IT mains and RoHS compliance.  Performance is second to none with 200% overload capacity, very fast response, S-ramps and a 45°C ambient rating without derating.  The modularity of the 8400 range, and the ability to match the drive to the need, leads to a “Rightsize” selection saving costs and optimising performance.
