The new Lenze 8400 range of frequency inverters is extended with new models and features. Within the range are the simple and low-cost BaseLine models up to 3kW, the standard StateLine models up to 11kW and the new HighLine models with integrated point-to-point positioning, also up to 11kW. Space-saving mounting options are available and approvals include UL and RoHS.
Control panel size can be reducing by choosing from two available options on the 8400 range. ‘Cold plate’ versions are supplied without a heatsink and therefore have a reduced depth by 35mm. The surface onto which the inverters are mounted needs to have a high thermal mass or be externally cooled. The same depth reduction can be achieved by ‘Push through’ versions where the inverter heatsink sits outside of the control panel. Not only does this save panel space, but it reduces panel cooling requirements as the majority of the lost energy is external to the cabinet.
8400 StateLine and HighLine models have a CANopen port integrated as standard. The new HighLine models are recommended for applications such as rotary indexing tables, roller doors and positioning tasks in warehouse systems. Up to 16 position destinations, including the associated travel profiles, can be stored in the inverter. High positioning accuracy is achieved by evaluation of a two track encoder signal at up to 100Hz.
The 8400 frequency inverter range is part of the Lenze L-force product portfolio. Integrated and standard CAN connections allow simple connection to other drives and devices such as I/O and HMI. Additional fieldbus connections such as PROFIBUS can be added as a plug-in option. The wide range of models and functionality leads to selections that are ‘Rightsized’ for the application, saving money and increasing performance.
