Modular frequency inverters

The Lenze i500 frequency inverters on show bring a new standard to drives in a power range 0.25 to 45kW. The design concept “less is more” results in drives that are economic for simple applications but also modular so that higher functionality can be easily added. Dimensions are particularly compact leading to smaller panel sizes, a factor that is enhanced by the fact that no chokes or filters are needed on the vast majority of applications. The i500 is remarkably easy to get up and running, for example setting just 3 parameters can get the motor turning, so commissioning times are reduced. Furthermore the i500 is future-proofed with full international approvals and high efficiency to energy class IE2.

Also new to the UK is a major extension to the Lenze g500 range of frequency inverters. The current aluminium helical, shaft mounted helical and bevel ranges are all extended with new cast iron models for output torques above 10000Nm. Across the range there is wide flexibility on the specification, with features that used to be special becoming a standard option. For example motors can be IE1, IE2, IE3, inverter optimised or with terminal box inverters. To that can be added brakes, blowers, encoders plus gearbox oil and mounting options. This flexibility reduces costs and cuts delivery times.
