Drives Overview

The need for variable speed drives is increasing consistently, for example, in optimization of manufacturing and production processes or for saving energy.

The frequency inverters of the DF51, DF6, DV51 and DV6 series are ideally suited for this purpose. They match the required speed of a standard three-phase asynchronous motor to the drive requirements; be it as compact devices or modular system devices. They reliably assure the required sequence of movements of the drive motor and thus guarantee operational reliability and cost savings.

A high level of functionality need not be complex to operate: with their user-friendly design they feature – depending on the demands of the application – differing functional characteristics in a power range from 0.18 kW to 132 kW. Approvals from global standards allow them to be used worldwide.

DF51, DF6 – the versatile ones

[picture of industrial installation] DF51 and DF6 provide the economical solution for many machine and processing sequences for which it is sufficient to vary the rotational speed using a V/f control. Among these are pump and fan applications where the DF51 or DF6 inverters can contribute significantly to saving power and reducing cost. Functions, such as PID control loops or a thermistor input for motor protection, that normally require external components, are already built in. The devices can be used immediately, as they are supplied, without the need for programming, and the built-in keypad with setpoint potentiometer enables easy configuration and local operation.

DV51, DV6 – the powerful ones

[picture of industrial installation] DV51 and DV6 expand the scope of the DF series by numerous additional functions. Wherever more dynamics and higher torque levels are involved, the vector control provides the required motor torque at just the right moment. This brings safety and reliability of drives and optimum efficiency for the processing sequence. The various analog and digital configurable inputs and outputs offer a great deal of flexibility because they can be matched precisely to the requirements of individual machines and systems.
