No compromise from compact drives

WEG reckons its new CFW-08 range of compact drives is proof positive that users don't have to compromise on drive size, performance, ease of use or price.

WEG reckons its new CFW-08 range of compact drives is proof positive that users don't have to compromise on drive size, performance, ease of use or price.

Catering for single-phase applications from 0.18 to 3.7kW, and three-phase applications from 0.25 to 7.5kW, the highly compact CFW-08 integrates the latest DSP and 16bit space vector modulation for optimised motor control and quiet operation.

The CFW-08 operates in two control modes, V/F and sensorless vector, and packs in a host of special features for the user, including "S" acceleration and deceleration ramps, local remote control, DC braking, torque boost, motor slip compensation, JOG, ride through, multispeed (up to eight speeds), maximum and minimum adjustable speeds, two skip frequencies, flying start and many more.

The first of the CFW-08's control modes, V/F, is suited to variable torque loads and includes a selectable energy saving feature, which reduces motor losses when operating at lower speeds.

This control mode also permits the drives to operate in multimotor applications where more than one motor is supplied by a drive.

The alternative operating mode, sensorless vector control, allows the drive to precisely control the speed and torque of a motor, enabling the CFWO8 to be used on demanding duties such, as extruders, conveyors and rewinders etc.

Extending the operating scope of the CFW08 range is a comprehensive range of options, providing maximum application flexibility.

These include Superdrive, WEG's own software program for drive control from a PC or PLC, and RS232 and RS485 communication modules.
