The CFW-08 drives integrate the latest DSP (digital signal processor) and 16bit space vector modulation for optimised motor control and quiet operation.
WEG's CFW-8 range of compact drives has been extended and improved with new features including power ratings up to 15kW, an improved control card and new communication network interfaces such as CANopen and DeviceNet.
Designed for operation on centrifugal pumps, process dosing pumps, fans, exhausters, agitators and mixers, extruders and conveyor belts, the CFW-08 drives integrate the latest DSP (digital signal processor) and 16bit space vector modulation for optimised motor control and quiet operation.
The range of special functions available, combined with its flexibility and ease of use gives, the CFW-08 the ability to satisfy the broadest range of application demands across global markets.
It is aided in this respect by wide certification from world bodies CE, UL, C-TICK and IRAM.
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, multi-speed (up to eight speeds), maximum and minimum adjustable speeds, two skip frequencies and flying start.
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 multi-motor 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.
Extending the operating scope of the CFW08 range is a 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.
