The Vectrue Technology represents a significant advancement, allowing this new generation of WEG inverters to combine V/F, Sensorless Vector and Closed Loop Vector (with encoder) control techniques, all in one product. An innovation was also introduced to simplify applications that require braking torque. A new feature named Optimal Braking eliminates the need for the dynamic braking resistor in some applications allowing a simpler, more compact and economical solution. Dimensions (H x W x D): 210 x 143 x 196mm. Weight: 3.5kg. Variable Speed Drives The WEG CFW series is intended for speed control of three-phase induction motors. Applications: Centrifugal Pumps, Process Pumps, Fans/Exhausters, Stirrers/Mixers, Extruding Machines, Conveyors, Roller Tables, Granulators, Pelletising Machines, Driers, Rotating Ovens, Rotating Filters, Winders, Unwinding Machines, Cutting and Welding Machines.
