CFW-09 (1 - 500 HP)

The WEG CFW-09 Series of Variable Frequency Drives incorporate the world’s most advanced technology in drives for three-phase AC induction motors.
The Vectrue Technology™ represents a significant advancement, allowing this new generation of WEG VFD’s 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 economic solution.
