four quadrant variable frequency drives (regenerative AC drives)

As the leading manufacturer of drives, energy & controls solution, V&T EcoDriveCN® regenerative drives, which are also known as 4-quadrant inverters, incorporate an active supply rather than the passive diode supply used in conventional drives.

V&T EcoDriveCN® four quadrant variable frequency drives adopt the latest and most sophisticated motor control technology, use the energy regeneration of IGBT DC supply device, thus achieve the bi-directional control of rectifier energy feedback and the real four quadrant run.

V&T EcoDriveCN® regenerative drives are drives that operate in all 4 quadrants of power.

• Easy operation, programming and maintenance


• Robust construction


• V/F control, vector control


• Regenerative feedback(4-quadrant)


• Low harmonics, sine wave current


• Line voltage fluctuation compensation


• Multidrive common bus solutions


• Comprehensive motor protection package


• Engineered to industry standards CE, IEC and CCC


• Communication: Modbus, Profibus, CANopen


• High-speed fiber-optic interface

V&T EcoDriveCN® regenerative variable frequency drive converts regenerative energy into reusable power and feeds it back to the mains, and allows the AC motor drive to operate in four quadrants to decrease power consumption.

Application of V&T EcoDriveCN® four quadrant AC variable speed drives: conveyor belt, oil and gas, food and beverage, harbor machinery, mine hoist, crane for lifting cargo, pour-into washing machine, pharmaceutical machinery, multi-motors applications, centrifugal casting machine, centrifuges, high inertia application, and metal processing machinery such as large punching machine.
