NEMA 4X rated variable frequency drives (VFD) enable speed control for three-phase AC motors such as those in conveyors, fans, pumps, and material handling, and are suitable for washdown-duty applications. They offer V/Hz, sensorless vector or field oriented vector control up to 30hp. A full line of accessories ensures a reliable installation.
WEG CFW500 series drives are high-performance AC variable frequency drives that support closed-loop flux vector speed control as well as torque control modes and can operate both AC Induction motors and permanent magnet AC motors. These models are offered in an IP66/NEMA 4X enclosure up to 20 hp. Drives with high-performance features such as these have typically had long lead times, but now you can get them shipped direct from stock at AutomationDirect.com.
The CFW500 provides a broad range of input voltages and horsepower models to select from
Control Modes include Scalar, Vector Control (Sensorless and closed-loop with encoder feedback), and VVW PM (suitable for fan, pump and compressor)
Advanced control features are available for applications where you need more than basic accel & decel.

The ACN series of NEMA 4X sensorless vector AC drives bridge the gap between a micro drive and high-performance VFD. These AC drives have features normally only found on more expensive drives, in a NEMA 4X enclosure and at a great price.
These drives offer an advanced remote keypad, Ethernet option cards so the drive can communicate over Modbus TCP and EtherNet/IP, and the option to configure and program using the free, user-friendly VFD Suite software.
ACNxx series drives support 4 control modes which include V/Hz, slip compensation, sensorless vector and torque control.
The DURApulse GS20X new generation high performance vector control drives provide many standard and advanced functions - all in a compact unit that has been reduced 40% in size. The NEMA 4X version provides service in the harshest of environments.
The drives include many of the same standard features as our GS family of drives including dynamic braking, PID, and RS-485 Modbus communication.
The GS20X drive expands the DURApulse family by adding single-phase input capability (ALL 230VAC drives can be supplied single-phase), a built-in PLC, and optional EtherNet/IP and ModbusTCP communication card. The drive supports up to four (4) independent IM motor parameter sets or supports control of a single AC PM motor.
DURApulse GS20X AC drives offer several different speed control modes: standard V/Hz with pulse input feedback, sensorless vector (SVC) for Induction Motors (IM) and Permanent Motors (PM), and ultra-precise Field Oriented Vector control (FOC) for maximum open loop speed regulation control.
