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.
