Micro AC Drive Units

WEG CFW300 Series AC Sensorless Vector Drives

WEG CFW300 variable frequency drives are high-performance VFDs for three-phase induction motors. They are ideal for applications on machines or equipment that require precise variable-speed control with easy setup and operation.

The CFW300 series features compact size and includes a built-in operator interface (HMI) and SoftPLC with free WPS programming software. A variety of plug-in option modules for additional I/O and communications protocols can be added to extend capabilities.
