Weg's CFW11 frequency inverter incorporates Plug and Play technology automatically recognizing and configuring accessories and options used, allowing for easy installation of accessories and options. Incorporating Vectrue Technology™ allows WEG inverters to combine V/F, Sensorless Vector, VVW, and vector (with encoder) control techniques - all in one product. Aimed at increasing productivity, the CFW11 offers efficiency ratings greater than 97%, as well as innovations designed to improve motor control and operational functions for applications such as Multi Pump Control, Fans, Exhausts, Compressors, Paper and Cellulose / Wood, Cement and Mining, Oil and Gas, Iron Works and Metallurgy, Refrigeration, Sugar and Alcohol Production and many more!

WEG's CFW11 uses state-of-the-art technology to control motors up to 600HP with automatic control of the heatsink fan with speed sensor (additional protection) and easily detachable from the unit for cleaning and maintenance. Including Human-Machine Interface (HMI) with backlit graphic display and soft-keys, greatly facilitates inverter programming and operation. Aimed at increasing customers productivity, the CFW11 offers the following innovations:

• USB for microcomputer connection for using SUPERDRIVE programming and monitoring software as well as updating inverter firmware.
• DC link inductors (symmetrically connected to positive and negative DC link terminals) enable compliance with IEC61000-3-12 standard requirements
• Intelligent thermal management enables full protection of IGBTs, monitoring of heatsink and internal air temperature.
• Normal Duty and Heavy Duty ratings to adapt optimally to all kinds of loads.
• Protection with failure and alarm warnings.
• Motor overload protection in compliance with IEC 60947-4-2/UL 508 C.
• Memory card built into the standard product allows user to create functions without the need to use an external PLC (soft-PLC via IEC61131-3 programming software)
