Plug-in EMC filter for WEG’s CFW100 Mini Drive

WEG has launched an easy-to-install plug-in EMC filter to enable engineers to deploy the CFW100 Mini Drive in a wider range of simple engineering applications. The CFW100 Mini Drive is said to be the smallest variable speed drive with an integrated micro PLC currently available on the market and it can now be used with machines that are not necessarily equipped with a group EMC filter, including swimming pool pumps, lift doors and fitness equipment, as well as small fans, stirring and mixing machines and simple handling equipment.

WEG’s high performance EMC filter limits conducted interference and radiated high-frequency interference that are generated by the switching processes of the CFW100. The filters have been developed in line with the latest standards for adjustable speed electrical power drive systems and industrial, scientific and medical equipment. They are claimed to provide a reliable solution, preventing adverse effects on other nearby electrical equipment so they can continue to operate efficiently.

The EMC filter is suitable for all CFW100 frame sizes and can be installed without wiring or tools and mounted on the top-hat rail. As such, there is minimal downtime and no specialist personnel required for fitting the filter, saving users associated installation costs.

For further ease-of-use, plug-in extension modules are available for the Mini Drive, such as USB, Bluetooth and Modbus RTU communication interfaces, and modules for access to fieldbus systems, including Modus, DeviceNet and CANopen. Additional extension modules enable remote control.
