WEG has launched a new frequency inverter CFW501 that has been designed to meet the needs of the heating, ventilation and air conditioning (HVAC) industry. The drives, which help users to optimise the operation of their motors, are currently available with a power range from 0.18 to 7.5 kW and are designed for applications in buildings, such as hospitals, schools and universities, for cooling and heating systems in commercial buildings, as well as for all pump and fan applications in general.
The CFW501 is based on the same modular plug and play platform as the CFW500 product family. The units include a built-in micro-PLC, programmable according to IEC 61131-3, and an intuitive HMI. The interface offers specific engineering units for HVAC applications, such as bar, mbar and m3/h, and is also available as a remotely controlled version for installation in a panel door. To allow for direct communication with the most important protocols in building automation, the CFW501 supports Bacnet, MetaSys N2 and Modbus-RTU.
Like the CFW500 drives, the new inverter can identify up to 64 different plug-in modules to connect to major fieldbus systems including Profibus-DP, DeviceNet and CANopen. Additionally, expansion plug-in modules are available enabling customisation for bespoke applications.
