Variable speed drive with embedded micro-PLC

WEG's new CFW500 range of inverter drives has been designed to deliver 'exceptional' performance for three-phase induction motor control.

The devices, available in power ratings from 0.18 up to 22kW, are said to offer a high level of control, enabling industrial manufacturers to improve processes and make significant cost savings. They are based on modular plug and play design and are suitable for industrial automation applications such as centrifugal and process pumps, fans, compressors and conveyors. The drive includes a built-in micro-PLC, which can be programmed according to standard protocol IEC 61131-3. It also comes with pre-programmed macros for a range of applications, for example positioning, timer and acceleration. Users can programme the drive using the LCD HMI display, or via a computer through a variety of interfaces (RS232, USB, RS485).
