WEG High-Performance, Compact Size AC Drives from AutomationDirect

January 2, 2019

AutomationDirect has added a new line of AC variable frequency (VFD) drives for motor speed control and other industrial control applications.

The WEG CFW300 variable frequency drive is a high-performance VFD for three-phase induction motors. It is ideal for applications on machines or equipment that require precise control with easy setup and operation. The CFW300 features a compact size with contactor-style electrical connections (top in / bottom out). The VFD’s performance can be scaled to match the application by selecting WEG vector control (VVW) or scalar control (V/Hz).

The CFW300 includes a built-in keypad and SoftPLC with free WEG Programming Suite (WPS) software for custom tailored control schemes. The integrated WPS tool assists in the creation of automation applications, allowing graphical monitoring, parameter setting and programming in Ladder language (IEC 61131-3).

Built-in I/O capabilities include four configurable (PNP or NPN) digital inputs, one 0.5 A / 250 VAC relay output, and one 0-10 VDC / 4-20 mA analog input. A variety of plug-in option modules for additional I/O and communications protocols can be added to extend capabilities. A remote keypad and flash memory module are also available.

Starting at $138.00, sixteen units are available from 1/4 hp to 5 hp. Single-phase 100-127 VAC, and single or three-phase 200-240 VAC power supply options are available. WEG CFW300 series AC drives are cUL, CE approved and are backed by an 18-month warranty.
