WEG Electric Introduces the CFW500 Machinery Drive

Atlanta, GA – WEG Electric introduces its new CFW500 variable frequency drive loaded with features machinery designers, OEM’s and end users want.  The CFW500 is the most recent addition to WEG’s complete line of variable frequency drives. WEG’s engineers specifically designed this new drive with increased features that focus on the machinery manufacturer’s needs. It is simple, efficient, flexible and can be commissioned quickly and easily.

The WEG CFW500 drive has 230Vac power ratings of 1/4HP-3HP Single-Phase input; 1/4HP-15HP Three-Phase input, as well as 1/4HP-25HP 3 Phase input at 460Vac. Key features include V/Hz and vector control (VVW) operating modes, a built-in PLC, integrated keypad with back lit display, optional external flash memory module, and ‘plug and play’ option modules for communications and I/O to accommodate numerous machine configurations.

The CFW500 is designed to operate in ambient temperatures up to 50°C and can supply an overload of 150% for one minute, repeatable every 6 minutes without derating. This capability eliminates the need for the machine designer to oversize the VFD.

In addition, the CFW500 is designed to follow a pulse train signal as its speed reference and also transmit a pulse train through its digital output making it ideal for master/slave or matched speed applications.
Programing and viewing drive parameters is simple with the built in keypad. 

The backlit display is capable of monitoring up to three different variables at the same time, along with indication of operation status, alarms and faults. A remote keypad CFW500-HMIR connected through a USB cable can be used in a local or remote location, and can be selected to serve as an external control device or locked to prevent unauthorized operation. The CFW500 drive is also compatible with WEG Superdrive G2 programing control software, available as a free download from www.weg.net.

The built-in fully programmable Soft PLC is ideal for managing an OEM’s machine logic control needs. It includes a P-I controller for control loops, a sequencing control for progressive machine processes along with numerous logical functions, eliminating the need for an external PLC. The programs saved in the CFW500 memory can also be password protected to secure the OEMs intellectual property.

Using the CFW500-MMF Flash Memory Module you can save the drive parameters and PLC code for back up and transfer to another drive as well as performing repetitive drive programing when assembling multiple duplicate machines. Powered by internal batteries, the Flash Memory Module has a capacity for over 5000 operations and can be used without applying power to the VFD making it safe to work with.

Flexibility is enhanced with a full complement of plug-in communication and I/O modules allowing streamlined interface of the standard VFD to meet specific application requirements.

The CFW500 is supplied as NEMA 1 rated enclosure. An integral dynamic braking (IGBT) feature is available in B frame drives and larger and a factory installed RFI filter is available which reduces electromagnetic interference.
Along with all these features you also receive WEG quality advantages. Each CFW500 is tested under load at the factory, has protection against ground fault, short circuit and over temperature and all are manufactured with conformal coated circuit boards classified as 3C2 per IEC specification 60721-3-3.
