Simplified Functionality and Reliability

New WEG Micro Drive Offers Simplified Functionality and Reliability in an Ideal, Low-Cost OEM Package.

WEG has introduced the ideal micro drive for OEMs and users, the new CFW10 providing all the performance features expected from a modern variable speed drive - including digital signal processing - in a package believed to be smaller, lower cost and easier to use than other drives in its class.

"With the introduction of the CFW10 WEG can now offer users a motor and drive package for under 100 pounds sterling," said Andrew Stevens, WEG's Product Manager for Drives.

"What's more, as the CFW10 is single- phase input with three-phase output, the OEM or user does not have the cost and unreliability problems associated with single-phase motors".

"Instead he gets a WEG package that is warrantied for 3-years".

The CFW10 is the ideal product for users and OEMS seeking reliability and reduced functionality from a drive at reduced cost.

Available in three frame sizes, in the power range 0.12 to 2.2Kw, and offering easy mount fixings, the drive has a reduced number of parameters and is pre-programmed and ready to run, thus saving both programming and installation costs for the OEM.

"What we are offering users as a result of pre-programming of the CFW10 is essentially a 'Quick Start Guide'," said Andrew Stevens: "connect power, connect motor and press start; it's as simple as that".

Despite its size and simplicity, the CFW10 has all the performance features expected from a modern variable speed drive.

The unit is designed with a digital signal processor, for high-speed performance and fast response, uses SMD componentry and the latest generation of IBGTs to achieve considerable reductions in motor noise.

The unit is equipped with a membrane keypad for simplified local programming and offers several special functions as standard, including S type linear ramp and secondary ramp, a JOG function, separate acceleration and deceleration ramps, DC braking, a multi-speed function offering up to eight programmable speeds, adjustable linear and quadratic V/F curves, slip compensation, manual and automatic IxR, and many more.

The low cost, simplified functionality and high reliability of the CFW10 drives make the units ideally suited to a wide range of applications including pumps and fans, stirrers and mixers, driers, cutting machines, rotating filters and extruders.

When a CFW10 drive is purchased with a WEG motor, the resulting package qualifies for the 3-year warranty, which WEG has introduced on all its UK supplied motors and drives when provided as packages (motor + drive).

This guarantee provides users with greater security of purchase and a single source responsibility for the equipment, which, with WEG's extensive UK distribution network is usually situated locally.

The CFW10 is an addition to the existing WEG range of variable speed dives and soft starts.

Variable speed drives are available from 0.12kW to 1.3MW at 400v, and 690v and 1.8MW in medium voltage options.

Soft starts are available from 1.1kW to 1.9MW and are available with or without by pass contactors.
