THE new Allen-Bradley PowerFlex 40 ac drive, from Rockwell Automation , provides performance-enhancing motor control in an easy-to-use, compact package.

Available in 115, 230 and 460V for applications up to 7.5kW, the PowerFlex 40 features sensorless vector control to meet low speed torque demands, making it suitable for applications such as incline conveyors, extruders and constant torque pumps.

With flexible packaging options and an uncomplicated programming structure that is common to the PowerFlex 4 class of ac drives, the PowerFlex 40 can be quickly and easily installed and configured for a variety of applications.

The drive provides a number of options and features not typically available at the microdrive level.

In addition to sensorless vector control, the PowerFlex 40 is equipped with highly configurable I/O including the ability to perform basic logic, timer and counter functions.

The drive can also perform many advanced functions such as PID control and 'flying start', making it the most versatile product of its class.

To simplify programming, it has an integral keypad with the ten most commonly programmed parameters grouped together for fast and easy start up.

The PowerFlex 40 is also designed to accommodate internally mounted communication option cards, such as DeviceNet, in support of applications requiring advanced networking capability.

The drive features both DIN rail and panel mounting for ease of installation. Overall panel space can be reduced by taking advantage of the its 'Zero Stacking' capability, which allows drives to be mounted side by side.

Like all PowerFlex drives, the PowerFlex 40 is designed to meet worldwide power ratings and packaging requirements for out-of-the-box performance.
