Allen-Bradley PowerFlex 523 AC drive

The Allen-Bradley PowerFlex 523 AC drive is designed to be suitable for builders of simple, stand-alone machines, balancing the need for ‘just enough’ control with a design that lowers total costs to design, develop and deliver machines.

Machine builders can use a standard USB connection for managing drive configuration files. They can also program the drive through its built-in human interface module (HIM), which displays data on the drive’s LCD with scrolling QuickView text and detailed explanations of parameters and other codes. AppView and CustomView tools help speed-up configuration by providing groups of parameters for common applications and by allowing users to save their settings to new parameter groups.

An optional dual port EtherNet/IP adapter supports ring topologies and provides device level ring (DLR) functionality, which can help provide network resiliency and improve machine availability. Adding a dual port EtherNet/IP adapter to a PowerFlex 523 AC drive also provides automatic device configuration, which saves time by automatically downloading configuration files when a drive is replaced.

The AC drive has a power range of 0.2-11 kW and motor control options including volts-per-hertz, sensorless vector control and Economizer mode in sensorless vector control.

The AC drive requires 50 mm of clearance on the top and bottom when installing into a cabinet. It is rated up to 50°C, and with an optional control module fan kit, the drive can withstand temperatures up to 70°C with current derating.
