Next-generation AC drive
By Alison Dunn
Rockwell Automation recently launched its compact Allen-Bradley PowerFlex 525 AC drive to help machine builders and end users simplify equipment design and operation, and speed installation and configuration. Representing the first in the company’s next generation of compact drives, the PowerFlex 525 AC drive features a modular design in power ranges from 0.5 to 30 horsepower or 0.4 to 22 kilowatt at 100 to 600 volt input. Its embedded EtherNet/IP, safety, USB programming, energy savings and a variety of motor control options are ideally suited for machine-level and stand-alone applications or simple system integration. Suitable for a wide range of applications, including conveyors, material handling, compressors, fans and pumps, the PowerFlex 525 AC drive provides a variety of motor control options to accommodate open- and closed-loop applications. To help simplify and streamline setup, users can configure the PowerFlex 525 AC drive through its human interface module (HIM), Rockwell Automation Connected Components Workbench software or Rockwell Software Studio 5000 Logix Designer. The PowerFlex 525 AC drive offers time-saving application sets, which are groups of pre-defined parameters for common drive applications that users can apply “as is” or customize for a machine. Using a standard USB connection, machine builders can easily download the completed configurations and share with multiple drives, which greatly speeds up commissioning time. The PowerFlex 525 AC drive requires 50 mm (2 inches) of clearance on the top and bottom when installing into a cabinet and can be mounted zero-stacked both horizontally and vertically. This smaller clearance can help customers reduce the panel space required for their application. In addition to the flexible installation, the PowerFlex 525 AC drive is rated up to 50 C (122 F). With an optional fan kit, the drive can withstand temperatures up to 70 C (158 F) with current derating.
