Rockwell Automation has unleashed its Allen-Bradley PowerFlex 525 AC drive to help machine builders and end users simplify equipment design and operation, and speed installation and configuration. According to the company, the drive features a modular design in power ranges from 0.5-30hp or 0.4-22kW at 100-600V input. Its embedded EtherNet/IP, safety, USB programming, energy savings and a variety of motor-control options are geared for machine-level and stand-alone applications or simple system integration, added the firm.

Aimed at applications such as 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, Rockwell Automation indicated.

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 customise for a machine. Using a standard USB connection, machine builders can download easily the completed configurations and share with multiple drives, which greatly speeds commissioning time.

Removing the control module from the power module further reduces start-up time because configuration and installation can be done simultaneously. MainsFree programming through a USB connection removes the need for main power during drive configuration, as well as the need for special adapters to communicate between the drive and the programming tools.

Embedded EtherNet/IP connectivity optimises integration with programmable controllers to deliver more application flexibility. Optional dual-port EtherNet/IP connectivity supports device-level ring (DLR) topology, providing a robust network infrastructure.

An SIL2/PLd-certified, embedded safe torque-off feature helps prevent drive restarts after a safety circuit is tripped, ultimately helping to protect personnel and equipment, and minimise production losses. The drive's economizer mode helps optimise motor-energy consumption by monitoring an application's current demand and automatically refining operating parameters accordingly.

The PowerFlex 525 AC drive requires 50mm 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 50C. With an optional fan kit, the drive can withstand temperatures up to 70C with current derating.
