Rockwell Automation Allen-Bradley PowerFlex 525 AC Drive

Rockwell Automation’s compact Allen-Bradley PowerFlex 525 AC drive helps machine builders and end users simplify equipment design and operation, and speed-up installation and configuration. The drive features a modular design in power ranges from 0.5-30 hp or 0.4-22 kW at 100-600 V input. Suitable for a range of applications, including conveyors, material handling, compressors, fans and pumps, the drive provides a variety of motor control options to accommodate open- and closed-loop applications.

To help streamline set-up, users can configure the drive through its human interface module, Rockwell Automation Connected Components Workbench software or Rockwell Software Studio 5000 Logix Designer. The drive offers time-saving application sets - groups of predefined 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 the completed configurations and share with multiple drives, speeding up 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 topology, providing a robust network infrastructure. A SIL2/PLd-certified, embedded safe torque-off feature helps prevent drive restarts after a safety circuit is tripped, protecting personnel and equipment and minimising production losses. The drive’s economiser mode helps optimise motor energy consumption by monitoring an application’s current demand and automatically refining operating parameters accordingly.

The drive requires 50 mm of clearance on the top and bottom when installing into a cabinet and can be mounted zero-stacked both horizontally and vertically. The smaller clearance can help users reduce the panel space required for their application. In addition to the flexible installation, the drive is rated up to 50°C. With an optional fan kit, the drive can withstand temperatures up to 70°C with current derating.
