The PowerFlex525 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 designed 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.

The PowerFlex 525 AC drive offers 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 speeds up commissioning time.

Removing the control module from the power module further reduces startup 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 optimizes 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 minimize production losses. The drive’s economizer mode helps optimize motor energy consumption by monitoring an application’s current demand and automatically refining operating parameters accordingly.

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.
