Representing the first drive from the new Allen-Bradley PowerFlex 750 series, the PowerFlex 755 ac drive meets global user needs for versatile motor control , integration ease and high performance to help increase productivity .
Available in power ranges from 7.5 to 250 kW or 10 to 350 hp at 400/480 V ac and 540/650 V dc input, the PowerFlex 755 ac drive supports multiple languages, and meets global standards and certifications.
It is suited for many industries, including converting, automotive, machinery, food and beverage, material handling, metals, mining, and tire and rubber.

The drive offers a broad range of functions and options:

  • Allen-Bradley DeviceLogix control embedded in the drive gives users control flexibility to combine inputs and/or outputs and local logic functions to determine the drive’s behavior.

  • Embedded Ethernet allows users to easily configure, control and collect drive data over EtherNet/IP networks.

  • To minimize downtime, users can configure the drive to provide advanced notification of operating data on cooling fans, I/O relay cycles, motor run-time hours and potential fault warnings.

  • Embedded Safe Torque-Off and Safe-Speed Monitoring safety options help customers reduce overall system costs while helping to protect personnel and equipment, and improve productivity.

Engineers designed the PowerFlex 755 ac drive with a slot-based mechanical architecture that allows customers to tailor the drive with as few or as many options– I/O, feedback, safety, communications and auxiliary control power – as the application requires.
