EC: Allen-Bradley PowerFlex 755 AC drive

Motion Control - drives: Rockwell Automation, Allen-Bradley PowerFlex 755 AC drive. The expanded line of Allen-Bradley PowerFlex 755 AC drives provides users with expanded application flexibility, advanced diagnostics and excellent control system integration. This is a Control Engineering 2011 Engineers' Choice (EC) Award winner.


Allen-Bradley PowerFlex 755 AC drive from Rockwell AutomationMore flexibility, plus excellent control system integration is what users can expect from the expanded line of Allen-Bradley PowerFlex 755 AC drives. Building on the foundation of the PowerFlex 755 high-power models, the latest addition to this series extends the power range* to 450 kW/700 hp. Suited for heavy-industrial applications, these drives offer a market-leading roll in/out design to streamline installation and maintenance. The drive's modular design helps simplify replacement of drive components, such as cooling fans, circuit boards and major subassemblies. This modularity also allows the drive's converter and control pod to remain in the unit while the inverter is rolled out, so control wiring can remain connected. An additional advantage is the ability for the control pod in this drive to be mounted remotely for hassle-free access to low voltage control and diagnostics.

Advanced diagnostic capabilities include indication of blown fuses and blown surge protectors. Not only are these alarms reported to the main control to help ease troubleshooting, but they also provide essential protection inside the drive, helping to protect the customer's investment. The PowerFlex 755 drive comes equipped with an embedded Ethernet port and five option slots that allow users to tailor the drive to best suit their application. Options include I/O, feedback, safety, additional communications, and auxiliary control power input.    

PowerFlex 755 drives also support Rockwell Automation Integrated Motion, allowing complete support for drive configuration, programming, commissioning, diagnostics and maintenance in a single programming environment Rockwell Software RSLogix 5000 software. Common motion instructions for both servo and variable frequency drives are integrated into RSLogix 5000 software to deliver fast, convenient programming and a consistent user experience.
