presents the new Allen-Bradley PowerFlex 755 AC drives designed to provide industrial users with increased flexibility, advanced diagnostics and a common DC bus option.
Rockwell Automation has extended the power range of its PowerFlex 755 AC drives to 900 kW and added 600/690 volt ratings, making them suitable for use in heavy industrial processes.
Applications of the PowerFlex 755 AC drives range from simple variable speed and variable torque control to demanding systems requiring constant torque control. The AC drives are ideal for fans, pumps, mixers, compressors, conveyors and extruders.
An embedded Ethernet port and five option slots allow users to tailor the PowerFlex 755 to their specific requirements. Optional modules include I/O feedback, safety, additional communications and an auxiliary power supply.
A roll-out design allows easy access to the drive for fast installation and maintenance. The drive’s converter and control pod can remain in the unit while the inverter is rolled out ensuring that control wiring remains connected.
The firmware upgrade for PowerFlex 755 drives contains Interior Magnet Motor Control, which delivers increased application flexibility and high-energy efficiency. A Stop Dwell feature also helps prevent a motor from coasting to a stop, enabling users to preconfigure the motor to perform a controlled stop to help protect valuable motor investments.
