Allen-Bradley PowerFlex 755 AC drives extended power range

The power range of the Allen-Bradley PowerFlex 755 AC drives has been expanded to 450 kW, providing users with increased application flexibility. The drive is suitable for motor control applications in a variety of heavy industries, including oil and gas, tyre and rubber, refining, material handling, metals and mining.

The drive’s rollout capability allows easy access to the drive for fast installation and maintenance, and its modular design helps simplify replacement of drive components, such as cooling fans, circuit boards and major subassemblies. This 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 easy access to low-voltage control and diagnostics.

Its 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, they also provide essential protection inside the drive. Monitoring and tracking operating data on cooling fans, I/O relay cycles and motor run times also provides valuable data for preventative maintenance.

The 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.

The drive supports Rockwell Automation Integrated Motion, allowing it to be configured and controlled using motion profiles and instruction sets in an Allen-Bradley ControlLogix controller with RSLogix 5000 software.
