AC Drives

Rockwell Automation has expanded the power range of its Allen-Bradley PowerFlex 755 AC drives to 450 kW/700 HP providing users with increased application flexibility. Featuring advanced diagnostics and a convenient roll-out design, the PowerFlex 755 AC drive is well-suited for motor control applications in a variety of heavy industries, including oil and gas, tire and rubber, refining, material handling, metals and mining. A key feature is its roll-out capability, which allows easy access to the drive for fast 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. Monitoring and tracking of operating data on cooling fans, I/O relay cycles and motor run times also provides valuable data for preventive maintenance, helping to reduce unplanned downtime. This power range extension expands the PowerFlex 755 AC drive offering from 0.75 kW (1 HP up to 450 W and 700 HP at 400/480 V AC input, providing robustness, ease of use, flexibility and performance in a single product family.
