Motors provide open-loop speed control
Rockwell Automation has extended the Allen-Bradley PowerFlex 700H power range to 500kW, and now offers the popular IP21 enclosure drive in two additional versions of IP54 dust tight enclosure and open-frame IP00 option. More flexible than ever, the PowerFlex 700H is the ideal choice in an even wider variety of open-loop speed control applications. Since its introduction last year, the PowerFlex 700H has proved a popular choice in applications requiring accurate open-loop speed regulation and excellent low-speed torque, such as fans, pumps, conveyors, mixers, crushers, bark strippers, centrifuges, stamping presses and extruders.
With the addition of the new IP54 enclosure option, it can now be employed in an even wider range of applications, in all but the harshest industrial environments.
Along with the existing IP21 enclosure and new IP54 enclosure, Rockwell Automation has also added an IP00 option to the PowerFlex 700H.
The open frame design makes the PowerFlex 700H more accessible than ever to OEMs and machine builders requiring precise, reliable and cost-effective motor control for their high-power applications.
Open frame access and 'pull-apart' control terminal blocks simplify the task of wiring, and the optimised global voltage settings make the drive quick and easy to configure for applications anywhere in the world.
The power range of PowerFlex 700H has now been extended to offer 160kW to 500kW at voltages from 380 to 690V.
Users can configure the PowerFlex 700H for either V/Hz or sensorless vector control.
Standard I/O options include 24V or 115V digital I/O plus analogue I/O for added flexibility.
The extensive communications options available allow the user to easily integrate the drive into a manufacturing process or machine application using Rockwell Automation NetLinxTM, DeviceNetTM, ControlNetTM and EtherNet/IP networks as well as other industrial networks such as Profibus.
The built-in LCD display is multi-line and multi-lingual, and the on-board start and assisted start routines allow for easy configuration and tuning of the drive.
Naturally, PowerFlex 700H is also fully compatible with Allen-Bradley DriveExplorer, DriveExecutive and DriveTools SP software tools, making complex programming and system configuration easy and quick.
The new PowerFlex 700H IP54 enclosure and IP00 open-frame options are just the latest additions to the comprehensive PowerFlex range of AC drives, available from 0.25kW to 6700kW.
Like all products within the PowerFlex family, the 700H meets worldwide power ratings, packaging requirements and electromagnetic compatibility (EMC) criteria.
All the drives include AC-chokes and EMC filters compliant with EN 61800-3, and are CSA/cUL Certified, UL-listed and CE-marked.
The modular design and worldwide availability of spares makes the PowerFlex range easy to maintain in the field.
With the power range extension and addition of IP54 and IP00 variants, PowerFlex 700H is the ideal choice for both OEMs and end-users requiring the best possible combination of features and cost-effectiveness.
