New PowerFlex 753 drive for optimised motor control
Rockwell Automation has introduced the new Allen-Bradley PowerFlex 753 AC drive - the latest addition to the company’s Allen-Bradley PowerFlex 750 series.
The PowerFlex 753 has been optimised for general purpose induction motor control applications, while maintaining the sophisticated functionality of the PowerFlex 750 series. With enhanced safety features, DeviceLogix embedded control technology and predictive diagnostics, the PowerFlex 753 provides industry with a highly functional and cost-effective motor control solution.
Available in power ranges from 0.75 to 250 kW at 415 V AC and 650V DC input, the PowerFlex 753 AC drive supports multiple languages, meets global standards and certifications, and is ideal for fan, pump and conveyor applications.
The PowerFlex 753 AC drive’s design incorporates a three-slot mechanical architecture that allows customers to tailor the drive with a combination of options - I/O, feedback, safety, communications and auxiliary control power - as their application requires. This, combined with the unit’s built-in I/O, provides users with increased operational flexibility.
The embedded Allen-Bradley DeviceLogix control technology in the PowerFlex 753 optimises the drive’s performance and productivity, plus simplifies programming. Users can incorporate PLC-style functionality within the drive, allowing standalone control if required. Furthermore, the PowerFlex 753’s predictive diagnostics capability minimises downtime by monitoring drive status - such as cooling fans, I/O relay cycles, motor run-time hours, and fault warnings - and allowing preventative action to be taken.
Two enhanced safety options are available in the PowerFlex 753: Safe Torque-Off or Safe-Speed Monitoring. Safe Torque-Off prevents drive restarts after the safety circuit is tripped. Safe-Speed Monitoring, on the other hand, combines this Safe-Torque-Off functionality with Rockwell Automation Safe-Speed Control core technology in one hardware option. Safe-Speed Control reduces and monitors the speed of an application to allow an operator to safety inspect and perform some process maintenance work without stopping the machine completely, thereby maximising productivity.
