Allen-Bradley PowerFlex 755 drive system

The Allen-Bradley PowerFlex 755 AC drive boasts a range of features, allowing it to deliver more options for intelligent motor control and integration flexibility. With enhanced safety features, DeviceLogix embedded control technology, embedded ethernet connectivity and predictive diagnostics, the PowerFlex 755 is a functional motor control solution.

The PowerFlex 755 AC drive is available in power ranges from 7.5 to 250 kW at 400/480 VAC and 540/650 VDC input. It supports multiple languages, meets global standards and certifications, and is suited to many industries, including manufacturing, food and beverage, water/wastewater and materials handling.

The embedded Allen-Bradley DeviceLogix control technology optimises the drive’s performance and productivity, plus simplifies programming. Users have control flexibility to combine inputs and/or outputs and local logic functions to determine the drive’s behaviour. Moreover, the drive itself can process up to 90 function blocks with integrated instruction types to help configuration.

Two enhanced safety options are available: 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.
