Allen-Bradley PowerFlex 755T AC drives

Rockwell Automation has introduced a suite of drive solutions to help users reduce energy costs and increase machine uptime for assets running in high-demand applications. The drives provide harmonic mitigation, regeneration and common bus system configurations.

The TotalFORCE drive technology delivers motor control through precise, adaptive control of velocity, torque and position for electric motors.

All drives are compliant to the IEEE 519 specification and include comprehensive diagnostic and maintenance features, plus simplified start-up and installation.

The PowerFlex 755TL drive uses active, front-end technology and an internal harmonic filter to reduce harmonic distortion. The drive is available from 160 to 1250 kW.

Delivering power from 130 to 2300 kW, the PowerFlex 755TR drive includes both regenerative and harmonic mitigation solutions. The drive helps reduce energy consumption and costs by delivering energy back to the incoming supply, resulting in a more energy-efficient solution.

The PowerFlex 755TM drive system allows users to build the system that fits their needs for regeneration and coordination of multiple motors in common bus configurations. To optimise their system requirements and meet power consumption needs, users can select from a series of predesigned modules with a power range from 130 to 2300 kW.

The drive solutions have predictive diagnostics to estimate and provide notification of the remaining life span of drive components, such as fans, relay contacts, power semiconductors and capacitors. Users can actively monitor parameters, such as temperature and run time, of the drive and motor to allow for preventive action if necessary.
