Rockwell Automation announces expansion of TotalFORCE capabilities and power range for PowerFlex 755T drives

November 9, 2018 — Rockwell Automation has expanded the power ranges and capabilities of TotalFORCE technology for its Allen-Bradley PowerFlex 755T AC drives. The drives now offer an expanded power range, for engineers with applications from 10 to 6,000 horsepower (7.5 to 4,500 kW). The expansion brings harmonic mitigation, regeneration and common bus-system configurations to a range of high-demand applications.

Enhancements to the patented TotalFORCE technology include adaptive control capabilities, which allow the drives to monitor machine characteristics that can change over time and automatically compensate for the changes that occur. An adaptive tuning feature uses up to four automatic tracking notch filters to block resonance and vibration.

In addition, predictive maintenance features provide real-time information about the health of the drive. By monitoring operational characteristics such as temperature, voltage and current, the drive is able to calculate the remaining life of critical components and notify users.

The PowerFlex 755T variable-frequency drives were previously designed for 160 to 3,000 horsepower applications. The power range makes PowerFlex drives suited for large power applications, such as pumps and fans requiring harmonic mitigation, and regenerative applications requiring anti-sway functionality, such as cranes and hoists. The offering includes:

  • PowerFlex 755TL drive: The PowerFlex 755TL drive uses active front-end technology and an internal harmonic filter to reduce harmonic distortion. The drive is now available from 10 to 1,800 Hp (7.5 to 1,400 kW). 
  • PowerFlex 755TR drive: Delivering power from 10 to 6,000 Hp (7.5 to 4,500 kW), the PowerFlex 755TR drive includes both regenerative and harmonic mitigation solutions.
  • PowerFlex 755TM drive system: This allows users to build the system that best fits their needs for regeneration and coordination of multiple motors in common bus configurations. Users can select from a series of predesigned modules with a power range from 250 to 6,000 Hp (160 to 4,500 kW) for motor side inverters and a range of 70 to 4800 kW for regenerative bus supplies.

Other capabilities include an integrated safety module that delivers several safety functions on an EtherNet/IP network, an anti-sway feature that helps lifting applications achieve stability and permanent magnet motor control.
