Rockwell Automation
This company has expanded the power ranges and capabilities of the TotalForce technology for its Allen-Bradley PowerFlex 755T AC drives (photo). The drives now offer an expanded power range, from 10 to 6,000 h.p. (7.5 to 4,500 kW). The expansion brings harmonic mitigation, regeneration and common bus-system configurations to a wider range of high-demand applications. Enhancements to the patented TotalForce technology include more powerful 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 that can impact quality, waste energy and prematurely wear out a machine. In addition, predictive maintenance features provide realtime 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. — Rockwell Automation Inc., Milwaukee, Wis.
