Rockwell Automation Expanded power range for ac drives
The Allen-Bradley PowerFlex 755T ac drives offer an expanded power range to accommodate applications from 10 to 6,000 hp (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 compensate automatically for the changes that occur. An adaptive tuning feature uses as many as four automatic tracking notch filters to block resonance and vibration that can impact quality, waste energy and wear out a machine prematurely.
