Rockwell Automation presents Allen-Bradley PowerFlex 755T drives
By Renée Francoeur
January 5, 2017 – Rockwell Automation has introduced a suite of drive solutions, Allen-Bradley PowerFlex 755T drives, that it says will help users reduce energy costs and increase machine uptime for assets running in high-demand applications.
The Allen-Bradley PowerFlex 755T drives provide harmonic mitigation, regeneration and common bus system configurations. They also mark the introduction of “TotalForce” technology from Rockwell, which is motor control through “adaptive control of velocity, torque and position for electric motors”.
The expanded Allen-Bradley drive portfolio now includes the PowerFlex 755TL low-harmonic drive, PowerFlex 755TR regenerative drive, and PowerFlex 755TM common DC bus drive system, all compliant to the IEEE 519 specification. The three 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 also monitor parameters, such as temperature and runtime, of the drive and motor to allow for preventive action.
