Improved performance for medium-voltage drives
Earlier this year, this company introduced multiple enhancements to the Allen-Bradley PowerFlex 6000T medium-voltage drives (photo). The drives now include TotalFORCE technology, which provides precise control of speed and torque, diagnostic information for tracking system health and automatic adjustments to keep operations running smoothly. The PowerFlex 6000T drives follow speed or torque commands very closely in both open- and closed-loop vector control modes to deliver the precise control required for high performance and large loads. The drives also continuously monitor operations to track the health of electrical components in the drive and motor, and provide real-time diagnostic information to the control system. With this information, users can better predict maintenance requirements well before component failures and take action to prevent unplanned downtime. Additionally, adaptive control features within the PowerFlex 6000T drives help isolate potentially harmful vibration and resonances, and automatically compensate for variances to help keep applications running. — Rockwell Automation Inc., Milwaukee, Wis.n
