Allen-Bradley PowerFlex 6000T medium-voltage drives

Rockwell Automation has announced that its Allen-Bradley PowerFlex 6000T medium-voltage drives now include TotalFORCE technology, which is designed to provide precise control of speed and torque, diagnostic information for tracking system health, and automatic adjustments to keep operations running smoothly.

The drives follow speed or torque commands closely in both open- and closed-loop vector control modes to deliver the 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 drives are said to help isolate potentially harmful vibration and resonances, and automatically compensate for variances to help keep applications running. With load-observer technology, they also effectively reject disturbances when loads change suddenly, helping to keep operations running smoothly and increasing output.
