Rockwell Automation Improves Security, Performance and Commissioning with PowerFlex 755T AC Drive Enhancements

Industries such as pulp and paper, automotive, tire and rubber, metals and water/wastewater may benefit from corrosive gas protection, which is now standard on Allen-Bradley PowerFlex 755TL, TR and TM drives.

These drives have been tested to one of the most severe corrosive environment test protocols that combines industry leading, 30-day exposure in mixed flow gas testing per ASTM B845 Method K with proprietary tests for industries with sources of gaseous sulfur compounds.

The PowerFlex 755T drives also now have an embedded dual ethernet port, which is capable of gigabit speeds to give users smart device insights.

Additional enhancements to the PowerFlex 755T drives include several new firmware updates for industrial control system security, maintenance resource optimization and energy usage. One of these additions is CIP Security, which helps prevent unauthorized connections and communications tampering, and provides data confidentiality. Another firmware update provides an improved software-user interface for viewing and interacting with the predictive maintenance features. In addition, frequency control modes for synchronous reluctance motors are included with several other improvements.

The PowerFlex 755T drives also now have a new option card to support TLink, a high-speed drive-to-drive fiber optic communication network. This card can be beneficial for applications that require tight coordination of torque or speed between drives. In addition to improved performance in load sharing and coordinated drive applications, TLink can also help simplify system design and commissioning. It can control synchronization between drives compared to other methods.

Users can speed time to market with the added flexibility of a configured-to-order (CTO) option for PowerFlex 755T frames 5 through 12. Packaging options include NEMA 1 and 12 type enclosures and can be ordered through the Rockwell Automation ProposalWorks tool.
