Company and Product News

Rockwell Automation has released new enhancements to its Allen-Bradley PowerFlex 755TL, TR and TM AC drives, including new standard corrosive gas protection that is often critical in industries, such as pulp and paper, automotive, tire and rubber, metals and water/wastewater.  These new enhanced AC drives have been designed to withstand severe corrosive environment test protocols that combine 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 AC drives also now have an embedded dual ethernet port that is capable of gigabit speeds to provide users with additional smart device insights.

Additional enhancements to the PowerFlex 755T AC 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 to prevent unauthorized connections and communications tampering, and provides greater 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 enhanced PowerFlex 755T AC drives also 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 to simplify system design and commissioning. It can control synchronization between drives compared to other methods.

Users can help to 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.
