Rockwell Automation Envi AC Drive Option Module Integrates Safety Functions

AC drive applications that require safety functionality can now benefit from the integration of safety and standard control systems on a single network using one controller. The Envi from Rockwell Automation offers several safety functions based on IEC 61800-5-2 standards for Allen-Bradley PowerFlex 755 and 755T AC drives. It includes the ability to monitor speed, direction and position on an EtherNet/IP network.

Networked safety solutions minimize hardware and installation costs by simplifying machine design and reducing equipment redundancies. With fewer components, manufacturers can reduce the size of panel enclosures and save valuable floor space. Networked safety solutions also provide zone control in which one machine zone is brought to a safe state while other zones continue to operate. In the past, a safety event in one section of a machine could result in the entire machine shutting down. Integrated safety allows the control and safety systems to coexist on the same network and share data between the safety and standard applications.

As part of a comprehensive offering, a single Allen-Bradley GuardLogix controller can manage safety and standard control in one software environment, Studio 5000 Logix Designer. With no need to write and coordinate multiple programs on different controllers, manufacturers can simplify the programming process and save on training and support costs.

The integrated safety functions option module provides ratings up to and including SIL CL 3 and PLe Cat 4, when used as part of an integrated safety system that includes a GuardLogix 5580ES controller or Compact GuardLogix 5380ES controller. The option module can be added to the drive at any time.
