Available Safety Options

  • Safe Torque Off option is available as a networked or hardwired solution, both certified at SIL 3, PLe, Cat 3. This option removes rotational power to the motor without removing power from the drive for faster start-up after a demand on the safety system.
  • Safe Speed Monitor option is certified at SIL 3, PLe, Cat 4 option allows you to safely monitor and control the speed of your application. This allows operators to perform some process or maintenance work without stopping the machine.

Networked Safe Torque Off Option Module

A new safety option card provides Safe Torque Off (STO) functionality via a built-in EtherNet/IP port for the PowerFlex® 755, PowerFlex 755TL, PowerFlex 755TR, and PowerFlex 755TM drives. The ability to integrate the safety functions over EtherNet/IP provides the opportunity to reduce hardware and installation costs and improve productivity. The STO option module offers a SIL3, PLe, CAT 3 rating to help reduce wiring and panel footprint.

For flexibility and simplified machine design changes, the option module can be used for both hardwired and networked STO applications.

  • Provides networked STO over Ethernet/IP
  • Supports both safety via EtherNet/IP or hardwired which is ideal for customers that want future network functionality
  • Approved for networked and hardwired STO (TÜV Rheinland)
  • Offers SIL3 / PLe, CAT 3 rating
  • Requires PowerFlex 755 drive firmware v13 or higher, PowerFlex 755T drive firmware v1 or higher
  • Requires ControlLogix® or CompactLogix™ GuardLogix® controllers and Studio 5000 Logix Designer® software V30
  • Functions in ports 4-6
