Safety Functions Documents

Safety Functions Documents

E-stop, guarding, or presence sensing function are machine safety functions that require multiple elements. The elements include a sensor or input device, a logic device, and an output device. We provide guidance for specific safety functions that are based on functional requirement, equipment selection, and Performance Level requirement.

Built with you in mind, these safety functions minimize risk and speed development. Examples of the information that is provided in our safety functions documents include:

  • Set-up and wiring
  • Bill of materials
  • Wiring schemes
  • Configuration
  • Verification and validation plan
  • Calculation of Performance Level

Stop Category 0 or 1 Using Programmable Controller and Kinetix Drive with Integrated Safe Torque Off on EtherNet/IP Networks

This document explains how to use a GuardLogix® controller and configure the Kinetix® drive with integrated safe torque off subsystems of a safety function. The GuardLogix controller de-energizes the final control devices. The final control element is de-energized immediately for a stop category 0, and a delay is introduced before de-energizing for a stop category 1.

Stop Category 0 via Kinetix 5000 Servo Drives with Hardwired Safe Torque Off

This safety function explains how to combine a Guardmaster® dual-input safety relay and the actuator subsystems of a safety function. In this application technique, the Guardmaster dual-input safety relay de-energizes the final control device - in this case, the hard-wired safe torque off inputs on the Kinetix 5500 or Kinetix 5700 servo drive. The final control element is de-energized immediately for a stop category 0.
