Pepperl+Fuchs Podcasts

Pepperl+Fuchs’ TechTalk helps listeners gain an insight into modern automation technologies by focusing on AS-Interface (Actuator Sensor Interface) and its associated safety technology, Safety at Work. TechTalk covers topics that range from hardware selection to installation and maintenance. Control engineers familiar with AS-Interface will get the latest news on specification enhancements, hear about new products, and familiarize themselves with established and cutting-edge troubleshooting methods, tips, and tricks.  Users who are interested in applying these technologies will learn what it takes to set up an AS-Interface system, how Safety at Work improves safety systems, and why those technologies have the potential to save time and money during all phases of a project.

Hardware -- The safety speed monitor evaluates data from the safe-rated encoder. In a nutshell, the safety speed monitor evaluates the sine/cosine signals from the encoder, and determines if the speed is within limits and if the direction of rotation is what it should be.

  • --The safe-rated encoder is built up redundantly with self-monitoring electronics and is third-party approved (TUV)
  • --The safety speed monitor determines if the motion is outside the limits set by the user.  A safe-rated signal is then sent to an AS-Interface safety controller
  • --The speed monitor can be used as part of an AS-Interface setup or as a stand-alone device
