An important consideration for optimum system control is the data a motion controller gets, and when it gets that data. In this webinar, David McNichol covesr examples of different transducer types available, as well as the different communication modes they use. There are examples of common problems with transducers and settings. Familiarity with the **Plot Manager** and the **Axis Tools** menu will be helpful for viewing this presentation.
