Before digital control systems, responses were fairly slow. Push a button, and a motor contactor engaged. These days, the speed of computers introduces some new challenges but brings solutions as well. In the control system engineering space, it is well known that two different techniques exist for switching purposes, those that are purely mechanical and … Read more
This article discusses the importance of rev counters when troubleshooting a robot and how to update rev counters as needed. What are Rev counters? Rev counters are the servo motor encoders on the axis motors of a robot. Although the term Rev counter is considered an ABB term, all robots use encoders on their servo motors, … Read more
Whether using an industrial DIN-rail power supply or a linear supply for an audio application, these devices have the potential to fail. Although there can be several reasons, there are a few simple (and some not-so-simple) methods of testing a power supply for proper functionality. Locating the faults in a system so often seem to … Read more
When troubleshooting AC outputs driven by TRIACs, some confusing meter readings can result from the solid state properties of a series circuit. In this article, learn proper troubleshooting techniques. In most discrete PLC systems, the process of troubleshooting output devices is quite simple. If the output terminal is working, then you should measure 0 volts … Read more
