A Programmable Logic Controller (PLC) is a specialized computing system widely used to control real-time industrial processes and assemblies. The block diagram of a generic PLC is shown in Figure 1.

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...
