Control a conveyor belt using an inverter

In this project we describe a model to control an asynchronous motor using a frequency inverter in one of our PLCs based on Arduino.

It has been used an MDuino 42 I / Os PLUS and a frequency inverter.

An Industrial Shields Panel PC has also been used to manually monitor and control the speed of the conveyor belt and make it more intuitive.
