Frequency converters from Invertek Drives are designed to control, regulate and protect electric motors. There are quite a few options for how to regulate the engine speed with a frequency converter, this time we will look at one of the examples.

We will use a single-phase frequency converter Optidrive E3, a 4-20 mA signal generator and a single-phase motor. The video shows how to set additional parameters so that the engine speed can be regulated with a 4-20 mA signal. The most important thing we will cover in this video is the PI control. PI control is useful for systems that need to keep the pressure within a certain range. Such as for water supply, air supply or cooling equipment.

We perform the configuration using the main panel of the frequency converter.
