The advantages of controlling the movement of a machine or conveyor by a frequency inverter, range from efficiency in energy consumption, to the speed and rotation control, allowing to the operator more control in the final application of the machine.

​

Through a Profibus communication, the PLC can monitor and control a row of frequency inverters in the same network, orchestrating different sections of the production to meet a predetermined objective.

​

For this application a Danfoss frequency inverter is connected to an S7-300 PLC through a Profibus network.
