A bobbin winder on a spinning machine will be used in the following example.
The speed of the bobbin winder must be controlled as the thread is wound because the speed of the
thread is constant.
The start/stop and target speed is changed according to inputs from multiple contacts. Acceleration and
deceleration are controlled using the acceleration and deceleration of an inverter.
