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.
Speed
Contact A
The target speed is changed according to inputs from multiple contacts. Acceleration and deceleration
are controlled using the acceleration and deceleration of an inverter.

The CP1E and OMRON 3G3MV Inverter are connected using RS-485 for frequency and start/stop con-
trol.
