 Operation Overview
A bobbin winder on a spinning machine will be used for in the following example. 
The rotation speed of the bobbin winder must be made variable as the thread is 
wound, so that the speed at which the thread is pulled stays constant. 
The target speed is achieved based on input from multiple contacts. Acceleration 
and deceleration is modified by the acceleration and deceleration of an inverter. 
 System Configuration 
CP1L and CIMR-V7 (an OMRON inverter) are connected by RS485 for frequency 
and start/stop control.
