152 SYSMAC CP1L/CP1E Introduction Manual
■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 V1000 (an OMRON inverter) are connected by RS485 for frequency and
start/stop control.
