Control loop
Each control automation is based on a simple control loop. Even complicated tasks may be reduced to such a control loop.
Fabric position
Starting point is the actual fabric position.
Sensors
A sensor detects the actual value of the fabric either mechanically or without physical contact.
Position controller
The position controller compares the actual fabric value with the set target value and sends an appropriate correction signal to the actuator.
Actuators
The actuator corrects the fabric run.
