Tension control is important when you want to enhance machine runability and product quality. But you will find that it is executed poorly in most cases because of poor engineering. This means that controllers are often tuned to incorrect or distorted signals that can result in poor quality products. This is why you use tension control. Most tension controls systems are designed to work with a very small margin of change, no more than 1%. The tension control is used to enhance web handling, especially when machines are handling speed changes. They are also used to compensate for directional variations. Notably, tension control is generally slower compared to speed control. To be precise, it is about ten times slower that standard speed controls. Your system needs good tension controls for higher efficiency. However, when your machine is carefully tuned, the sensors
become are mainly passive. Therefore, do not risk; have the right tension control installed when running your system.
