Hello TechTeam, Thanks for you answer. I guess I will use the unwinder as a speed master and the winder as a tension control. See attached file. The trash coil can be used for unwinding 1-3 aluminium coils. No we don't have any speed measurements. The operator will give a speed reference and be able to tune the speed with a potentiometer. We want the "unwinder" to rotate quite slowly, approx. 10rev/min, so that means that the material will have a velocity of about 50-55 meters/min depending on diameter of the coil. Do you think the tension control in the winder works if we use the reference signal from the operator, e.g. 55met/min, and the velocity may differ around 5meters/min. The material that shall be unwinded can also differ in quality and thickness can differ between 0,2-1,2mm between different coils. Is that crucial for the application?
