PFTL 101A-2.0kN requirements for tension control variable frequency winding
(1) Maintain a constant tension throughout the entire winding process. The unit of tension is Newton or kilogram force.
(2) When starting the small roll, do not break the yarn due to excessive tension; Do not loosen the yarn when starting the large roll.
(3) The above situations cannot occur even in acceleration, deceleration, or stopping states.
(4) Require the quantification of tension, that is, the ability to set the magnitude of tension (in units of force) and display the actual diameter of the coil.
Advantages of PFTL 101A-2.0kN tension control variable frequency winding

(1) The tension is set on the human-machine interface, with a user-friendly operation. The unit of force is Newton.
(2) Using advanced control algorithms: recursive calculation of roll diameter; Linear increase of tension during activation of hollow coil diameter; Application of tension taper calculation formula; Dynamic adjustment of torque compensation, etc.
(3) The real-time calculation of roll diameter has very high accuracy, ensuring the smooth performance of the output torque of the winding motor. And when calculating the roll diameter, recursive operation of the roll diameter is added, so that in case of operational errors, the roll diameter can be corrected to the correct value on its own.
(4) Because the moment of inertia of the winding device is large, the diameter of the coil increases from small to large. If the operator accelerates, decelerates, stops, and reactivates, it is easy to cause yarn bursting and loosening, which will directly affect the quality of the yarn. After the transformation of variable frequency winding, the winding is stable and the tension is always constant in all the above situations. And after being processed by PLC, some dynamic adjustment measures are added in specific dynamic processes to improve the performance of winding.
