Q : What is the purpose of frequency swing of VFD in textile industry?
A: It is mainly used to prevent silk folding. When the winding diameter is at a specific value, the trajectory of the first repeated action will achieve the effect of coincidence. Too many yarns overlap to form silk folding, which brings hidden dangers to the unwinding of the next process. Therefore, it is necessary to add swing frequency, which is equivalent to adding appropriate disturbance in the regular operation process.
