| Abstract: | In order to ensure high-speed warp knitting machine sent constantly in the high-speed cases, the advantages of modern electronic let-off system were explored after analyzing the defects of traditional mechanical let-off system, Omron CP1 H programmable logic controller（PLC） was used as a core control unit, a kind of electronic let-off control system based on the PLC built-in PtD control was designed. The stable let-off in high-speed warp knitting machine was realized. The results that this system run on YJKS3 high-speed warp knitting machine, show that the system is stable and reliable, response fast, and has constant warp tension, improves the fabric quality and work efficiency. |
