The PFSA 147A  control principle is shown in Figure 6. The length that needs to be cut can be converted into the number of pulses. When starting, Y1 has no output, that is, the servo is driven by pulses from the Y0 contact of the PLC. At this time, the rolling cutter quickly runs to position A in the diagram. At this time, the difference between the high-speed counting value of the PLC and the number of pulses converted to a fixed length is very small. Assuming the rolling cutter receives 10000 pulses and rotates once. After the fixed length conversion, the number of pulses is 5000. When starting, the PLC sends pulses to quickly make the rolling cutter run 9000 pulses and stop at position A for waiting. When the high-speed count reaches 4000, the interrupt is turned on to output Y1. At this time, the servo is driven by the encoder, and the remaining 1000 pulses are driven by the same frequency to complete 1000 pulses, achieving the effect of synchronous cutting. For example, application areas such as dyeing and sizing machines, multi unit yarn sizing machines, etc.

PFSA 147A  and tension control are classic transmission automation problems that have a wide range of engineering applications in the production and manufacturing of multi frame continuous materials such as textiles, printing and dyeing, papermaking, printing, and wire. Since entering the era of variable frequency drive, the combination of PLC synchronization and tension PFSA 147A  control system has become a cutting-edge integration hotspot in electrical drive automation engineering. The high-performance synchronous and tension transmission control system is driving technological progress in many industries. This article combines the technical characteristics of the Delta electromechanical platform and systematically discusses the solutions and engineering achievements provided by the application of new technologies for traditional transmission automation, which has profound technical promotion value
