    Tips: Digital counter application in positioning control
    The paper cutter is one of the most commonly used equipment in the printing and packaging industry. The most basic action of paper cutter is to send the material to be cut to the designated location and then cut it. Using the high-speed counting function of counter in PLC positioning system and combining the multi-speed function of VFD can achieve positioning control, and using HMI can perform cutting parameter setting and some manual actions. This control system can well solve the phenomenon that the positioning inaccuracy, the cutting action is disordered, and the normal production cannot be performed, which are caused by the aging of SCM system after use for a period of time.
