    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.

    In this video, ATO will show you how to wire a digital counter. And how to set the basic parameters of digital counter.

    The counter does not count correctly and has a defective button
    The same issue occurs with settings of PC: 1.0 and CPS 9000. When you spin the encoder quickly, it does not count.

    The button is clearly defective and was this way out of the box. It is not OK for us to just press it quickly. Our employee will need to change the stop value many times per hour, and with the button not working as it should, it will make that task very difficult.

    1) The counter does not count correctly and has a defective button.

    2) The encoder has the wrong length cable.

    I will give you one more email to resolve both issues, and if they are not resolved I will need a prepaid return label to return the goods for refund.

    1. The counter can count at a slow speed, but it does not count correctly when it rotates fast. This problem is related to the rotational speed of the encoder, but you did not provide the maximum rotational speed data for our reference, so that this factor was ignored. Now could you please tell us how fast the encoder spins? How many revolutions does the encoder make per second? We think maybe you need to change the pulse number of the encoder to 500ppr or 1000ppr.
    2. Regarding the defects of the buttons, you can use a blade to remove the display panel, then turn on the power, directly operate the internal buttons, and check whether each button can be used normally. If the button can be used normally after removing the panel, it means that the height of the button is stuck (you can use a blade to trim and smooth the button). Please refer to the attached video.

    Please feed back the above two information first, and we can proceed to the next step after confirmation. Thanks for your understanding.
    Solved my problem completely
    This digital counter works perfectly and solved my problem completely!! It's not a fancy data logger. It has worked well, with no problems so far.

    Use of digital counter
    I am searching for a digital counter that will act with a sensor that will trace proximity from 15-20 centimeters.

    Yes, you can use our 6 digit digital counter.
    Good job!
    The 5 digit digital counter is the best choice for our automation improvement. It can improve work efficiency and reduce labor intensity. The digital counter saves a lot of time. Good job!
