    Re: MX4660 Speed Control for 2.2 KW huanyang vfd

    The MX4660 schematic is not released, there is a channel to output analog signal to control VFD. Refer to page19 http://www.leadshine.com/UploadFile/...4660d_V1.2.pdf
    PIN14 for PWM on DB25, PWM pulse input. Used to get the PWM signal from the controller which will bethen transformed into an analog signal to an external device connected at“0-10V out” pin of the analog output connector (CN8 on Figure 3), such as aVFD for spindle speed control.
