  1. The bigger question is WHY? What benefit will you get adding rs232/485 capability? Seems a lot of work for little return plus the internal software of the VFD may not be configured to use it.

    No its not big work because i have PS/2 connector & spare smd parts
    i have ordered 10pcs from each ICs (max232 & SP485) from ebay and i have allready found the most parts values.
    The manufacturer price for this operation is only 50 cny ( 6 euros )
    ڹܲ-Ա so i will try to pay him to give me the values of components.
    The driver supports rs232/485 with extra 6 euro.
    I found manufacturer(perhaps wholesale seller) webpage: cnyfdz.com

    Also i have tested the driver with the connection phase -> L1-L2 bridged , neutral -> L3 and works fine with using 2 rectifiers (8 of 8 diodes in the 2 rectifiers).
    So this is the proper way to connect this drive in single phase 230VAC next is to measure DC bus for ripple on big electrolytic caps (with default 3 caps)

    I want to connect these servos with pc (mach3) and because for first time iam using servos i need some help how to connect them with pc parallel port.

    Here is the manual of this drive version 3 (in version 2 a lot of things are wrong/missing)
