    Randtronics TU-500-10

    I'm looking for manual or schematic, or even advice or knowledge on the connection diagrams for the TU-500-10 DC controller. It is 230V 3Phase drive, converting to variable DC 10HP motor. Circa 1980.

    It is on an older NC lathe to run the spindle, am trying to figure out what the connection points do so can convert it to pushbutton or relay control from the old 1980 tape controller.

    Thanks!
