    Default Re: Encoder/servo selection for a Robotool centroid retrofit

    I generally use the old transformers etc, these supplies are usually very rugged, and superior to SMPS in many cases.
    The pic's show the primary taps selection on the transformers, set for 120v
    If you have a spare contactor, it can always be used to pick up the main power or the spindle when in E-stop.

    Is it reasonable to assume the old transformer and rectifier are outputting the approximately 63 vDC required to run the drives/servos? or did the old servo amps/power board alter the voltage in any way?
