From the nameplate data, it appears that you will need ~50V Dc (3*16.5) and for a 4 axis machine, I would rate the current flow at ~(4*10*.66) or 26 Amps based on previous discussions that I have read here and elsewhere. Also, I see this unit has a tachometer and you will need an encoder to work with the Gecko. If you add an encoder, try to find one that uses <50ma current supply @5V or you will have to have a separate power supply for that. The AMT encoders seem to be in favor at the present time for the Geckos and can be found at DigiKey.
Hope this helps.
