I am going to run 3 320 servo drives with servos that have a max current of 30a so I want to be able to use the full 20a that the 320's provide I also want to run the most voltage I can the servos were rated for 90vdc. the 320's are rated for 80vdc. Will it be safe to run a ps that produces 79-81 vdc no load current. I know the voltage will drop when there is a load but will the voltage be to high when the servos are'nt running? My next question is should I run a sepperate ps for each drive or one ps. If I run one ps would I be ok with one that produces 30-40a. I doubt that the servos will ever all be at max rated current (20a) at once. Most likely only one will ever be at max at one time.
