WOW I didn't think I needed that much amperage to pull that single phase 7hp motor.
I obviously don't know you but you do sound extremely knowledgeable on these systems and I am really wanting to learn more on them so with that I am going to take your advise and purchase that PDS on ebay you linked me. I had purchased a Delta 3hp VFD for the UGRA I bought and now have to cancel but that is way to small and would like to stay with Delta BUT the Huanyang you linked does have a 1yr warranty and 1/3 the cost. I am a bit nervous about setting this up and I am afraid I could damage it if I don't incorporate the correct setting so I think I will give it a shot and then move back to delta once I am comfortable unless the Huanyang works great then I will stick with it
. I am far from rich but I do not want to skimp on this and have problems.
Just out of curiosity does this PDS spindle have the capabilities of an automatic tool changer or am I reading the description wrong he posted?? "the ADEV 90 series automatic tool-change spindles are equipped with a cooling fan mounted directly to the spindle shaft"
