Hey guys, I'm involved in a 5 axis cnc router build and we're working on electronics now while we wait for parts. We need some major help with something that in theory should be simple, but until you do it...
We're using the pmdx series of breakout boards,
and we're using geckodrive stepper drivers powered by a 56vDC psu (110vAC)
and a 220v 3phase spindle
I've been looking at this drawing all day(the normally closed Estop one), from what understand the estop and relay on the board engage the contactor which cuts power to the stepper motor psu.
But in our case how would we integrate a 220v 3phase contactor into this schematic? Whats the safest way to do this? Using another relay or could both contactors be run together? Do we need two contactors?
I've been researching all day but I'm missing something, I would really appreciate any help or even a quick schematic to look at would be great!
