i have 4 hss86 closed loop drivers and wanting to connect the error ports on them to my ub1 mainly because i have 2 motors on my y axis and if 1 should drop out i need the system to halt so's not to twist the gantry. would i be alright in running a 5v from bob to fault+ then Fault- back to a x,input thats soldered to safety circuit? just worried that it may put too much current through bob.also looking at connecting up enable terminals on drivers which require 5v any help always appreciated.
