My broadband went down early in the week so i decided to get the cable runs organised. i also fitted the home/ limit switches. i had gathered switches down the years so i decided to use them istead of sensors . Clive posted a link some posts back to some sensors that i will use if these don't work out. i also cut an opening in the door for a small window on hinges so i can see the VFD and adjust accordingly. i'm still a bit unsure about the inputs to the BOB ( which i plan to tackle next) i have a dwg. organised relating to the E/ STOP input to the BOB which i hope some will have alook at and give me the thumbs up or down.
my query related to if i have the e/stop connected to the BOB correctly . is it o.k to take a tap after the e/stop as per dwg and use this as an input? this terminal disables the enable to the drives . i'm still trying to get my head around the fact that i can hook a supply and a ground to the terminals provided without having a dead short and blowing the BOB .
