Multiple limits and homing
« on: June 20, 2013, 09:12:54 PM »
Can I share multible home switches on one input.  Right now I use one prox with 2 flags one for + and - limit/home switches and it homes fine.  But I am out of inputs and want to add some things without going to modbus or something like that.  So can I use one input for mulitble axis?  I know it will work electrically but will it work in mach or will I get a limit trip when homing?
Thanks,
Don

Yes, you can wire all of your home switches and limits switches to one input if you want.  The reason it can still home correctly is because Mach follows a routine when homing.  It isn't looking for a particular switch, it is looking for a change of state and they can all be on the same input.  If anyone of them trips while not homing it will throw a limit switch fault.

Thanks that was what I was hoping for.  I knew mach disreguarded the limits while homing just didn't know if it was all  limits during the whole homing process or an axis by axis basis.
