Hi

I0.7 Homing not working axis stop

Stupid question maybe from me.

What drive are you using?  With V90's there is negative logic to comply with the shitty Japanese drives that they try to copy.

The home switch may be better off being an NPN, not PNP switch, which also means that the inputs for your S71200 need to be switched. 

Switch your L+ and M- to the opposite (trust me on this, M = +, L+ = -). 

I ran into this exact problem.

OK, so let's back up a few steps.  What is the problem you are trying to solve?

You can't read the home switch.  that is a hardware problem.  Check your wiring, check your device.  I use this with V90's all the time and it works fine.
