Electronics for New Machine + Chinese Spindle + VFD

Actually this is getting more complicated.
It looks like if you use that 24 volt input to the VCC in on the KK01 breakout board, you need to put resistors in the output to the drivers as well.
Think your relay idea might be simpler after all.

Would proximity switches be less prone to giving false readings?
And avoid the need for the relay?
And be more accurate ?
It looks like they are powered separately from the signal line.

Here's a link to the manual that shows the switch wiring.
