Should input 10 be GREEN WITHOUT power applied to input 10 on the GPIO4D board and turn RED when power IS applied?
That is the case at this point. all other inputs turn green when power is connected and red when
power is removed. Not sure why input 10 is opposite.

The PLC program can invert the state of an input, so that a closed input appears open and vice versa.

The basic GPIO4D PLC program assumes that INP10 is the spindle drive fault input. The PLC program looks at bit 1 (value 2) of Machine Parameter 178 to decide whether to invert INP10, in order to support a spindle drive with a normally-open fault signal.

It sounds like you have that bit set in Parameter 178.

Ok, I got past the faults. The problem was the stop is input 11 and not input 8 as shown in the drawing.
I am now able to set home position. now the Z + and - keys move the axis in the proper direction, but pressing the X + and - aslo move the Z axis in the negitive direction!
Also running the auto tune, the Z axis move slowly but makes a severe buzzing/viberation noise. Should I let it continue with the noise?

Did Z move smoothly before you ran Autotune?

What type of servo drives, motors, and position feedback are you using?

Is it possible that Autotune shook your encoder loose?
