Yes, I know that.
Thanks.

I think your tool changer should take an enable input, which should be
tied to your machine's estop chain.
I think so too, but I can also agree with Marius that you wouldn't
expect a machine that can't run Auto (yet) to set

I don't think it's a bug. Do you?
What mode do you think it should start up in?

I dont really know that is why I asked what the thinking of others were.
My opinion is that the machine should always start up in the manual
mode. The reason I discovered this is that I wrote a Automatic Tool
changer component for a Hurco mill. I looked for a exclusive condition
of Auto mode

Grounding is really important. Noise on logical ground usually cause
communication errors and could of course trigger a limit swith, have you tried
lower input impedance?
A common mode filter on the output may be a good idea.
I have the theoretical knowledge but limited experience.

The inverter output voltage have very fast flanks to get low switching losses
and the circuit is closed by the capacitance in motor to protective earth.
There are usually also a capacitance between internal transistors and cooling
fin connected to protective earth. The capacitances
Adding one more note -- I've been testing/verifying with a dial
indicator mounted to the machine, so I know I had a major issue before
and I know it's resolved now.
