You have to consider with your industrial experience there systems are not turning off these high speed spindles and are also operating with 3Ph power and most machine would have a Breaking
So Estops for this type of install have to be configured so the main supply power is not remove until the spindle has stopped

So enough of what the industrial builds require, and show a better solution for a Single Phase Build that have more hurdles than any industrial system to over come, they don't compare to a Single Phase Hobby Build

That is exactly what I posted, it is a very simple way to conform to safety requirements and also cause no stress or damage to the VFD.
If the OP needs it, I can post an example schematic.
Every system, whether amateur or professional should have a legitimate E-stop circuit.

Implementing it is another thing everyone should be using a Safety Relay in the Estop circuit this is the best way to do it, the biggest problem is to get the motor stopped before the mains disconnect which is not so easy with some of these cheap VFD Drives
