Most VFD have an internal relay you can program to trip when the VFD gets any error. You would connect the contacts of the relay into your estop switch, you could wire the relay nc contact and an error would open estop circuit.

I will try that !
I just checked the ground pin #4 in the spindle plug and it's not grounded to the spindle body ... Should I open the spindle and wire the ground pin to the spindle body ?!
Thank you guys, I truly appreciate your help .

Yes the 4th pin needs to be Grounded, there is more than one way to do this, but most do it like this, make sure you blow the water out of the spindle before you take the top off, and make sure the 2 orings are sealing when you put it back together

Your parameters can't be set correct, as you should not be able to run the spindle below 6,000RPM
