Kabibble, no offense intended at all- you gave sound advice with the limited info you had, and I'm grateful. So, I have the C6 board. Does it have similar dedicated E stop port? That would be perfect.
If it doesn't, can I put the Estop in series with the Spindle on wire and shut the spindle off that way? I guess I'm imagining the Estop breaking the circuit to ground, and thereby triggering the relay in the VFD to shut off the spindle.
Can I also take the 'output' of the Estop switch to the limit switch input on my Ascension controller? Right now, if any of the limit switches are closed the controller shuts down the steppers instantly. I think its doing this thru the Mach3 software, but I'm not sure. If I put the Estop switch in series with this as well, it should trigger a stop just like the limit switches do.
If I do this, wire both circuits to the same Estop switch, will I have interfernce from one circuit to the other- i.e will the operation of VFD relay be affected by the presence of the limit switches and their cabling?
It must be obvious to all that I'm no electrical engineer. I appreciate your help to get me to understand this.
