I am not always a fan of just killing the power to every thing on an e-stop.
On our high speed routers if you just kill power to the spindle, they can coast
for hours. It takes quite a while to stop from 18K rpm with out any DC
braking. So I have the e-stop triggering the external fault circuit on the
spindle inverters instead of just cutting power to them.

Hey guys,
I have been hurriedly trying to find the cash for my new components
for this retrofit. Some of you may recall that I am essential gutting this
control and starting over with all new parts and a PC running linuxcnc.
Well as of this week I am finally in a position to order the brand new
motors and drivers for the machine. I am going with all Teco units and I
am ordering them tomorrow.
I kinda wanted some specific input on getting started with the new
electronics here. My machine will run entirely on single phase input power.
I have already got the heavy gauge wiring run to the large on off contactor
in the top of the cabinet. My plan is to use the existing 24volt power
supply and a couple of the large three phase relay setups that are still in
the cabinet along with the estop button to build the basic input power
structure. I want to end up with an estop circuit that will kill power to
everything in the machine except the computer in case of an emergency. I'd
like to hear all of your thoughts on this matter and any advice on the best
method of wiring this up. The24 volt power supply in the machine can run
on either single or three phase input so that should not be a problem. I
will have lots of further questions about this build as I go along and will
be chronicling the build on my Cincinnati thread on the cnczone. Any ideas
guys? Peace
Pete
