Hi All.

I have started to put my CNC router control circuit together, and I am concerned where in the circuit I should place an E Stop.
I have noticed the my PSU (240 vac > 36 vdc) transformer, on the 36 volt side stays powered for a few seconds, my initial thought was to place the E Stop in the 240 vac line to the PSU, If I am right this will not stop the motors dead will it due to the fact that there are Capacitors on the 36 volt rails keeping them live for a few seconds, or have I got it all wrong.

Regards.

Ray
