Need assistance with electric enclosure please (CSMIO/AC Contactor issue)

Ok well you can only have one or the other control the Contactor other wise you defeat the point of HVEnable. The point of HV is speed so no point having the Safety relay tell Controller E-stop happened then HV shut down contactor because it's actually longer.

So the Answer is you control Both directly with E-stop using two contacts on the E-stop.
One Contact controls the Master safety Relay which you then use for System Reset and any other things you want to Kill power to like, Vacuum, Coolant etc etc.
Then have the other contact control the E-stop INPUT which then Controls HV OUTPUT and Contactor which turns on Main Drives PSU.

This way you still have Safety Relay in charge of Reset system but with the faster HV in charge of the Drives power. The HV will only turn them ON when Mach is Reset. The system Reset will only turn on Safety Relay when E-stop is clear so the System will re-set and at same time E-stop Input on controller is clear so HV is safe to turn On when Mach is Reset.

Hope this makes sense.!!

Edit: If you want double safety run the HV Output wire thru the Safety relay Contact before going to Contactor. This way if Safety relay fails the PSU will lose power.
