I've added back the safety aspect of an ESTOP event shutting down all high 
voltages.  The low voltage 24V stays on as does the PC/Monitor and the AC to 
the PMDX-126 BoB.  Ie. I have two 220VAC circuits.  One for all the Motor power 
and one for the Control power.  Only the Motor Power is removed.
 
Now click on the little orange icon to re-enable the system, ENABLE goes active 
and the AC Motor Power Relay switches  ON.
 
Interlocks prevent this while:
1.      An ESTOP is still pressed
2.      Spindle Motor Switch is in ON position, 
3.      Limit Switches are not in override if they were the cause of the ESTOP 
in the first place and are still activated.
 
The ENABLE from the PC goes through the BoB and out to the various drives.  
This happens faster than the high voltage power supplies for the drives.  
 
Is there a way to delay the ENABLE out?
 
Or will I be forced to build a circuit that makes sure the high voltages are 
within range and use the output of that to gate the ENABLE?
 
What's everyone else doing?
 
Thanks
John
