My Bosch drive have the logic powered in 24v so i haven't try but it should worked has you said.
Any way i do prefer losing the position and a 30€ plywood board than a motion component €€€€
I am not in aerospatial business with a 12 axis CNC machining a bloc of Titan during 15h.

I am actually working on the electric diagram and i found a very friendly  CAO soft ( free )

The component library are complete enough for my project.

The worst example at sea  " ship fire figthing plan "

Commercial navy: they check if nobody is present in the engine room be for opening the CO2  system
Royal navy :  they open the CO2  first then,  then count the man ...... Left outside !


So, my decision is take  to let mach3 and csmio ruining  automatically  Emergency stop.
Expect for the Mushroom button and the axis over limiter which will shut down the power and make the position lost.

I believe, in case of mach3 fatal crash, the csmio E-stop output will be automatically  open ?

Good morning Hood.

Your last post give an other way of monitoring E-stop by tow stage

First stage, shut down power if : axis reach  over limiter or emergency stop button is pushed

Second stage, disable the power stage axis and fast stop the spindle if : a fault happen ( drive, thermal switch ... )

The  advantage is to be able restart the job by pressing cycle start when the problem is found


I  worked in the merchant navy, few years ago and they have the same problem.
If an  uncritical engine alarm is displaying the engine continue to run, we have a computer telling us what up. during the night  it give us the phone number of  cabin mechanic man.

But if  oil vapor is detected in the dry crankcase  :'(.  The engine is automatically stop by the computer !!!!! Before it explode  >:D
And if you are by night in the storm with the alternator coupled to this engine, you loose all the electrical power and propulsion !!!!!
But you  are not burning in hell, just adrift.....


So which way is the best about CSMIO. One stage or tow Stage E-stop ?

Yes it is the csmio/ip E-stop input

So my POWER ON push button will have 3 effect

Bypass the safety loop
Bypass mach3 drive enable
Powered the PNOZ safety relay solenoid

After 3 second if all the motion equipment  are working correctly the safety loop is self-maintening and you can release the POWER ON

It is a kind of STARTER !   I should call it   " IGNITION "

So, i am in the good  "Industrial" way

The point is i don't TRUST in  Windows computer for my safety.  I prefer coil and mechanic.....

A question about MACH ? It is possible to reset an emergency fault in mach3 ( axis not ready ) until i powered them up ? it is because a need a close contact drive enable.
if not, i will put a by pass to shunt Mach3 during the launching phase.

Picture of my RYE CNC router

When the truck delivery me the machine the way was FROZEN so i get the help of the neighbour with a crane... pulling the truck !!!
that was the beginning of a long day,

So before i start  drawing  the  all wiring system diagram , i would like to have   opinion of  mach3 users  about the  Machine Start up procedure



Switch on procedure

1. Switch mains isolator ON. The transformers 24V  110V  220V  are powered.

2. Push the green button "SYSTEM ON".

   2.1  The Mach3 computer will boot up.
   2.2  The system  contactor get closed.
   2.3  The CSMIO controller and the SAFETY closed-loop is powered in 24V
   2.4  The Bosch servo drive are powered in 24V
   2.5  Emergency stop is activated because of the drive 380v main power is missing  K01

3. The Mach3 control display  shows "DRIVE FAULT" and "E-STOP"
    
    4    Reset the fault in Mach3 to activated the drive ( drive enable )
    4.1 Push " DRIVE ON "  button for 5 seconds until  K01 stay closed  ( drive enable signal got trough the  K01 380v NO contact  )
    4.2  this action will bypass  E-STOP loop by powering directly the  Safety relay  ( PNOZ-X3 )
    4.3  this will closed K01 and enable drive power stage 
    4.4 the drive ready signal ( drive fault ) is now close in the safety loop emergency circuit 

5. Machine is ready for automatic  HOME POSITION

---------------------------------------------------------------------------------------------------------

DRIVE ON  will be use after an  EXTREM OVER TRAVEL , in this case turn the switch OVERRIDE ON  and Hold down the button until you cleared the switch by jog the axis in the opposite way

If the machine reach an Axis limit switch, turn the switch OVERRIDE ON  ( this will bypass the open limit switch by delivering 24v signal to the controller input )

Good news, next week money should come in and i will order the controller.

I have done the IN/OUT  load specifications and  i will have enough IO  with the main SCMIO/IP-A  controller.

here the links of my need and how they will be plug to the board.

For people like me having  their  brain smoking by retrofiting an industrial CNC machine

You can watch this video, solving a  problem could be worst than a cnc ..... http://biertijd.com/mediaplayer/?itemid=40360
