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
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 ?
