Al, THANK YOU for the help.
Can you explain these comments made by HuFlungDung in a post from 2007 that you participated in?
I have a feeling he is saying that the 24V DC supply provided by the Hitachi X200 should be used for the estop circuit. But if that is the case why am I putting a contactor where I'm not supposed to. I'm sure I'm just not understanding.
And in case anyone else is reading. In another thread Al posted a link to this website: All About Circuits : Free Electric Circuits Textbooks It has been very helpful for me.
So here are the comments that I am asking about.
You'll want to use the VFD to create the spindle motor control system.
Estop and on, off, reverse must be handled within the VFD as you must not break the main power between the motor and the VFD output.
