Spindle Stop?

[Ricardoco]

In your block diagram, the stepper motors get their power from LV Supply (via the stepper drivers)....in turn the LV Supply gets its power from the HV supply (mains?) ...therefore if HV supply blows a fuse, LV supply won't get any power...therefore the steppers...they no workee.

Yep thats the idea, and the spindle stops too!! Blown fuse system stops..

In case I wasn't clear, what I meant is, as its drawn Ray needn't worry about his steppers continuing to turn if mains blows a fuse.

Cheers Hank, i knew what you meant, but the problem is i dont know what he has already, it may be the system is all build and thats where the problems will come in, although i would just shove in a latching mains contactor and run the HV stuff out of that, quick fix i know, but worth while and easy.

Hi Guys

Thanks for your contribution so far, but i think there is still some misunderstanding, to answer a previous question, my Mill is powered from a Standard 13 amp 3 pin outlet. I have enclosed my BLOCK diagram of what is actually the condition of my system now, I have 3 different 3 pin 240 vac supplies, all with there own 10 amp fuse, if Mill blows fuse due to overload condition, cabinet and PC are still Powered.

Hi Rick

That looks great many thanks, IYHO what would be the best way to divide the 240 supply, my thoughts are a 240 volt busbar in the cabinet, with a tap off to the Mill and a tap off to the rest of the cabinet.

As jazz has pointed out using a relay (with the correct rating)is really the best way, but if not then have their own fuses. But the first is preferred as there is a higher degree of control when using a relay. Rick
