The coolant pump that is in the machine now is a three phase unit but Eisen was kind enough to throw in a single phase pump that is in a box. I may be way off but I thought the single phase power would go to the vfds R/L1 and S/L2 and the Motor would get it s three phase power from the U/T1 V/T2 and W/T3 terminals and get your forward reverse from the control circuits from one of s1 to s7 and set your brake parameter to coast to stop and receive it s signal from the control circuits from the lathe wire d to the control circuits on the vfd. Hmm I totally respect what you say. I am in the dark at times here. I Start to feel better about it and then realize how far off I am. I Need to absorb what you have stated and relate it with the manual and the lathes manual I have to move the lathe to get a good picture but I will and the schematics as well. It may be on the wkend as I am at crunch time at work and wont be home at a decent time and may have to work the wkend. I Would be crazy not to. I read what you said and responded without really going through it properly to understand it. I appreciate everything
I am going to auto tune though. I Think it is worth it and like you said it will be smoother and isnt that what we are after. I probably won t use the coolant pump all that much but when it s needed it really does help and this is a bit more than a hobby for me, maybe a mid life crisis and will definetly have an electrician there with me.
