That is the same one I recommended to another 1440GT owner the other days, either great minds think alike or we are both getting senile and are looking at the same thing. Good to know. I am going to but together some schematics that use the basic contactors, but will have a few more extended control features if one wants to step it up. You can get a very nice install for minimal investment and get some very nice control features. The other option to keep the costs down is to mount the VFD in the headstock cabinet on some L brackets, and swing out the side panel for access. Thanks JBOLT.
