This is a potential issue and I cannot tell if it is just stalling out or an issue. When I am roughing out a bowl at maybe 500 - 700 RPM's, all of a sudden (mostly when I am taking a lot of wood off), the lathe shuts off. The VFD reads "ou" see the picture below. I have to unplug the lathe for a few minutes and then it starts back up with no further issues (unless I do it again). I called PM and he told me that it means that the lathe is getting too much power... so how do I fix this? does it mean that I am just stalling out the lathe?
Thanks for any help/advice/comments...
