"And the correct EMI Power Filter I recommend does a better job than this line reactor
Posting information from the likes of Yaskawa or from any Drive manufacture, you first have to have an understanding of the subject and have experience with this, before you post something you know nothing about"
You were discussing Power correction factor with some of the usual suspects. What came up was that Vfd's were very inefficient and had to be severely derrated. Some saying down to 60% or so and that possibly a reactor or your recomended TDK filter could boost that up somewhat.
with respect to chinese spindle grounding, I had continuity between the #4 pin and the spindle case. I grounded pin 4 to the VFD anyhow, for good measure.
Sidebar: How does that work with ceramic balls in the bearings resulting in no path to ground?? unless there is some kind of grounding brush or whatever.
Did I clear anything up or add to the confusion....lol
