A while back I posted about maybe needing some buck xmfrs. Paul Drahn, as I posted earlier, gave me three that were the correct rating. Thanks again Paul. I connected the xmfrs and ran some tests and everything worked great. But today I ran a job which in the past would have caused the VFD to shut down due to over voltage. The spindle speed is running up to 5000 rpm and then down to 1200 in the space of .375 inches of movement at .01 per rev. So the overload meter consistently pegs at the 120% load. Not once has the machine shut down. HOORAY! Anyway, this is why I still read RCM despite all the children posting here. I post when I can help and love it when someone posts something I can use.
