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.

Thanks, Eric.
glad they are working for you.

I'm less than totally on topic.
But, here is a chance for me to
say good job, and glad it's
working for you.

stuff to do)

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
