Greolt - thanks for that info about the simple cooling system. Mine is being a pain. So I just ripped it all apart, got a 5 gal bucket, put the submersible pump into the bottom and I am off the races! The pump is 300GPH, so I put a bleeder valve on the line right in the bucket. Keeps the pressure down and the pump from working too hard.
I love simplicity.
jeffrey001 - yeah the VFD was a little intimidating at first, but it turned out that google was a great friend. I'd just search for things like "CNC PD003" and up came a few different forums. There are two manuals floating around out there, I have attached a zip version of the better translation.
Also I forgot to post the connectors:
E to ground
R (L) input power to 220V hot
S input power to 220V hot
T (N) input power (for 3 phase) unused
U to motor pin 1
V to motor pin 2
W to motor pin 3
P1 Not used.
P+ Not used.
PR Not used. Braking resistor
