Good morning all,
So I have finally acquired this machine from my uncle's shop. It's sat for 7 years, however, worked flawless when it was last operated. Verified that as I was there when it was operating last. It's been sitting collecting dust otherwise. So after disassembling the head to get it to clear my garage door at home, we loaded it up and brought it home. Once back together, I connected it up to the 3 phase inverter that American Rotary said would be NO problem. This phase inverter came with the lathe I purchased a month or so prior and works fantastic for the lathe. New to those inverters, so, when he said i could connect it up, I thought AWESOME!! so yeah.. it's not very awesome.. I hooked it up, powered the machine on and it booted fine to the main screen with several corruption errors and a drive fault. I pushed the drive enable button and heard the relays click, but no other responses.. pressing enter to home, pressing execute, etc resulted in no action except the drive fault still being there. Pressing acknowledge button just turned off the drive relays. Upon opening the control box door, a nice little plume of smoke came out... Going thru the voltage checks, it appears I'm getting 139vdc to the controller boards and 31v where there should be 24v. Now strangely, all the status LED's show perfectly normal. I can watch them go thru their tests, etc.. I have discovered that on a 3 phase converter, one leg will be high voltage.. In my case, it ranges from 260-270 volts. I have since changed the wiring to send that high leg strictly tot he spindle motor. and keep the control power supplies off that wild side. What are your thoughts on having possibly fried the board, or just the transformer got too hot and smoked? I would say the drive relays were closed for maybe 15 seconds tops... not sure what these boards will actually take. I have a lead on a full set of drive control boards for a decent price and they are known good boards. I just do not want to have to buy them if I;m overlooking something simple.
my other question is the air supply. can I run this machine without air temporarily? I need to trace down an air leak and I have a very inadequate small compressor that can't keep up the 75 psi that the book calls for.
Please let me know if you need more information. Looking forward to getting into production. Retrofit will be down the road as soon as funds allow. Thank you in advance for any information, insight, etc to help get this machine back going again.
