Ok It would be nice not to do a full retrofit.
There is a dual stacked servo amp with one breaker on it 250V 15A. I don't know if that is for both amps or just one. They are intergrated into one unit. IT controlls both big 5f servo motors.
The next servo amp is smaller and has 3 removalble fuses at 250V 5A
The last two servo amps are the same size and part number 3 fuses at 250V 3A.
Break down of input to transformer #1 of 3. 480Vac 3 phase Line in to knife switch. Switch to 3 20amp fuses. to contactor, branch goes to power input module and other branch goes to 5kva transformer 30amp fuses out. There are 2 other transformers down the line a 1.1kva f1 20amp f2 10amp and a 1kva f1 10amp. I'll attach a couple marked up pics on what i got. I don't have a manual. They want $150 for them and if i have to tear it all apart then the manuals won't do me any good. If i can get power to it then i will get the manuals in the future.
I guess the reason they say use such a big rotary phase convertor is to double it for stability. Like i said 3 phase is all new to me.
I have a 25hp 3 phase motor laying around i could make a rotary phase converter out of if i knew what i was doing. And if it was the right size.
Thanks again
