I'm going to be hooking up my 1990 Mori Seiki AL2 soon, but I have concerns about the input voltages.
On the inside of the cabinet it says "input voltage - 550v/60hz" .. hmm, ok... I have 220 3phase, so a 600volt step up transformer would do the trick using the correct tap.
Now, upon further inspection I noticed that there is a small 3.5kva transformer inside the cabinet. It has a couple labels on it with different connections and taps for various input voltages from 220 volts to 550volts.
So that makes me think, hmmm... maybe I don't need an external transformer... but being that the internal one is only 3.5kva, I can only assume that it's just for the control... maybe also for the axis motors but who knows.
Anyone know more about this than me? Do I need a transformer or not?
Another confusing thing about that internal transformer is that it says something like "wire V" listed under input voltage of 220 volts, it says "8-15". Well there are terminals 1 to 20 on the thing... would I move the V wire to 8, 9, 10? I'm pulling those numbers out of my head - I didn't write down exactly what it said, but that's the gist of it.
Wish I had a manual. Thanks guys.
