Hey Everyone:
I ran through the tests in the service manual that you folks said I should
do. My transformer outputs look good. But the quiescent AC current on each
stepper was set at 10.2A instead of the 8.1 - 8.4A called for. Why so uniform?
It almost makes me think that the previous owner poured more current through
these things to make up for old weaker magnets????? Why the uniform values way
too high? I tweaked them all down into spec on the ACC board. I'm testing on
air as I write this. I'll test under load tomorrow. So Jon, thanks to you for
driving me in this direction. Now I'm nervous
I just did an index test and it seems to not be skipping a beat. But I'll be
happy if it's still working next week.
Thanks Everyone!
Andrew
