- Dec 1, 2008I have recieved a non-working AMC320 motor controller for repair...
I did not have that much time to look at it over the weekend, (due to the
holiday), So I just took off the covers and did a visual inspection of all
the parts and checked the fuses...
The one thing that looks a bit odd is that the microcontroller seems to be
missing its firmware... I would expect these two sockets to be populated
with a "Hi" and "Lo" EPROMs...
My E-10 is powered by two AMC320s and I have not opened up one of my
controllers (well, not that part anyway), to look if these sockets are
populated in mine.
My AMC320 controllers are probably 2 years later in design, they have a
one peice cover, which looks to be more difficult to get into.
I will open one of mine up this weekend to check it out... but in the mean
time, has anyone had there controller opened up? Did it have these sockets
populated? I would expect two windowed ceramic EPROMs, or two plastic
I also can't seem to find my RS485 to RS232 converter, so I will have to
make another one...
Thanks for any help.
Oh, all the pics taken thus far are here:
Its kind of scary when you look at the high power section... all the
current for each leg of the 3 phase drive flows thru only 8 tiny MOSFET
*wags his tail*
