The hydraulics on our Mori power up, but the control is dead - no lights or anything. I think it's the power supply but I'd like someone who knows about these things to check me. I don't have schematics for this part of the machine and can't seem to find any online.
What I've found so far is that when you push the ON button at the control, a contactor in the back (labelled NCM) is engaged for about 3 seconds, then kicks off.
While that's engaged, the power supply (Yaskawa CPS-15) gets 100 volts AC from two wires (marked "r" and "t", 50 volts each),
while that's happening, I checked one of the +15V outputs and got +.12V and stopped there.
Is this power supply supposed to be fed 100V, and do you think I'm barking up the right tree here?
Thanks!
