Hi all,
i have a mori seiki MV40 with fanuc 16 series controller, which have been problematic ever since i had it.
Awhile ago, it starts up really slowly, meaning i need to wait around 30 mins before the CRT display turns on. Then on one fine day, it doesn't start up anymore, then i had someone to come to fix the problem, it turns out to be a problem at the I/O section.
now that the starting up problem have been solved, the parameters have been re-entered, i now have this alarm showing up every time the code M5 is run.
sometimes it shows as:
- 751 spindle alarm (AL-30) or
- EX451 spindle unit alarm.
my question is, do they mean the same thing?
and if the problem is of AL-30(which is a overcurrent in input circuit), in the maintenance manual, it says to remove cause and reset, but i have no clue on where to remove the problem or where to start searching for the problem.
i'm sorry if the information i give is too little, and if i sound too noobish, i've tried searching from google and found little information.
thx for any kind of help.
