One was behind the spindle on the clamp withwithout tool detection wires, the other was under the Z axis way covers at the terminal box. Just to follow up on this in case someone else stumbles upon it, the problems with both machines ended up being shorts in the 24VDC system. We do, however, have a large voltage drop when the NC power is turned on which is causing some components to not turn on.ĭoes anyone have any clues on where to start digging to find the source of power draw or known faulty components Thanks in advance. We have been having the same issue at our shop on two mori seiki SH-400 machines.
Ive been reading this thread for a while hoping to get some inspiration. Im having the same issue but Fanuc and Mori dont know what to suggest. All world machinery 200, Mori 300 for a new one. I am going to run a warm up program for a couple hours to see if it alarms out again.īefore I left last night, I lotod the power and left the cabinet open.Ĭould the issue have been a case of overheating or should I have a technician come in and look at it to see if is another issue. More than likely you lost one of the Izumi 24VDC power supplies.Īnother question, When I came in this morning I powered up the machine and it started up no problem.
