Hello All, I have a Tsugami FMA3 with Fanuc Control milling machine with a little problem, last time I turned it ON the Y axis servo drive had an ALARM 2 code (Low control power voltage alarm LV). I took the driver out and everything looks just fine but the ALARM doesnt get away. I tried changing the command cable to the X axis but the ALARM remains in the same driver. Does anyone knows if there is a way to fix this problem?

What problem. there are more than one listed here. Frontier L what BTW. A L2 I would assume, witch is a SL25, just newer control. The L1 was a small machine like a AL2

Hello, I have bought a VMC with Controller Fanuc O-M the machine is Korean make of year 1993-94. When we started the machine some of the MOVs from the Servo Amplifiers PCB and Main power supply PCB so we changed the MOVs. Now the machine is started and the screen is Showing two ALARMs
i.e
1) 1020 - -O.T
2) 403 - Servo Alarm (VRDY off)
Please some one tell how to reset these alarms.

I used to have problem with the same alarm many years ago, what I did is check and rearrange the power connection then restart the machine. I applied this for Robodrill
