    Question 414 SERVO ALARM

    Help me please,
    My CNC is Fanuc 18M router machine.
    When i turn on power. The machine has an error 414 SERVO ALARM. X,Y,Z axis detect error. I think that is lower DC voltage.
    I see the led on main power is 02
    00 is ready
    -- is not ready
    ## is number code
    Can you help me? How is the 02 code?

    cant remember what 414 is, but Fanuc have good maintenance manuals so you should find one for your machine and read it.

    I had a similar alarm on my Haas we replaced the vector drive and that solved the problem.

    "2" low voltage
    if your drive is A06B-6066-Hxxx check circuit breaker inside the drive and of course all power connections (R, S, T)
    if incoming voltage is OK, then it's needed to check PCB inside the drive

    the DC wires are too thick to be bad, besides you may measure DC voltage on incoming terminals L+ L-
    step 1: measure DC voltage. is it OK?
    no -> the fault is searched, think what to do further
    yes -> go to step 2
    step 2: swap control cables between axes. the fault moves to another axis?
    yes -> the drive or motor is faulty. think what to do further
    no -> the problem is not in drive. think what to do further

    tell what type of axis control card is being used?

    if your SVM has index "HV" his input DC is 600VDC
    if not - 300V
