    Alarm 403: VRdy off , Fanuc OM

    Hello,
    I have big Problems with my "new" Hobby Machine:
    I bought a OKK, with Fanuc OM + PMC, AC Servo, `90th Sporadically, I can not turn on the machine, it comes, the alarm 403, less often, the alarm 401 The machine has connected only 3 axes, according to the Manual, the alarm 403 for the 4th Axis??
    But sometimes not, turning on, then the machine is working properly.
    I already have all the cables, the connectors, fuses, checked the voltages and compared, are all ok The release voltage is forever.
    For error description:
    If this error occurs, go to the Servocards, the LED DRDY very briefly (one tenth of a second or so) lights and go off again, and the error message comes directly on the screen. Somehow it looks to me as if a contactor does not stop there?
    Can i turn off the VRDy Alarm? Ignore or so?
    Thanks from Germany,
    Thomas

    In the meantime I have replaced the capacitors, as it was not tuned well.
    I'm still in search for the sporadic errors. Unfortunately I can not installed in the OM software switch the "Ignore VReady: off" it was only at later Versions.
    Someone else an idea?

    simple... there is same old version of software who says al 403 ,not for the fourth axis, but for the third (Z) axis ...So, if your servo amplifier is one 6058 series, exchange contactor ..

    kongdamdau...... 10xx numbers are PMC errors and should be in the OEM operators manual, most likely a switch or something.

    Hi,
    I believe I have solved the problem: When you switch on, there was too high Inner resistance at the fuses, there was micro welding at the caps. Since then I've fixed it, (i have polished the fuses) no error occurs more. I had previously changed all assemblies, unsuccessful!
