    Default Robodrill ATC alarm, Spindle rpm issue, Dc Link headachs

    I am having a long battle with a

    Fanuc Robodrill T-14iAL. , 2000
    16i-ma

    Issue 1:
    When i try to start the spindle from stop to anywhere over 2500rpm via MDI, or if by a g-code command in a program i get an EMG STOP ALARM
    433 x-axis:CNV Low voltage DC Link
    433 y-axis. (Same)
    433 z-axis (same)
    7151 Spn 1 : (same)

    On the powersupply LED. 04
    On servo drive LED. 51.

    I can however start the spindle up at up to 2500rpm and tap the override hard key to go ip o 200% with no issues at all?

    I also cannot select the spindle on hardkey on manual controls.. the light on the button comes on but does not turn the spindle on. But unsure if im doing it incorresctly..


    I’ve checked my power coming in and it seems well with in tolarance 208v


    Issue 2:
    At start of a program.

    251. ATC ALARM ( diagnostic # 0100 ATC ALARM (an invalid T-code) )

    I should add that it does do the tool change, just complains right after it that i seem to be asking wrong..

    The code starts like this:

    T01 M06
    T04
    S1000 M03

    Ive tried

    T01M06
    T04

    M06T01
    T04

    T01
    M06
    T04

    But still get the issue... i was thinking it might be my cobbles together post processor.. which seems to have othe issues further down as well.

    Like when it calls M08 for coolant it says improper g-code..


    Any assistance will be appreciated..

    Thanks,
    Jason

    I dont know about your spindle issue. Are you sure your voltage is staying high when you are putting a big load on the drive with spindle acceleration? Is it just utility 3 phase? Not just when you are checking it after it faults?
    Does that drive have voltage selection like the older ones do?
    on the other stuff
    Every Robodrill I have ran, which are all newer. Requires a G49 immediately prior to the Toolchange.
    On the M08 and maybe the toolchange also now that I think of it, check to see if someone in the past hasnt setup a user M code tied to those that are giving you the problems.

    Why are you asking for tool 1 and tool 4 ?
    Disarray is correct you need to put a g49 in first

    Unhappy Re: Robodrill ATC alarm, Spindle rpm issue, Dc Link headachs

    Thanks for the info.

    As for the code calling for a second tool, the post processor labeled "Fanuc 16m" seemed was pre-calling the next tool ? Seems that is incorrect. In the Operators manual it doesn't say anything about that, so I'm guessing its for a different type of tool changer.

    So is this how it might look for a tool change op.



    G49 G80 M06 T01
    M03 S3094
    M08
    G90 G54.1 P00 G00 X-264.89 Y-10.7 (i think the P00 is causing an issue, should it be no lower than P01?)
    G43 Z3. H01 ( it is asking for a feedrate here?)
    G01 Z-.635 F125.
    X-211.55 F4302.632
    X2. F5736.843
    X29.94
    Y-45.038 F127.
    X2. F5736.843


    When I went to try it out I got a new headache from alarms at start up!!

    1003 emergency stop
    1012 in tool change area (although it is not)
    1022 MCC(KM1) is defective
    1023 Break relay defective Z-axis

    Could it be my previous issue with the spindle be due to the MCC (KM1) contactor being about to go out? And no it IS out if i replace it it will magically fix the other issues?

    thanks

    you cannot pre-stage tools on a robo. or any other machine with a similar toolchanger.

    P00 is a bogus call, G54.1 is expanded work offsets. starts at p1

    it may be asking for a feedrate at the G43 because you clear the alarm about P00 with reset and then try to run the next line? And your reset condition is G01? Check your modals.

    where are you located?

    As soon as I get it back on I’ll have a look.

    I’m in Kansas City Mo.

    Where you able to find a solution to these error messages?

    Do you know what the solution was? I am having pretty much the same alarms on a Robodrill Mate.

    What alarms are you having?

    His was a differential diagnosis.

    The spindle accel problem was caused by his phase converter not being balanced well.

    His t code and g code alarms were discussed in the thread

    His other 1000 series alarms were caused by a short or bad connection in the cnc/front panel. He had a broken e-stop button also. He wasnt sure what fixed those alarms. He disassembled and reassembled the front panel and they went away.

    Default Re: Robodrill ATC alarm, Spindle rpm issue, Dc Link headachs

    I am have the following alarms shown under the alarm tab on the main screen set.

    1003 Emergency Stop
    1012 In the Tool Change Area
    1016 MCC(KM1) Is Defective
    1021 KA19 Relay is Defective

    If i go to the "Quick" Display and under the DGN/ALARM tab these are also shown in addition to the ones above.

    1022 KA01-02 Relay is Defective
    1024 KA20 Relay is Defective

    I will start checking connections at the front panel and see if I cant figure out how to test the function of the E-Stop button as well.

    Thanks for the help!

    Ben

    That about identical to his. I think it is a short to ground that causes this cascade of alarms. I have seen this on older machines where a limit switch cable was pulled across the edge of a casting. It finally rubbed through and the machine said every axis was over-traveled in every direction.

    I will check the limit switch cables as well, I was able to force the e-stop through I guess the ladder diagram changing 1 to 0 or the other way around and it caused all of the axis to alarm out in in an over travel state I didn't get those documented before they cleared out though. Fanucs solution is to replace the PCB that the relay is situated on and "start there" where I would rather do a little more research and evaluation.

    Thanks,
    Ben

    I was using that as an example. You dont have limit switches per se. You only have one , for the tool change area.

    Thanks for the heads up on that! I will start checking out the wiring and see if I can find the issue in it.

    Thanks again for all the help.
