    fanuc 6m locked parameters

    Hello,

    I have fanuc tape center model d with fanuc 6m control.

    the bubble memory has crashed and I replaced it with a new one.
    and I have put in all the parameters bud I can't change parameter 120 and 122, I need them for the tool change.

    I think that the are locked and the can only be changed by setting another parameter,

    does anybody has an idee?

    Greetings albert




    machine data:
    Fanuc tape center model d
    6m
    Series m63
    Typ A04B 0034 A003
    Ser 530432

    I'm assuming your manually entering them. Sometimes the order parameters are entered matter.
    Try loading the correct full parameters from a backup via rs232 or a memory card.

    hello dpuch,

    yes I did it manualy.

    I don,t have a backup on the pc. I have tried to change by pcload, the communication works, I can change everything while adjusting parameter on pc and send them by rs232, but I can't change 120/122/123 it remains 0.

    I think another parameter must be set. bud I don't know wich.

    do you have another idea?

    You may try clearing the memory again (remove the module) and starting fresh. Manually enter just the rs232 settings, then upload the complete parameters.
    If it requires a setting to be something besides 0 before it is uploaded then I do not know either.

    he mentions he doesn't have a backup on PC.
    I agree uploading the parameter file is a possible solution.
    it could be as simple as punching out the parameters, edit and upload.
    to do that, go to EDIT mode, press PARAM, type P-9999 then PUNCH.
    then edit the file, save then read it back into the machine by going to
    EDIT mode, press PARAM, type P-9999 then READ

    Re: fanuc 6m locked parameters

    hello fordav and dpuch,

    i have erased the memory, so all the parameters are zero. and i have set only the rs232 settings in de parameters, and then i have upload the parameters by pc.
    everthing is written bud the parameters 120/122 not, the can,t be changed.

    the error is : 451 t servo

    what i could find out that its for toolchange, and it needs parameters for that.

    any idees?

    Re: fanuc 6m locked parameters

    You problem probably is not with the loading procedure, but you might review www.tulipmemory.com M100700D - TULIP for Fanuc 6, 11, 12 Manual.pdf where it talks about manually loading the control to make sure.

    Other than that I guess reading thru the 6m paramters manual and reviewing the entries are correct.
    Sorry I can't be of more help with this one.

    Re: fanuc 6m locked parameters

    are you sure you did the correct procedure to manually change parameters?

    the procedure is....

    Put Parameter Enable Switch ON
    Put Mode Switch to MDI
    Press Function key PARAM
    Type N then parameter number then press INPUT (in this case parameter number typed is 0120)
    Type P then numerical data then press INPUT (type the value you want to put in parameter 0120)
    Put Parameter Enable Switch OFF
    Press Reset.

    does this work on your machine for parameter 0120/0122?

    Re: fanuc 6m locked parameters

    yes, that is way to do it,

    it works for every paramter but not for 0120 and 0122

    Re: fanuc 6m locked parameters

    fordav, these parameters are not listed in the 6m manual, but are for the 6t-a as max. spindle speed for gear changes.

    Re: fanuc 6m locked parameters

    yeah I see they are unlisted. he wants 0120 and 0122. no idea why ;-)
    either way the procedure above should work, regardless of the parameter number.

    Re: fanuc 6m locked parameters

    its an old and uncommon machine and I think you are out of luck. your only choice now would be try to contact other owners of the same machine and get a parameter backup.
    try searching for "Fanuc Tape Center Model D" and PM the person who posted. or look wider on the net for other owners of that machine.

    Re: fanuc 6m locked parameters

    if there is a tool change macro it will probably be numbered 9000 or higher.
    you need to unlock the 8000 range and/or 9000 range programs by setting parameter 318.7 or 319.7 to 0 then power off/on and you will be able to see all the programs in memory. then just punch out the program you need.
