Fanuc 18MC, alarm 004 ADDRESS NOT FOUND

[ddanutz1]

Hello,

I am trying to get a Fanuc 18MC running, after reseting parameters.
It might be possible that also some other information was erased. Control seems to run ok, i can home all axis, i can run the spindle. Machine does not recognize the M6, and outputs: "004 Adress not found" error.
As i remember, during the M6 call the machine was running a macro program, where should this program be located?
There are also other Ms not running at this moment: M8 for example

Thank you for your help,

Hi, i did some progress by creating O9001 macro program.
Now, controller stops when reading M66...what does M66 mean?

Thank you for your help !

The User Macro for tool change etc are normally in the 9000 plus program area. In most cases these programs are protected by a parameter setting. To enable display and editing of these programs set bit 4 of parameter 3202 to "0".

If you have only reset the parameters and not the total memory, the 9000 series programs should still be intact. See which program contains code that will execute a tool change, it should be commented what the various programs do. Noting the program number, go to the parameter number that relates to it as shown in the table below, and check what, if any, value it contains. As you have reset the parameters, it should be blank. Set this parameter to 6, as in M06, and try the tool change again.

What other M functions apart from M08 are not working?

Bill

Hello Bill,

Seems that the parameters are ok, i got a reference for M6 to O9001program.
I did some manual operation to the ATC, using the M21/M22 codes, the tool-change operation works now.
There is a strange behaviour that never happened by now, spindle does not orientate at correct position, each time it is a different position, not constant !
M8/M9 still not working, but that should not be critical.
Any ideas here?

I should say the machine has serial communication port damaged, i cannot do anything with it, i tried on channel 0,1 also channel 2 by changing the cable position on the controller( cable works fine, communication software the same, just tested them on another machine). The only port i have is ethernet, through DataServer, channel 5. I was able to punch parameters from/to CNC, and this also raise another questions:
- if i use the parameter file that machine punches, make some small modification in it, i am able to read the parameters back into CNC(file went to ftp, and then back again)
- if i use the parameter file that machine came with on CD, i cannot read the parameter. Also, i have two files machine came with: one is aprox 40kb(paramters up to 9998) and 90kb aprox (parameter up to 20000. aprox). which one should be used for reading? Opening files with notepad they list differently, none of them looks like the one coming from CNC. The parameter file coming fresh from CNC has continuos information, no different lines, the other from CD appear listed each paramter on different line...

Is it possible that i did something strange also on the PMC side?
Any ideas with the spindle orient randomly issue?

Thanks for help !

Hello again,

... i have uploaded by DataServer the paramter file machine came with on CD, changed the header, and now machine is in original state.
M8 works fine, toolchanger and spindle-orient the same.
Thank you all for your attention on this thread, many thanks Bill for your fast reply.

I only got to read your penultimate post a few minutes ago. Glad you were able to get it sorted. I was unaware you had the original parameters. I was going to suggest that once you got things right again to download a copy of the parameters as insurance against future catastrophes.

Its nice to see you have the machine working well but you might have to check you backlash setting to make sure your slides position well , para 1850 should be where your adjustment for backlash is stored.

[gbowne1]

Yeah, I was thinking you might need to make sure you have your backlash settings correct. And, yes, from what I read.. it is the parameter there is the 1850 that you can adjust as was just suggested.

My reference shows that parameter 1850 is Grid Shift and Reference Position Shift for each axis.

Parameter 1851 is Backlash compensating value for each axis, and if bit 4 of parameter 1800 is set to 1, backlash compensating value used for rapid traverse for each axis is set separately with parameter 1852.

With regards to the Reference Position:
Unless you have a Sub Plate on the table that has a Reference dimension of a particular value from Machine X Y zero, then the only really important axis to have the correct Reference Position is Z. The tool change Macro will probably use G28 or G30 to ensure the spindle nose is in the correct position relative to the tool changer arm. The position for G30 is a relative distance from the Reference Position; accordingly, if the Reference position is wrong, then both the G28 (Reference Position) and G30 (2nd Reference Position) will be wrong. If the Reference Position is a little bit out, the machine will still tool change, but the tool change arm mechanism may have to flex a bit to accommodate the small misalignment. In the long term, this will be detrimental to the machine.

Having said all that, and given that you have the original Parameter settings, as supplied with the machine on CD, its a reasonable chance that the reference values will be correct, unless the machine has had a prang, or the encoder has been moved for some reason. In any regard, it takes a relatively small amount of time to check these points and know that they're right, or wrong.

Hello all,

Thank you for your posts, actually, the only two parameters
i had to change were the 1850 on Z axis to get nice smooth toolchange, and 3104.6 to display programmed Z on absolute coordinates.
I wasn't sure myself i had the correct paramaters, and most delicate, i was aware that the serial connection is out of order. I had luck i worked with the Dataserver through ethernet....
Backlash i will check later, during some precise machining, now i need to make some big chips !
Again, thank you for your support, great forum, nice people !!

Regards,
Dan
