I do not want that M30 opens the chuck

[fomaz]

Hi.
In a lathe that I am trying to make it working (2nd hand), I am trying some code. Until now I find strange that the end of program (M30) makes also the hydraulic chuck to open.
I did not machine anything yet, but piece will fall for sure. This does not make sense to me... I see now! The machine had a part catcher... does not have one now and I don't want it also, and I want that the part would stay on the chuck until I open the door.

Where can macros be changed so that this will not happen? Only in the ladder?

Thank you

You do not say what Fanuc control it is?
On a 0T, to edit the 9000 macro's you turn off bit#4 in Par0010.
Turn it back on when done to avoid accidental erasure.

Look for the parameters where M-code numbers are specified for calling a macro/subprogram through M-codes. One of these may have 30 stored in it. Just delete it (make it 0). This would restore original meaning to M30.

It is 21TB.
Thank you, I will try to understand what are the 9000 macros

Sorry for my ignorance, those parameters are the same that are present in the parameters manuals? Sorry if my question is completly strange.

[sinha_nsit]

yes. Look into the parameter manual.

are you sure M30 opens the hydraulic chuck ?I may be a different M code
I think you should check the ladder

[sinha_nsit]

It is possible to redefine any M-/G-code, which makes them call certain macros/subroutines. Possibly, M30 has been redefined on his system.

Please see attached photo. I belive that this is what you mean, but no 30 was found on the custom macro pages, only 19.

Yes, I am sure since I am only testing the machine with a small program, and only contains a few moves and then the M30. The ladder have a lot in Germany since the machine is an EMCO. It is at least difficult. Neverless, I will try.

M19 call program 9020 if you have not used the M19 in test program don`t
change param. 6080

[sinha_nsit]

M19 has been redefined, but not M30.
If you intend to use M19 with its original meaning, set param 6080 to 0.
Regarding M30 opening the chuck, a possible reason is some change in the ladder.

Thank you for all replys.

I made some progress and I belive that I found the ladder steps that make the chuck open at M30.

My first time changing the ladder on a fanuc was with a compact flash with an adapter to PCMCIA on a different controller. The controller accepted the card and everthing was fine (on a 21i-M). I edit the ladder on the computer, transport it to the controller using the card, and then I save it to the controller.

On this machine (21-TB); however things are diferrent: machine does not recognizes the 2Gb card that I used on the another controller.
I have tryed with a smaller compact flash (128Mb), when trying to format it on the controller, some message appears saying that the "memory card battery" is damaged.... battery on the memory card ?!
Continuing to try, I found a series 2 intel flash card with only 2MB. This card accepts the format and backup from the controller, and I can read it on the PC. Everthing appeared to be correct. When was time to save a file to the card using windowsXP, the card accepts the file, I press remove harward with safety. Ok until now. I put the card again on the computer and no file is present on the card. I tested with 3 computers...

Basically, I cannot write to the memory card on the PC, but can read; I can write and write to the memory card on the machine controller.

There is another way to change the ladder on the controller? Can I connect directtly the fanuc ladder editor to the controller using RS232?

I should add, that I can send and receive programs between PC and controller. Could I also edit the ladder ?

Thank you very much,
