dnc on the lathe

[Beekeepr]

Has anyone tried to run a program on the memory flash card. The control is a Fanuc 21-itB. If so how can it be done. The operator's manual does not help. The file is to big to fit into memory. Thank for any assistance

I have tried so of the things listed but still no progress. I can input/output programs but I can not run in dnc mode. One example give me how to set channel and go into dnc-cd mode but I can not find dnc-cd. Maybe I am

If you want to run off a flashcard you have to set the I/O for 4

 

#20 should be set to 4

 

There are parameters that need to be set to facilitate this also.

[Beekeepr]

It is set to 4 where am I going wrong. Is there some other parameter I need to change also.

ATA DNC, Sub-program Call, Fanuc 16/18i controls

 

Parameter Settings: #138.7 = 1

 

DNC operation with memory card is:

0 = disabled

1 = enabled

#3404.2 = 1

 

Address P in M98 block of subprogram call function is:

0 = indicating a file number

1 = indicating a program number

#6300.4 = 1

 

External program number search

0 = disabled

1 = enabled

#6080 = 0

 

I/O Settings:

Channel = 4

 

ATA Card:

File name on card must match program number, DO NOT use filename extension. (.txt)

Example:

card filename - O0001

program number - O0001

 

Use % at beginning and end of program file.

 

Program Call:

Create program in NC memory:

 

%

O0001

M198P2 (calls O0002 on ATA card)

Dave,

 

read the link given above. We go pretty deep into flash cards as well. You don't always need to spend big $$$ for those things. I spent like $45 last year for a 128MB card and adapter. I use Compact Flash and an adapter.

[smokey_44]

The flash cards that we bought ( i was not involved) are "old" and they dont make them any more so thats why I said about $$$$ if you buy the wrong ones they go outta date quick. Thats whats happened here. They thought it was easier to goto dnc.

I cant get to the link by the way they block access to the internet and allow only certain pages to get thru ....Not that link of course...

[within a thou]

1 go to MDI

2 offsets

3 enable write

4 turn IO to 4

5 disable write

6 go to Memory

7 DNCCD

8 Turn on drip feed

9 choose program number

10 Dnc start

11 hit cycle start

 

You do NOT have to change the program name to a O#### but you do have to use that number to call the program.

 

Try using your page up and page down or the "+" key at bottom right hand corner of your control This is for my 18i so you may have a diff step or 2 in finding dnccd but as soon as you are there it will read the O#### number of the program with a value of 0001 , 0002, etc beside it so when ya type in that number then hit the dnc start.

 

I would also suggest putting your feeds and rapids to 0% in case this thing takes off on ya when ya get it right unexspectantly
