Hello.

I heard once that chancing one bit on parameters gives more memory to fanuc control. Does anyone know more about that option?

AFAIK this requires additional ROM chips to acquire, as well as the option.

[Al_The_Man]

Check parameter 901 bit 1 = 120m. bit 2=80m. bit3 = 40m. bit 4=20m.
If you do require additional hardware memory, look up Tulip, they make memory add-ons for Fanuc.

Requires extra RAM chips. If you turn on the option bit for more memory than control has chips - you will get a 910/911 RAM memory alarm and will have to dump all memory - not pretty.

There's now 20m memory. I remember that he said that he know how to double up memory size by chancing one bit. So propably there's 40m memory installed on board.

[la_coterie]

I think my Fanuc had 20M when I got it - I now have 80M just by changing the parameter, you're likely to loose any progs on the control & while you're at it backing up the parameters wouldn't be a bad idea... oh the 900 ones don't get backed up so out with pen & paper...

do a search for fanuc memory on ebay there's a guy in canada doing a memory upgrade to 320M for 250usd.

There is a way to output the 900 par. I will have to check my notes Monday.
The Canadian reference is I think the one I mentioned in post #3, Company called Tulip.

When punching out parameters press EOB and output start, this will send out the 900's also. Check out www.memex.ca thats who I use for memory upgrades.

I can sell you the stuff need for upgrading to 320M for $250 also

I just did this upgrade today-original machine had 4k upgraded to 80m (16k)
This requires no hardware, only above 80 requires additional chip's.

Cost from Fanuc $297.00 they email you a couple of file's (like the old EZ opt) and you follow the read-me file and down-load to the serial port

I have a OT and a 6M-b how do I make sure I have all my parameters backed up for each. Thank you , Drew

[Al_The_Man]

0T Set up your PC to save, Go to EDIT mode press the dgnos/param, parameters and then output/start key
If you want to output the 900 parameters also, press and hold the EOB key when pressing output/start.
On the 6T mode to EDIT -9999 then output (punch).

Thanks Al btw did you see my post about my Burgmaster tool changer/homing problem your input would be apperacted.
It started working right later in the day.Turned it off and on several times. But it has me worried! And are there options for retrofiting using the DC servos and Amps maybe also using the fanuc encoders too.

Hi, Al

Is this parameter good for an 18-I TB on a Lathe????

I checked this parameter out and there is all "0" on the 901 parameter.
How can I find out if I have the extra RAM chips on the board before I try to turn the feature on?? I dont want to lose anything!!!!!!!!!!

Thanks

[theemudracer]

???????

[Al_The_Man]

The 16/18/21 I have show P9921 bit 0=640m, bit 1= 320, bit 2= 160, bit 3= 80m and bit 4= 40m.
I am not that faimiliar with the 18 to tell what memeory you have, you could make sure you have the parameters backed up and change one at a time.
Al.

[theemudracer]

If I go to the directory and look at the used space and the free space, and add them together, how does this equate to the "M" value???? Or does it???


thanks
Jon

[Al_The_Man]

The M number is a throw back to tape reader, and is Metre's of tape.
I believe 320m = 128k and so on.
Al.

[theemudracer]

are there any parameters that are not saved by punching parameters???

I recall on the O contol you have to push EOB-punch to get the 900 parameters.

Anything like that on the 18 that you know of????

[Al_The_Man]

I couldn't see anything in the 18i manuals, try punching them all out ALL and see if the 9000's are there, other wise you could try the -9999 to see if that works.
