parameters and settings

[DerHammer]

I have recently acquired a replacement master board for my Fanuc 0ma control, which died on me a couple months ago. I installed the replacement board, powered it on and it seem to come back to life. I then proceeded to reloaded the parameters that I did have backed up, which seem to move along fine. The three problems that I am having now are inputting the diagnostic parameters if needs be, resetting the soft over travel switches and knowing the correct settings for the "settings 1" menu.

Diagnostic parameters - I was told by the Fanuc tech that the only diagnostic parameters I needed to set were those above 300. Oddly enough though, there still seems to be diagnostic parameters in there and furthermore, when I enable Estop and set the PWE, it still wont let me input anything. After entering my bits, I hit input, my digits disappear but nothing changes, which probably means that its not supposed to be? When my machine went belly up, I did not have these diagnostics backed up but I found an identical machine in California and the gentleman was kind enough to email his. His machine is the same model, same control, same servos. The part which is scaring me is that only some of his diagnostics match those in mine even despite being the same machine. The replacement board came out of a lath and of course, I had to match my jumper settings and move my E-proms/memory over but I'm a little unclear now as to what I should changing in the diagnostics if any once I figure out how to make the control let me.

Last two problems are shorter I hope. I've tried to jog the table around since powering on but the soft switches are tripping immediately, in particular the -X direction. I've tried the Cancel/p combination at start up in hopes to reset this but it doesn't appear to be responding, so I'm not sure where to start. That key combo has always worked for me in the past but now it doesn't seem to be, which I suspect may have something to do with the parameters or settings.

Last but not least, I am not sure what I should be going in the "Settings 1" menu. Would any of you experts out there happen to know what the settings REVX, REVY, TVON, ISO, INCH, I/O, ABS, SEQ etc are supposed to be on an 0ma? As always, any assistance is greatly appreciated.

a number of diagnostic parameters can not be changed- they are for displaying
the status of inputs and outputs.
Call me during EST working hours and I will see if I can help.

Thanks for the info everyone as well as the contact phone Bill. I wont be home for most of today but I can give you a call later tomorrow or Monday if I can't get it figured out before then.

Since posting, I was told that only some of the diagnostics can be changed but not many. From what I understand, the later numbers are related to the machine option hardware such as the automatic lube system, etc. My machine is very simple like that though IE no tool changer or 4th axis, so it makes sense that almost all of my diagnostics are all zeros after 300.

The biggest issue that I'm having at the moment seems to be getting the table travel back in order. I currently have No travel at all in the -X direction and the homing function seems funky. Typically when homing, the table moment should get close to the end of its throw, slow way down and then reverse off and call that home. Currently on the Z and Y axis, it drives all the way out and throws the soft switch instead. My guess is that the soft limit is probably tripping just before the machine is getting to the point it needs to home at but I'm not certain and hoping to get a second opinion.

I have re-checked all of my parameters against the back up I outputted from the machine when it was working properly and I have not been able to find any typos, so I do not believe this is the issue. I don't understand exactly how the parameters could be wrong being that there in exactly how they were before the breakdown but the fact that the cancle/P key combo at start up isn't working tells me that more than likely the issue has to be somewhere within them right?

Would anyone happen to know what parameters control the soft travel limit travels on this control and if I tamper with these, will this wreck havoc on the machines ability to home properlly? Again, thanks goes out to everyone for the advice offered.

I had the same sort of issues when I scratch built my 0M-B and now my current 0M-C control from stuff I bought off of ebay. I had to build the parameter tables, diag parameters, tune the servos, even scratch built the PMC ladder.

Boy I tell ya, having to spend about $500-$1000 on each card/module for the 0M on ebay beats the FANUC prices.. and most of the dealers that sell FANUC stuff are pretty reputable. Just pays to have the right part numbers and manuals in hand before doing so though. Most of them are listed in the manuals.

EDITed, **many of which are PDF's under 5mb. He's helped me out a lot. A very helpful and knowledgeable person. I'm not sure if he has the 0M-A or B version manuals. I gave away mine to a friend who took my old 0M-B control. Whats great is that I have the color 14" CRT/MDI and the Op. panel with the updated keypad. I also have axcess to 8 seperate axis'

http://www.fanuccables.com has a great custom cable service I used. They made all the right cables and helped me get them set up with the additional help of the manuals. Fill out and fax their worksheets to them and they will email or call you back.

I can probably help you out too.

In the last my post I've forgotten to write the PDFs fix only one your problem, sorry.
Diagnostic parameters above 300 are timers and counters for your PMC.
Which axis is your table? B-axis? Where is connection between table rotation and X-axis. May be anything wrong with assigning the axes?
In attached PDF information about soft limits.

Mine is the normal set up: X, Y, Z and the 4th axis is either A, B or C. I usually hook my large (over 15") rotary table to it.. but I have used other accessories on that axis.

I wanted to pop in and post a quick update for those watching this thread. Since posting last, I was able to get my soft limit issues resolved for the most part. I found the parameters I needed to a manually set the soft limits way out, so that I could re-home the machine and this seemed to have done the trick. Unfortunately though, My cancel/P command still isn't working at start up, which as most of you know is a great shortcut to fixing this problem if it ever gets wacky again in the future but at this point, its a minor complaint. It does make me kind of wonder if that could be on account of the board revision code being slightly earlier than the board that was in the machine prior(I went from a 006 to a 003).

I think that I'm getting pretty close to making chips again but the issue that I'm running into now is that for some reason, when I DNC a machine program over and run it. My Cross travel(Y) seems to move in the opposite direction as it should when running the program and I'm wondering if anyone knows if there is a quick setting somewhere on it to reserves this?

As always, many thanks goes out to everyone lending a hand.
