Rapid Overreide, Fanuc OM

[glovebox20]

Hello

I running a Komo VMC 50 with Fanuc OM control (like the one pictured) and was wondering if there was any way to change the Rapid Override from the Overide Feedrate knob to to the SPEED/MUPTIPLY buttons (circled in red).

I ran a Fanuc 0-Mate control that was setup like this and it made it much easier to operate.

only if its in the ladder...look in diagnostic around 290, press the buttons, see what bit they are, then search that bit in the ladder see if there might be a 'D' address with inverse contacts from the 290 bit to some other bit...(wont be a direct input bit from the rotary, its a 4 bit binary pattern decoded in logic or with a code conversion block instruction to sort out the rov1/rov2 signals.
kinda doubt they have the option in the ladder, but you never know...

if I might ask, why do you prefer the rapid separate? we have a few like that, but usually if we do any work in the ladder side i'll put it on the dial so its more like the bulk of our machines...just curious on if it might be better the other way around, always appreciate any/all input on making stuff easier/faster for production

Ladder..... the kind you use to change a light bulb with?

Ladder's are something I know nothing about, but wish I did.

I main thing I want to do is get the Rapid overide on a different knob as Feed overide so when your proving out a program, you can have your Rapid turned down to F0, but your feedrate could still be at 100% or what ever so you have more time to stop the machine before it hits a clamp or something silly like that.

I don't know who thought combining the Rapid override with the Feed override on the same knob was a good idea. But I guessing it proably the same guy who though it would be a bad idea to have the "Positions" shown on the same page as your offset page, and then have the poor operator thumb the numbers in himself. If that's not asking for trouble, I don't know what is.

By the way tc429, how many CNC machines is your shop running?

Look at post #5 for a pic of Fanuc ladder.

Unless you have a 0C you may not be able to pull it up.
I usually have always implemented both rapid and feed overides by panel switch, it takes a bit more to wire the switch in, but it is nice to have.
The ladder has to be modified though

Hello AL

I've seen the ladder screen like the one in your link while changing the parameters in the past. But I don't undersdtand what I'm looking at other than a bunch of letters and symbols. You could tell me it's written in Geek, and I'd belive you.

What do you mean by "panel switch"?

in our heyday, think they had 1200 people in 5 or 6 different plants, hundreds of cncs, hundreds of robots...by 07 was down to 2 plants, still lots of capacity, about 500 people, then 08 hit and everything ground to a halt...I was one of like 30 left, got moved over to try to keep the one newer plant going with literally zero budget...we did cheapie 'rebuilds' by robbing peter to pay paul , installed/automated a couple lines without buying anything...wasnt easy, but they actually showed enough progress in spite of everything, they got a couple contracts made it thru, came out of bankruptcy and are getting rolling pretty well again. not many private companies can survive bankruptcy...

I'm glad to be back at our 'old' plant now, but 2 yrs poweroff/cold storage really tore up what we had left...everything has needed everything...from polishing/reloading ballscrews, replacing linear rails and turcite, many control-servo-drive repairs, plus all the stuff that was robbed for the other plants...its been challenging some days, but at least now were able to get needed parts, just still gotta be tight budgets for a while...

Well, I did find the diagnostic values for the buttons:
Low1x=294#3
MedLx10=295#1
Medx100=296#1
MedHx1k=294#5
High=295#2

Coolant On=296#7

Not to sure where to go from here.

When I first start the machine it displays:
0466-22
Servo:9040-05
PMC:V1.0-1

Not sure of that helps.

I can see the ladder in the under the DGNOS/PAMM page. It appers to have some seach functions for the soft keys (Top, Bottom, F-search, etc.) but not sure if I can edit the ladder, even if I knew how. Can anyone give me some reference materail?

One other thing that bugs me about this machine is you can not turn the coolant on manualy using the Coolant On button. You have to go to MDI and enter M8. If the Program dose not have a M8, your not going to get any. Would also like to fix this if it's not to much trouble.


tc429, with 100's of CNC, I can see where you would want then all the same if it was resonable possible. I can't even image a bulding with 100's of cnc in it though, but I'm sure there out there. I'm glad to here things are getting better you.
