I have already apologised on the forum about size of pic it was beacause I was rushing around and forgot to resize it will not happen again , I have found a place in Liecester that supply the fuses am just waiting for them to get back to me , what I have tried in the meantime was I took fuse apart and place a piece of wire one thou thick accross the link where fuse had blown put it back together just to try and see if that was the problem and it was machine powered up as normal have now removed the fuse and will wait until the new one arrives , thanks for you help Rob

Hi,

Is the fuse one of the green plastic ones with a white flag in the window to show the status of it?

I think the fuses are labeled on the fanuc unit.

If its labled 24VE then its the external supply to the 24V I/O

If you replace the fuse and it works great but if it blows again you need to find out what is causing it. The 24VE supplys all the home switches, guard switches etc.

Hi Steve

It is one of 2 fuses for the +24Volts, the other one is a 5.0Amp one, the 3.2Amp one is F13 and the 5.0Amp one is F14, which one covers which side of the 24V systems I don`t know, but you are probably correct.
See image from GE Fanuc site, reckon this is the one!!!

Alan, I agree strongly with Steve, if the fuse does blow again then you need to do some serious checking of all the things that are supplied from the 24V.

Regards
Rob

Hi can someone give a little info , I have a Denford Cyclone on the right hand side of machine is a small cover behind that is 3 batteries , if these batteries are flat will that stop items from being saved in memory ?? if they have been removed will the the memory be wiped clean ??

Do NOT under ANY circumstances remove or try to change those batteries with the machine switched OFF. The whole machine control will be wiped clean!!!

The memory in the Fanuc OT is what is known as "battery backed" and if you let them go flat or disconnect them with the machine switched off you will lose ALL the machine Parameters not just any saved programs!!!

You should in fact have downloaded via RS232 all the Parameters, Diagnostics and Machine offsets programs etc and saved them on to a hard drive, memory stick etc, etc. Copy them to a second or third memory stick, CD whatever, back up the backups!!!

!!! YOU HAVE BEEN WARNED !!!

Rob

5 Euros for a fuse !!! I see Fanuc still know how to charge for stuff :shock:

I'd be sorely tempted to fix the existing one with fuse wire and solder...

With regard to the battery backup.

On the botom of the screen you will see "BAT" flashing if the batteries need replacing.

I would replace them every year as a matter of course.

You have to have the machine powered on before you replace these :!: :!: :!:


If the batteries are removed with the power off or they are allowed to go flat and then the power is turned off.

You will loose everthing stored in the memory including all your programs parrameters diagnostics offsets etc etc etc.

It could take days to sort out if they are not backed up :!:

Yes, they do still know how to charge big time!!!

Having said that paying €5.00 Euro for a correct fuse against the chance of "breaking" a £2800 pounds power supply unit is not the best plan to my mind!! Even getting one repaired would be several hundred pounds minimum!! :mrgreen:

Fuses sorted out and machine is now running as it should , next thing to sort out I am folling the manual that I have and reading about Datum axis , now I have followed the instructions several times and the manual tells me that everthing should read zero now when I check on the screen almost everthing does read zero except for Relative reads X 158.000 and Absolute X 158.000 and everytime I try to datum axis this stays the same , now what worries me is that the manual says that if the valuse do not read zero's that I should contact expert advice so that is what I am doing contacting all the experts out there , all answers gratefully recieved

Press "Menu Offset" key and check the "Work Shift" values, and check what the values are, not necessarliy a problem, just that the previous owner set it up that way. Then set the Z to 0.00 and the X to 0.00 and using MPG wind the X and Z axis at least 50mm away from Zero position, set the "Traverse Feed Override" to about 50~60% and then "Home" the machine again.
The Z axis should then show 0.00 and the X will probably read 158.0, doesn`t matter, whatever it reads write it down and then go back to your "Menu Offset" screen and input that X number in as a Minus - value for the X "Workshift" value and then press the "Position" key and your control should now show "Absolute", "Relative" and "Machine" positions all at X0.00 and Z0.00.

BTW have you downloaded all those Parameters etc yet?? Do it ASAP, you never know, you might just do something like switch the control off because you have got the "LSK" flashing in the bottom right corner of the screen, do that and you will lose ALL Parameters etc from the control!!!

Rob

And remember to write down the 900 parameters which aren't saved (unless you can remember the key to hold down when outputting?)
There are also diagnostic bits, and other bits and bobs to save as well.

have followed your instructions and have now got the Workshift reading both Z & X axis zero ,Measurement reads X axis 28 and Z axis zero , Actual position (Relative ) U 158.000 and W zero , does that make sense to you as to what I might be doing wrong ??

If you want your X axis to show as Zero on the "Position" screen then you missed a bit, go to the "Workshift" and input the X28 value as a Minus - ( X-28.0) and your main Position screen should then show Zeros all round.

The "Relative" Value in "U" is exactly that, a position "relative" to your zero setting.

Have your PC connected via the RS232 and set the DNC sofware to "Receive", then go to EDIT mode on the Operators panel and then press the dgnos/param key and "tab to the beginning of the Parameters, then press the output key, the Parameters should download to the PC, the 900 (900 to 919) Parameters DO NOT download with this method, to get those you can either simply write them down or try using the "Press EOB and Output keys simultaneously" method to download the 900s as well, however it doesn`t always work if you don`t press them EOB slightly ahead of Output and hold while you press Output so make sure you double check that they have downloaded OK!!!

You can do the same for the Diagnostics and all you Machine and Tool offsets, simply go to the correct screen and set PC to receive and press Output.

Double and triple check everything!!!!!!!!!!!!!!!!!!!

Rob

Usual disclaimer, the above is from an old and tired memory, I don`t have the manual with me so if it all goes "belly up" then I only give the info out on a "on your own head be it" basis as a GUIDE only!!!!!!!!!!!!!!!

have got a manual here but could not find out how to save , as for the 900 , in the manual they all appears to be a printed copy of them , so if all else fails I will have to enter them manually

Hi Alan

As there are only 20 of the 900 Parameters it isn`t a big deal to manually input them if you have to but do write them down anyway as they may have been changed from the original Denford installation/commissioning at new, that is what will have been hand written into the Deford Book.

Would that be a Denford Manual or the inch and a quarter thick yellow Fanuc Manual that takes several years to get through???

Rob

have saved all parameters including 900/919 , I have the genuine Denford manual for lathe albiet some refers to the old casettes that were used to save programs etc , and I do have a blue fanuc manual which as you say will take forever to get through , my biggest problem is the fact that I have had a Boxford for some 13/14 years and now I am finding things a little awkward as nothing is done the same way and Boxford do say that their machines are industry standard , I do not think that is quite correct but there that is life I will get my head round it eventually but it takes a little bit longer now as my grey cells are dying off that's the trouble with getting old

Hi Alan

Well, at least it sounds like you are beginning to get to grips with it, seems very hard at first but once you have done a few programs and run some parts off then it all starts to fall into place quite quickly!!

Don`t know about the "industry standard" claims from Boxford but I reckon there are many, many thousands of machines of all shapes, types and sizes out there using Fanuc and machines running the same as the Denford so I would be more inclined to think they would be closer to the "industry standard" than anything!!!!

Anyway, keep reading and happy chipping!!

Regards
Rob

I have backed up the parameters as you said I should but I have had a couple of messages saying back up Diagnostics and machine offsets , machine offsets is not a problem as I am setting them up anyway niether is programs as there is none in there at the moment , so how would I back up diagnostics ?? or is there no need to do this , I just want to make sure that if anything does happen that I have backed up what is required to get me up and running again without to much hassle , and if the worse did happen would I just reverse the way I backed the items up ??
