New yo Forum, I have Fagor experience

[Ringtech]

Hi Everyone, I used to do applications for CMS / upgrade Technologies, I have a lot of experience with the Fagor controllers on lathes, 8025-8040-8050-55 8055i. I do a lot of programming and custom screen programming for the new controls, If I can be of assistance post your question and I'll see if I can help.

Hi Roger !

Check your PM.

Hey Roger,
We have a large Cincinnatti Gilbert horizontal mill with a Fagor 8055M retrofit at work we have been running a couple years. I know you said lathe but I would assume the controls would be pretty close to the same. We have not been able to figure out how to enable M01, no button or switch. Does anyone have any information on where I might look to turn on Op Stop. Seems like it shouldnt be that difficult. Any help would be appreciated.
Thanks,
Bruce

Bruce,

As you may know the M01 is a conditional stop input. The activation keyboard button or seperate hardwired pushbutton is wired up by the Retrofitter and/or Machine Builder. Sometimes they do not do it.... so the customer believes they do not have this feature.

But, you do have it, and it is fairly easy to get running. First thing you do is choose a "free" key, which can basically be any key you're not already using. (Fagor has overlays over the key that are provided with every CNC, thus you should have the overlays already labeled somewhere perhaps ?)

Once you choose the key, look in the appendix of your "Installation Manual".... you'll see pictures of the various keyboards offered by us.... chose the one that matches what you have, and you will see labeled in the manual a # over the key (For example: It may say B13 R562)(This is actually the actual designation for the "6+" key of our most common 8055 keyboard)

That simply means that Register 562, bit 13 is what is activated automatically in the PLC program everytime the key is pressed. Therefore, in your PLC program, within the Main program (After the "PRG" statement and before the "End" statement) you would enter in the following program code:

DFU B13 R562 = set M5031
DFD B13 R562 = res M5031

Thats all you would do, it now works with that key. As a note, M5031 is an internal pre-determined relay type mark for the M01 conditional input, and can also be programmed with the Mnenomic M01Stop in the PLC program as well. You can have this working in just a couple of minutes.

You could also use a seperate pushbutton if you wanted.... with that, you simply need to wire up the pushbutton to a free PLC input on the I/O card.... and set the M5031 instead with a command such as DFU I22 = Set M5031
(DFU simply means detect flank up and DFD means detect flank down of the input or pushbutton)

Its been a while, so I may not have the exact correct code format above, but you might want to consider calling the Fagor Service Department for precise code format at 1-800-423-2467 before you do it.....I think the Register/Bit has parenthesis such as R562(B13) = Set M5013, but do not remember exactly.

I hope this helps !

good luck !
Todd

Hi Todd, thats exactly what I was going to post
M01 is internal to the CNC and as Todd so eloquently described, just add the code to the PLC.

Ok, That explaination is about as good as it can get I believe. I'm going to work with my maintainance guy and see what we can get done on this thing.
Your help is greatly appreciated.
Thanks again,

Hi Ringtech, thanks for offerring.

I'm having a problem understanding 'tangential curves'.

Basically, I have a 40mm Dia, edging tool that I need to curve into the work zone and curve away at the end and thought that tangential curve would do this.

However, with a 25mm straight line to the work zone ( and again, a 25mm straight line exiting the work zone to the same start point ) I select 'Tangential Entry' and enter 25 for "R" ( I understand that this means radius?) and what I see in the profile editor is a half circle along this straight line. ( To me that means only a 12.5mm Radius???) I get the 1067 error when I simulate this of course BUT I also get the same error when I use a 40.5mm radius also????

All I want to do is ease the tool in from about 3mm out and I must ease the tool away from the edge by at least 0.5mm before finishing the profile to ensure that the tool is away from the work zone.

There is something I do not understand about 'tangential curves' so need to 'get my head around' that.

You able to assist with this ?

welcome Todd to the forum.

I have been trying to get WinDNC working with a 8025TG control for some time with no avail. Any experience with this?

hope someone can help. i have a 8055tc controller. message comes up on screen saying "wrong validation code". can you please explain what this means?

[Snapafun]

As you do not appear to have a specific switch for this then you might wish to consider M00 ( or just M0 ) instead. This will halt things until you use the Start button again. Very handy for checking things step by step.
