hardinge fagor retrofit

[Fagor - Todd]

I went out and took a look at the wiring to see what I needed to do to trace everything, and I found hand written on the inside of the cabinet behind the terminal block was the following.

black-forward
red-reverse
red/black-M9
white/black-M8
orange-M12

So I looked for those color wires at the relay strip and traced them to the 25 pin DB connetor at I/O 2 and here is the pinout

3- black
4-red
5-red/black
6-white/black
7-orange

Now I noticed that pin 1 & 2 are jumped together at the connector to a heavy white wire which appears to go to a transformer in the original Hardinge power box. There is also a heavy blue wire that is jumped from pin 19 to pin 20 and appears to go to a connector marked L on the Sabina VFD.

I also checked the fwd and rev on the Sabina and red is indeed reverse and black is forward, just like the handwritten note indicated.

I hope all that makes sense to you. If needed I can check everything more carefully, but as you said there are not a lot of M-function on this machine. spindle, coolant, threading and collet are it.

The Pin 1 & 2 jumpered together is just the 0v power supply reference voltage and that is okay. (pins 19 & 20 is from the 24vdc power supply.... and that is good as well)

Your information is good, we can now set your M-codes.....

Do you know where the M-code table is ? Hit "9" for special modes and then going out of memory, his 2 for M-codes..... you should see an M-code table that probably shows M?? and then followed by 15 zeros on the top row and 17 zeros on the bottom row.....

You need to set-up the following:

M03 - 100000000000000
01000000000000001
M04 - 010000000000000
10000000000000001
M05 - 000000000000000
11000000000000001

The above are for Spindle control, and just so you know what is going on..... the top line designates the output it turns on when you execute an M-code in your program, the bottom line indicates what that same M-code output turns off..... you'll notice above, the M03 turns on the first M-code output (pin 3), but turns off the 2nd M-code output (pin 4) Therefore, M03 and M04 cancel each other as they should.........you'll notice that M05 doesn't turn anything on, it just turns off either M03 or M04 if they were on.....

On that model, there is 15 dedicated maintained outputs you can use for M-codes..... but, you will notice that there are 17 digits in the bottom row...... this is because the last two digits (far right) have different meanings..... Bit 16 indicates if that particular M-code is executed at the beginning or end of a block of code. (0 = beginning, 1 = end) For example:

N10 G01 X50 M03........ if you set the parameteer to zero, then when the CNC got to this block of code, it would first execute the M03, thus turning on the spindle and then would position to X50 (As most M-codes are done).... but it is your choice.

The Bit 17 (last bit on the right) indicates if after executing the M-code if it has to wait for the M-done signal to (via the feedhold input) to transition before it continues in the part program. (0 = wait, 1 = do not wait) In your case, I have these set at 1, do not wait. Most you do not wait on like coolant or spindle control...... but there are cases you have to wait for confirmation before continuing on in the program. (Example: Auto Turret, where it fires an M06 Tx and then waits for confirmation from the interface that the tool position has been reached by the auto turret)

I do not remember for certain.... its been a few years since I plowed into a CMS interface, but I do not believe they are awaiting confirmation from any of the M-codes, but I guess you'll find out. But, in any regards, it is your choice, but if you choose for it to wait on any particular M-code, the interface has to be wired to give this confirmation via the feedhold/m-confirmation input.... (Pin 15 of I/O 1)

With that said, your others per your information is:

M09 - 001000000000000
00010000000000001
M08 - 000100000000000
00100000000000001
M10 - 000000000000000
00110000000000001

I am guessing on the M10..... I assume that will shut down both stages of coolant... which is what I believe the M08 and M09 are.... but verify by hard connections.

M12 - 000010000000000
00000000000000001
M13 - 000000000000000
00001000000000001

I believe going out of memory that M12 was open (or shut your air collet) and I believe also going out of memory that M13 would turn off M12, thus shutting your collet. But, you will know which is which after you execute one.

M30 - 0000000000000000
111110000000000001

This last M-code is for your M30 end of program command, all it does is shut down anything that may have been left running as you can see by the 1's in the bottom row.

After changing all of your M-codes, hit the reset key and then via Teach-In mode, (MDI type command mode), execute some of the M-codes and see if you get the desired effect.

As a note, there are machine parameters that are involved with all of this that must be set-up correctly.... I am assuming you have those set correctly already from a list ?

Hope this kind of helps.

good luck !

What is the actual procedure for entering the code?
Do I just type M03 100000000000000 01000000000000001 and then press enter?

Prior to this I have tried M03 recall and M03 enter, but that didn't do anything

the other machine parameters seem to be ok, but I will go thru them and see if they make sense

[Fagor - Todd]

Tim,

Yes, you should just be able to key in M03 and type all of your 1's and 0's..... if it does not do anything, this indicates to me you are locked out of them.

(Did you have a battery failure ?)

You enter in a code, I think PKAI0 or PKAIN I do not remember which (Its been many years.) But, these lock and unlock codes are listed in the manual......I just have to remember which mode you enter them in as well.

What happens when you loose our batteries, memory scrambles and locks you out...... its no big deal, you just have to enter in the unlock codes. I recommend you call our Service Department at 800-423-2467 and ask them for the memory unlock codes and where to enter them......

Sincerely,
Todd

[Fagor - Todd]

btw, ask for Patrick in service department.... he does the bench repairs for 8025 controls and knows the lock/unlock codes by heart..... tell him you have the 8025 T... they are different codes for the milling. There are two different codes you need......

[Tinmuk]

I did have a battery failure, that's what started this whole mess. I do have the unlock codes in the manual. I will try all this out this weekend and hope it works.

After I get all this done I will will start on the Z axis following error i was getting prior to the battery failing......

Z axes following error is simply the CNC telling you the Servo's are not keeping up with the command. Get your parameters set back to what they were..... if you do not know what they were, you'll have to go back thru each one at a time. The parameters are set by the builder as per their machine configuration and preferences..... you have to figure out what they were doing. When you have questions, call our service department.

As a note, those K1 and K2 parameters are very important for servo performance and to close the servo loop, the directional parameters are extremely important.

good luck !

I have a Accuslide and Fagor 8025T and the collet open/close is M12/M13.

[Tinmuk]

ok, i have tried every way I can think of the enter the M-codes, but the controller won't accept them. I know the unlock code works, because if I don't enter it I can't even type the 1's and 0's. When I enter the unlock code (opmode 6) it will let me type in the code, but when I press enter nothing happens.

The checksum error is always present, does this indicate a bad memory location? Would downloading the parameters and reloading them help with this?

Are you typing in all of the digits ? Even if it is just a zero, make sure you type them all in then press enter and then press reset twice after all are entered.....

If you makes you feel better, I've worked on literally 100's of 8025's and never had one with a hardware or software problem that prevented me from entering those parameters..... (Once upon a time, I was the primary bench technician for Fagor USA that fixed all CNC's that came in the door) .......thus I am sure nothing is wrong with them.

Let me know if you're still having a problem tomorrow, I'll actually look at it closer with you and open the manuals and make sure you are entering the right unlock codes.

good luck !

Hey Todd,

You're amazing, you got my Fagor to accept the code psychically! But really, I tried it again just before I went to work this morning and it accepted the M03 code. So tonight I will enter all the M-codes. i don't know what I was doing wrong all week but it worked this time.

However, after it took the M-code, I got a error 108, leadscrew compensation error. when I checked the leadscrew compensation table there was a checksum error there also. I will try to reenter those tonight as well. even though there are numbers already entered. anyything special I should know about that?

[Fagor - Todd]

Hi Tinmuk,

I'm glad to hear of the new progress !

What has happened with the Leadscrew error compensation table is that it when the batteries went out, it scrambled, thus a checksum error. All you have to do is reset the table.....

I think there is a single code for it where you just enter PKAI0 or maybe just PKAI with them.... might also be MKAI0 or MKAI..... its been a few years since I worked on that control and do not remember the exact code..... (I know MKAI0 is for unlocking memory.... you'll need PKAI0 for unlocking parameters) and it might just be KAI0 that resets the leadscrew error compensation table...... but it should be in the manual. You will also more than likely have tool table and zero offset table errors. With those, you should just have to change one and they will all reset. Just takes a few seconds to clear these parity errors and they are normal after losing the battery back-up.

You might want to call Patrick in the morning at 1-800-423-2467, ext 288, who is our chief Bench Technician and will undoubtly know the codes out of memory considering he uses them on a daily basis. Tell him you have an 8025 T CNC so he'll know which code to give you.

good luck !
Todd

ok, the leadscrew error 108 is fixed, very simple I just entered the existing numbers. Had to do it twice, but it worked. The control now starts with no errors. But when I go to op mode1 thru 6 I get a LAN error (111)

So what do I do the resolve this?
