Hi,

I have this problem in a Yang Lathe with a Fanuc O control,
the M01 optional stop is not working.

It only works if I program it directly after a M00, like this:

T0100
G97 S300 M3
M0
M1
M1
M1
M8
M30

If I remove the M00 the program ignores all the M1 and jumps directly to the M8.

In the above case the M0 is halting the program. Are you saying that with the M0 programmed, the program then halts again at each and every M1 that follows, and that without the M0 all M1s are ignored when the Optional Stop switch is set to On?

Look for an optional stop button in the MDI panel. M01 is programmed in the ladder.

[CNC Data]

First off i am assuming the OPTIONAL STOP button is pressed?

Check to see what the X input address of the button and F154#6 are doing. It looks like your problem is in this area.

[erd39030]

Thank you guys, for your fast response.

Yes, the Optional Stop button is pressed (and iluminated too)
Bill, that's right, the program stops at M00, then I must press Cycle Start at each M01.

If I remove the M00 then the program ignores all the M01.

Look at this program:

M00
M01
M01
M03
M01
M01
M30

The program halts at M00 and the following two M01, then starts the spindle and ignores the rest M01.


CNC Data,
the maintenance manual (B-62545EN/02) says that the signal are F154.6 for M01, and F154.7 for M00, but neither one appears on the ladder.

When I press the Optional Stop button, then the line S075 iluminates complete.

The line S076 does not close. The contact M01 (R602.7) closes only if I let the cycle start button pressed by several seconds.

Is anywhere a parameter or a timer for the cycle start button?

Thanks for all your help:
Everardo.

[viorel26]

which element is not iluminate in line S076 (X8.6; R602.7; X0.5; F149.1)
What is X0.5

[erd39030]

The R602.7 and X0.5 are remain off.

The X0.5 is the Cycle Start button. If I push it for some seconds, then the control recognizes the M01,
as if the ladder ran trough the S076 line before the signal R602.7 from line S074 had time to arrive.

[viorel26]

I think the problem is X0.5 , maybe is remain blocked
check in diagnostig page for x0.5 it should be 0

[alexfanuc]

Could be the cycle start button has a problem, but just check if you mistakenly activated the single block button (SBK).

[erd39030]

Well, I am sure that it is not the Single Block.

And I am not so sure about how to find the diagnostic related to the X0.5.

I didn't had time today, but tomorrow I am going to dismount the panel and look how it is connected the Cycle Start button. I noticed that the button is not lighting, probably the lamp is burnt out. Could that cause a problem?


Anyway, thanks everybody for helping me. I will keep you informed.

I am also working in three other "projects": Trying to resucitate a 1990 Haas VF-1 that freezes with no alarms, an old chucker lathe with damaged dc drives and attempting to use a renishaw probe in a Yang mill with O-MD control.
Surely I will learn something, someday, somehow, out of this. :idea:

Pushing the parameter button twice takes you to the diagnostics screen. Diagnostics will be shown in the upper left of the screen. Look at the diag x0 and it says bit #5. For example X0 = 00100000 in this case bit #5 would contain a ONE.

[erd39030]

Mmmm... So X0.5 is related to Diagnostic 0 bit 5 :-)

Now it makes sense.
I was completely lost looking at diagnostic 5.

Does the same applies to all signals (R,G,S,F,X,Y)? Or only to X & Y signals.

Well, signal X0.5 is set to 1, and changes to 0 while I push the cycle start button. Does it means that the pushbutton is inverted? That it should be a NO instead of NC?

Thanks so much:
Everardo:cheers:

[alexfanuc]

When pushing the cyclestart button you should see a one in diag. X0.5.
Regards

[erd39030]

Fixed! :-D

It was the cycle start push button,
wired NC instead of NO

Why? Only god knows!

Thank you Alex.
I owe you six tecates. If you are in Ensenada B.C. area,
you are welcomed to cash them anytime. ;-) :cheers:

Best wishes to everybody

Hi Alex,
My name is Paul ,i have probably the last working Cadillac NC100 with GN5 control .
I have taught myself to maintain this unit as it is accurate and i am a small one man shop .
the only problem i cannot figure out is why the optional stop does not work ,the button is wired and i checked the bulb in the push button switch.
but it has only one effect on the program ,when i put M01 in the program it will freeze at that line with the cycle start lamp lit.
pushing reset turns off the lamp
but it freezes with the m01 switch on or off
m00 works as intended as does m02 and m30
any thoughts
Thank you
Paul

[Paul Pippenger]

GN5 has address buttons that allow me to see parameters and diagnostic inputs and outputs .
None of my manuals list a parameter or diagnostic input -output for an M01.
I don't have the original lathe manual,just the control manuals,
I carefully watched the relays at the bottom of the cabinet trying to discern which may have to do with
the M01 function
I run a short program including the M01 and relays come on when it gets to the M01 line but just freezes.
apologies if I am not explaining this well enough, I am hoping you can guide me to some way to solve this.
I will double check all inputs and outputs to see if i get any action when pushing the M01 button.
Peace
Paul
