Hi CNC Brothers and Sisters,

I have an older Okuma that runs 1 operation production. The driver board for the ATC is on it's 3rd replacement after biting the dust. There is not an ATC on the machine but we still use it for single operations. I'm an looking for a way to bypass/Disable the ATC so the alarm goes away. I contacted Okuma tech support and being the machine is older there isn't anyone that would know how to go about doing this. I haven't found any options in the manual nor the parameters list.
Please if anyone reading this knows how to fix this I would be truly grateful.
I would also pay $$$ to get this fixed.


Thanks in advanced,

David Oates

Replace any & ALL M6 commands in your NC code with M0 (program stop)

oau, nice, pretty good superman

that's a good point, i wonder why else would there be atc related errors, if machine does only 1 operation ? you are the ( sup er ) m a n

Kitty... read his post
He is "pissed" that too many usless toolchanges have possibly stuffed his driver boards
PLUS...
HIS F#$%N MAGAZINE HAS DECIDED TO GO ON HOLIDAYS.

That model came out as OSP7000M, you may find the screen came from an OSP700 machine ( or its a typo?)

The ATC is no longer on the machine unfortunately. Having to buy these driver boards just so the machine can operate does suck.
So to wrap it up...I don't have a ATC but when the driver board goes I still have to buy another one. Go figure.

[deadlykitten]

worth trying, but unfortunately i can't do it for 700M :
... plc scaning with & without that board then manage the difference by forcing a signal
... disable special function

for replacements/service, try okumaelectronics.com / kindly

ps : superman, i really thought that M6/M0 would be a nice quick fix

Tampa, you would also have to comment any T# as well, as this would try to force motion to the tool magazine (either to toolchange or prepare next tool).

Any M63 must also disappear ( readies an empty pot for emptying the spindle.

ie.
M0 ( T# M6 )
or
( M63 )

Unfortunately I can write programs all day and it still will not get past the alarm. Hence trying to bypass the ATC alarm caused by the driver board.
Also, The ATC is no longer on the machine. :tired:

I understand your issue from the 1st post.
I'm saying you need to eliminate any code that tries to make the magazine come into play ie. the M6, T#, M63 and I think M64
What is the actual error that appears ( entire 2 lines) ?

SVP Error with the driver board. Common problem with this particular. Plus there has been no need for adding M6, M63, or M64 in my programming since the machine is just 1 operation.
Thank you for the idea you had though.
I was just hoping my resolve wouldn't be a costly $$$ one.

You would be looking for a Parameter -Long or Short that can tell the machine ATC not active ------------On Fanuc its a Keep Relay and Most Okumas used to have this option

Ask to Okuma sevice to change ATC spec code.from software.

He has an Electrical / Electronic problem not a code problem, no amount of coding is going to solve this problem, he would have to change it in the machine logic to eliminate the Tool change operation

[OkumaWiz]

It appears that you may be able to "shut it off" by changing the spec code in a few places:
EC spec code:
With ATC =0
With TS axis =0
Without TS-axis drive motor =1
They should be in the spec code file...this is something Okuma normally changes...and still should be able to in spite of what your distributor says.

Kurmay claims to be able to do this. My success has only left me with a "test software" message, but may be able to prove this theory - because I have not tried doing this mind you. Only theory based on experience. The message would be better than the alarm IMHO.

Right now the machine is probably looking for the motors and encoders and will always be until the software spec code is changed.

Best regards,

Hy mr wizard if i may, what have you done so to get that message poped out ?

if spec involves hardware, then is not as easy to diagnose the effect of spec on/off; only method is to hope to achieve longer life than what the previous 3 boards delivered, but longer life may not be caused by spec ... i wonder what lifetime was there for previous boards

another idea is to compare plc map with and without the board, then mask the difference

Or simply rely on service technician to diagnose a failed board, or compare it to another in good condition, so to localize the deffect / kindly

spec off + remove board ? i would try it

[MCR-B II]

spec off + remove board ? i would try it

Yes board and motor

[TampaCNC]

spec off + remove board ? i would try it

How do I achieve turning off the spec? :stickpoke

[deadlykitten]

as 1st recomandation, talk to kurmay

Are we talking about an axis servo control board or the NC control driver ?
