Do we loose the parameters if the battery goes dead on OSP5000L? If yes, how can we re-enter the parameters after replacing the battery?

having never worked with or seen electrical schematics for the OSP5000L, I'm not sure if you will lose any data.

However, the general case is that button batteries are used to keep the internal memory and system clock going in things like computers, etc. I have found that when this battery dies, the expected behavior is loss of user configured data not stored in NVRAM (like a camera memory card but mounted in chip) as well as system time. Sometimes there is a capacitor for holding memory while the battery is replaced, but it's run time is very low relative to the battery.

My advice is to replace the battery ASAP and see if your parameters are still there.

Do not shut the control off until after you replace the batteries. You should be OK.

From Memory (a very leaky memory at times!) you can replace the battery without turning off the main power.

On our Seimens 840, if you shut off the control with a dead battery you WILL lose everything and it is a RPITA to reload.

Yes I agree leave control power on and change battery. If you power down while battery is out or dead you will need to down load or manually reprogram lost parameters. Cheers Dave

mohammadali ,

Be Carefull!! You can lose Data that the battery is there to Keep!!

The Battery is there to backup some type of Memory, by holding the small amount of current needed to keep the data stored as the right sequence of ones and zeros.

DO NOT TURN OFF THE POWER TO THIS MACHINE UNTIL YOU HAVE REPLACED THE BATTERIES.

You can Immediately replace the Batteries But Do Not turn off the Machine!!

If the batteries are dead and you turn off the Machine you will lose whatever memory the Batteries were keeping!!

If this has happened then...

Find your Local Okuma Dealer, or a Qualified Service Engineer, Service Company. (With the Dumbsizing/Downsizing going on, there are plenty of people to call).

When you call, have your Machine Model Name, Serial Number, Control Model AND serial number AND Revision level. If you have Manuals let them know the Numbers from the manuals, if you have the data sheets that are usually kept in the Main Control cabinet be prepared make two copies to save somewhere, If your copy machine can scan and e-mail... send a copy to yourself...

If you don not have manuals (Maintenance, Service, Programming, ask them to Quote them now before the service call, BUY them... Having a CNC Machine without the Manuals is like having a Machine shop without Measuring equipment!!

When the Tech comes ... after he fixes things, and gives you a backUp.
PAY HIM to SHOW you How to make a backup according to the manual... Do it together step by step, Then have him show you how to Load it SAME WAY step by step, Especially at this point take notes and ask questions, pay attention to details!!!

In todays world any lost machine tool time is IRRECOVERABLE without a Time Machine.

Before you have the opportunity to repeat this event, please check your other machines for manuals, Be sure everyone knows where the Low Battery Alarm is indicated on the Controller. The Maintenance Manuals usually give a schedule to replace the batteries, this is usually at Half of the life expectancy of the battery, that is when you should order the batteries, When you get them, get out your manual, Backup your machine and save the file by machine, Serial #, and Date of back up. Then read the battery change instruction and change the batteries!!.

Hopefully your machine came with a floppy to put par. back in if not you should back up all your machines

The battery should be in a little case on the rack. Take the battery out and take the case apart. Digi key has the battery. Some OSP controls will loose data, some won't. Problem is, if it is the one that will loose memory, it's not just parameters. You will need to re-load the system software. No big deal if you still have the floppy disks, but if you don't have the floppy drive, your dealer will have to come out with the external floppy set-up.

Thanks for the info but would you no the # of the battery ? Digi Key Can"t
find it with out the right Part # an I have not taken out the dead battery yet. so not able to see if it has a # on it.
Thanks alot.

the # of the battery
It's a problem, if You try to order by phone refering to Okuma OSP model. Ask any electrician to inspect Your battery. Do not swich off the control. Generally, there are to "AA" a.k.a. R6 batteries connected. Can be something different - it depends. It's easy to check. Then You go to RadioShack and buy suitable NiCd or NiMH.
You need to check. Li-ion Batteries can be used also. If Your electrician is smart enough, he can replace with better modern batteries. Button type, for instance.

Don't know the part number, you need to get the battery out of the case first and look at it. Probably a 3 volt lithium, or two of them. By the time your done messing around, whats a hundred bucks for an Okuma one anyway. They last for years.

Hello. I can tell you right now that if you dont have backups made dont even think of messing with this memory battery until you make some. I used to be a service engineer and Okuma is one of the machines i worked on. Yes you leave power on but you cant pull the board from the rack just because the power is on either, this will be the same as powering down the machine. The battery should be easy to get to. The thing about making the backups is that you will have to reboot the control in install mode to do this and when you do there wont be anything to back up especially on a 5000 control. If you dont have backups then before you do anything, get a pad of paper and pen and go thru every page on the control and right down ALL parameters. After you change the battery you will have to reset the battery data in the control. Reloading the software on a 5000 isn't really hard but it can be tricky and you need to be precise in what you do. In a nut shell you may not run into all of this but if you loose memory and you dont have backups or a written hard copy your life will become hell right quick. It is not just a matter of manually inputting parameters. If you ever get bitten by this once, trust me you won't do it again. Hope this helps, let us know.
