Need Help!- Parameter lost in Wasino CM-3 with Fanuc OM

[microinv]

Hello, I am new to this community, please help me out here.
I work in a university. We have a CNC mill, 1989-Wasino CM-3 using Fanuc OM controller. It has been a reliable machine for many years. Because the machine is quite old, we can only input code manually. This is not a problem for student who is learning basic CNC concept. Recently a group of student needed to input a long code by RS-232 for their project and they tried to find out how. During the process we accidently disconnect the battery which supplies the machine RAM. Now we totally lose the machine parameter without backup.
Because the machine was taken care and handed over by several people in the pass. We have losted the machine manual and all neccessary document sincluding the controller manual, now I don't know how to fix this problem. I wonder if anyone does have Wasino cm-3 or similar model.I search from many resource and notice that the Wasino WMC-3 has similar configuration, but I am not sure about that. If anyone can guild us how to get these parameters back, we'll be appriciated as we desperately need it back for the class.
Thank you very much

With the assistance from Wasino, I finally have the parameters back and I just put them in.
Thank you for all visitor coming to see this post.

Welcome to the group. I am glad that you got the machine running again.

Did you load the parameters via RS232 or by hand? If you have the machine communicating via RS232 so you can load the long code then make a backup of everything on the control just in case this happens again.

Also attached is the procedure for the Oseries and the pinout for the cable.

Good luck,
Stevo

Thank you Stevo, I input the parameter manually. That wasn't a problem since they are not so many. Also Wasino sent me in a form of photocopy too.
Anyway after input the parameter, the machine limits were misplace. I was told to zero it out. However there was a problem on z axis. It moved passing the home position and hit the second limit switch ( the last one that prevents the ram crash to the end of column). After that I can't make machine to move even on the O.T.Release mode.
I've posted this problem in another thread. I hope someone can help me out on this too.
My machine is now able to comunicate through RS232. But every time we loaded the program, after PC show 'transmission successful', the CNC monitor keep showing 'INPUT' and stuck there until we unplugged the cable. Then the program was loaded. So basically it works, only that we have to unplug the cable everytime after the loading process. It was not covenient but I can live with that.
Anyway, thank you again for your help and the information you gave us.

Pao,
As to the RS232 problem try putting a % symbol at the end of the program after the M30.

When you press and hold the OT release button everything comes back on but you can’t move the Z. Typically you can only move in the JOG mode or the Handwheel. I have had machines were you can’t move in JOG. Only in Handwheel. If you still can’t get the machine to move with the Handwheel then you may have to manually turn the ball screw off of the switch then the alarm should clear.

Once you get this working what you will probably have to do is reset your soft overtravel limits so it can not travel to the switch.

Pao,

You’re more than welcome for the help.

What was the fix to the problem? It’s good to post the results so if anyone comes across the same issue and reads this thread they have ideas to try.

I have very old CNC Punching machine
it is AMADA PEGA 244 with CNC Fanuc O4P-C
I Have 2 Problems

1st

the problem was that in start up in cnc mode it give message Power off Start Again when i select MMC mode it show 3 alarms

1- Alarm 100 parameter write Enable
2- Alarm 417 servo Alarm x Axis parameter
3- Alarm 427 servo Alarm Y Axis Parameter
I entered to parameter list i find most of it zeros . I haven't the parameter list of the machine . also when i press on MDI push bottom it is not active . i want the procedure to change the parameters.

2nd

while one of my friends want to help me to fix the problem he remove the battery while the power was OFF . after that when switch the power on again we find in CNC mode new message '' SYSTEM ERRO''. and in MMC mode the page of alarms and parameter not come it stop after checking memory then i couldn't even go to parameter pages now .

i need help from my friends here to fix all this problems .


best regards
