'Fanuc 15 M - Starting problem'

raja (202.156.12.245) -

We have a SEKI milling machine with Fanuc 15 M Control. When we power on, the monitor display shows few pages of memory checking and then hangs on with page heading F15 M14 AT12F / Ram parity (BASE0). Can anybody give cause of this problem and how to rectify this problem ? This machine maker is Seki Iron Works, Japan. Can anybody give the contact information for this company ?

"specific procedures"

This typically means that you have to clear the memory and reinstall all your data. This will typically come up into the IPL menu and display the alarm so I may be off on exactly what to fix. Hopefully you have a backup of everything. Programs, parameters, counters, timers, keeprelays etc.

Is this a model A or B PMC? If model A then your ladder and PMC data is burned into Eprom and cannot be deleted. If it is model B then your PMC runs on From and should be backed up before you go any further.

First thing you have to do is clear your memory so power up the machine holding down “-” minus and “.” decimal pressed. This will bring you into the IPL menu. It has been awhile and I do not remember if there is an option to clear the memory at this point. Once the memory has been cleared then it should bring you back to the original choices in the IPL menu. If not then follow the procedure below. Now you have to input all of your data.

The first thing that you have to do is have the option parameters in hexadecimal format. These would be parameters from 9100- about 9147. Then use the following procedure. You also need the number from parameter 9000 this is the number of axis that will have to be entered in at step 4.

1) Power up machine with "-" minus and "." decimal point depressed

2) Key "99" and "Input"

3) Key Password @ each "?" prompt and "input" after each is keyed

4) Key in "3" or whatever # axes in parameter 9100 @ "AXIS" prompt

5) Step through options by number and key new Hexadecimal codes and "input"

option 1=9100, option 2=9101 ect. Just push input if no change is required

6) If "clear files" appears, hit "Y" - will erase programs etc.

7) When 1st menu appears, key "6" and "enter"

Passwords for the 15 series:

23678625

37264699

19261161

The passwords will not appear when typing them in. Let me know if these passwords do not work. I think the Eastern controls are different.

Best of luck,

Stevo

"Fanuc 15 M - Starting problem"

I agree with Stevo1 from USA,

I think you must be check all cnc board before enter to IPL mode.

few years ago i had same problem, first clear and initialitation but machine run only 3-5 hours and same alarm appeared.

Finaly replace for Base 0 card, until now machine in running.

I have a Fanuc 15-M and have replaced the main-C board. Now it comes up with RAM parity error. I went to reset and got tp the IPL screen now I can't get past it. When I try and dump memory it wants addresses. Any help would be great

"follow above procedure"

Erich,

Follow the procedure that I posted above under Comment#1. Make sure that you have a backup of everything.
