Well? What was the solution?
I'm having same problem on same machine model number. Is it also security switch?
PMC parameters such as data tables (1, 2, 3, etc), PC timers (1 and 2), keep relays, PC counters #2 (PC counters #1 was missing) were entered as well.
Thanks for your input DRDOS. I'll see what I...
How can I do that if I can't go past the "998 ROM Parity alarm" message? Any suggestion I may not know of?
I finally got the parameters list.
Please review.

I was called to load parameters to this machine. They lost them due to neglecting to replace batteries on time. A USB stick with 107 pictures of the different screens with parameters was handed to...
I have already requested the parameter list. I'll post them as soon as I get them.
Thanks
Everytime we start this machine with Reset, same 998 ROM Parity No. 801 Alarm comes up. We cannot go past this point. No way we can re-enter parameters.
However, if anybody has the contents of...
Bumzag and Memoryman,
I have included the pictures of EPROMs inside Macro Cassette. The EPROMs with handwritten labels on are the ones that came in the original Cassette. Whatever could have been...
I'll do as you say. I'll check power supply.
If you have a schematic of starting circuit I will really appreciate it.
You can turn power on with main power switch. Fans start but when you press the start button on operator's panel nothing happens. After a few minutes, you press the start button it chimes and screen...
Just got called to see this machine. It doesn't start when pressing the start button first thing in the morning. After several minutes, it starts as if nothing was wrong. Owner doesn't have...
This is another picture showing the entire area where these EPROMs are.

Memoryman,
Thanks for your reply!
Socket F81 is empty. So is socket FA1 right above it. Sockets FE1 and FC1 between I/O connector and FA1 and F81 seem to contain system software.
Now I am...
I was finally able to go back to machine.

I just got brand new EPROMs to burn the contents of original cassette. I'll let you know what results I get.
If cassette is not in place, we get a Watchdog alarm.
We used to get 911 RAM parity...
I was called to see this machine showing the system alarm 998 ROM Parity: ROM No. 801. The system board P/N: A16B-1010-0281/03A.
According to Fanuc O-T manual, 801 is the ROM that may be corrupted...
Hey Confyone! Did you get it fixed?
I have similar problem.
I stand corrected. I noticed that generaldisarray suggested to do a motor/drive swap after the first posting. You should contact him for more information.

Hi there! I just re-read the entire thread and didn't see anything related to what you're mentioning above.
However, let me tell you that it's been 2 full years since this thread was started and...
Hi there! Good to know that this thread was read by somebody!
Yes, those signals are shown in the schematic. I haven't visited that site since then, but if you can't find the schematic let me know...
Did you get it fixed?

*** PROBLEM SOLVED ***
Given the fact that apparently nobody works with these Fanuc DC Spindle boards anymore, I had no choice but to plunge in into the problem.
I started by checking the...

Yes, we have. However, motor is still good and spindle runs very well as long as we let the spindle drive run when warm. Fuse blowing occurs only when we let machine run cold which happens only when...
This is something that I’ve had happening blowing 2 – 100A input fuses out of 3 at least once every summer during the last 4 years and/or occasionally turning LED 2 on early in the morning when...
Hi Guhl,
If it works with Fanuc 6MB, go ahead, tell me more. I'm all ears.

Bill,
Where did you get that btr board?
I have searched that company and they apparently have no website.
I will really appreciate if you could point me to where that board can be bought.

Well, not having a manual this was tough. In order to make sure the drive was bad and no mechanical load was the problem, we had to remove the motor and tested it this time sitting on a wooden...
Hi there!
Matsuura MC1000 with Fanuc 12 installed.
Problem: It all started a few weeks ago with AC input A 30A fuse blown along with its 1.3A alarm fuse on Y-axis servo. Fuses were...
