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 or damaged. The only place where I found that ROM number was in an EPROM that is in a cartridge that is attached to this system board. Cartridge P/N: A02B-0091-C111. The owner of this machine had bought another cartridge with same P/N from eBay which once installed shows same System Alarm. I already read the contents of both cartridges and they are not the same.
I checked with CookeCNC and they told me that this cartridge usually contains data that is machine specific and only the Machine Tool manufacturer may have it. However, IKEGAI seems to be no longer in business. I wonder if anyone of you guys has this same machine where we could get the EPROMS contents from.
I read both EPROMs using a MiniPro Universal Programmer vrs. 6.60. Chksum for 801 chip was 0x0054 3364. Chksum for 802 chip was 0x0054 7D96 per MiniPro software.
Please, if anybody can help, let me know.
Thanks in advance
