Bios version of Yasnac LX1 control CP-04 corrupted memory module


Feb 17, 2021
Hi everyone,

I'm looking to fix an issue with a Yasnac LX1 control (SL-1) with a CP-04 Error
#81 05:F9:820.

This can mean that I have a bad #81 chip. I spoke with one echnician that are more familiar with these units. He advised that I can replace the chip but he will need to know the software version that are using on these chips.

There are 8 memories and the BIOS version written there are 03313.02, 03399.03. However, I cannot find this files.

Moreover, one company can send me a set of 8 chips that are for a later version machine (Mori Seiki SL-3). I am not sure that this will work though but it might get me to boot up.

Does anyone have the correct chips for my CNC Yasnac LX1 - Mori Seiki SL-1? I´m willing to pay for

Thanks for your comments.

Right now the machine is not working.
