I have a Moore Jig Grinder with a 16i-M Fanuc control. We had an “Outer Rom Parity Error (Graphic)” and had the issue fixed by reloading the software from a previous backup.
The problem is that the backup we used to restore was from 1998 (14+ years old). We got the machine running fine but the memory is VERY low. We can’t hold many part programs like we use to be able too. When we get a big program we may not be able to load it at all.
It’s been a long time, but we think this machine had a memory upgrade years ago (around year 2000). It use to have 256k and was upgraded to 0.5M. The problem is that the memory upgrade happened AFTER the backup was created.
When we restored using the old backup we must have lost a parameter or memory setting from the memory upgrade? Can anyone help with this issue?
From what I have found, parameter 9921 sets the amount of memory available? Does anyone know more about the procedure to change this? It is currently set at 01001000
*NOTE: We have an identical Jig Grinder that had a memory upgrade at the same time and has parameter 9921 set to 01000001.
I have already tried to change parameter 9921 to match our other Jig Grinder (01001000 --> 01000001) and it wouldn’t change. An error came up saying it had to be shut off and nothing changed. I must be doing something wrong.
