Getting three errors and cant figure them out

y51 Parameter Error, 14 x
z56 Ram Initialize 98033045
M01 Operation Error 0101

I recognize the last as no mode, but the others are not in my books and the literature I have seen on line.

Its a knee mill with 3 axis control.
The machine has been sitting for years and its time to deal with it one way or another.
The display fires and I can move through the screens and get it talking in English (the battery is probably dead)
It seems to have reverted to its default parameters.

Do I simply need reset the parameters, or do I have a bigger issue.
