RESTORE after RESET DELETE
If you have made a good SRAM backup when the machine was running it is easy and it can be done from bootup screen. Very few people have this
The procedue below is for the whole main board is changed
If you did just a reset and delete then ignore step 2 and do the 4 other steps
i) Power up with reset and delete. It will loose everything
ii) When the machine is regularly powered up it will have all the FANUC files with B1A1 - XX is the version (here 25) and load up. It will have the MM and MC files too( if new board is being put in - It will also have some parameters and some default ladder (.MEM file ) and default macro SO have a
a) backup these 2 files in SRAM card - not needed for just reset and delete. Needed only for new board
b) Parameter files in DISK
c) All the program and subroutine files in Disk
Restore procedure

1) Bring up the machine with reset and delete. The fanuc will go to default RS232C with 4800 7, Even, 2. If you setup your computer to this, it should work. YOU DO NOT HAVE TO CHANGE ANY PARAMETER LIKE 20, 100, 0 or anything. LOAD the PARAMETERS first or else you may not find the READ softkey later. READ KEY DISAPPEARS IF YOU DO A POWER DOWN AGAIN.

2) Bring the machine back in Bootup mode and do “SYSTEM DATA LOADING” with this load both .MC and .MEM file. This loads the LADDER and MACRO files to the FROM module (FANUC FILES ARE LOADED TO THE DRAM- THESE NORMALLY DO NOT GET CORRUPTED)

3) Set pwe = 1 under setting screen

4) Change 3202 NE8 and NE9 = 0
5) Load all the programs including O9200 ad O9999 (options). When loading just watch the number O change but not go into Lib yet . It may mislead you.
