As I mentioned, the variables will vary based on what your machine options are (i.e. spindle speed, HP, etc.) so won't post values here because they would most likely not match your machine.

Any time I have replaced a VFS5 drive, the following variables are the only ones I have had to change. If you use the values for these variables from your old drive, it should work as long as you purchased the correct replacement drive (and the original drive was working with those settings).
GEARIC
GEARIO
GEAROC
GEAROO
VXDENC
VXDENO
VXNUMC
VXNUMO
MORNT
VORNT
X41
X42
X43
X45
X47
X50
X220
ACC
DEC
P1
P2

Sevenoat,
People do not understand that the VFS5 user variables and program are stored on RAM (CMOS memory) that is in a Dallas Real-Time Clock Chip with an INTERNAL battery embedded inside the Chip package.
Once the INTERNAL Battery has gone below the voltage level to maintain the RAM (Memory); the Chip MUST be replaced and then reloaded.
This is normally done by Kollmorgen VFS5 drive technicians that will also clean the drive, replace fans, replace bad capacitors.
These batteries have a life span of less then 10 years at best. Your machine is much older than that.
If it has NOT been repaired by people with Kollmorgen knowledge and expertise; then it probably will lose or corrupt anything that is manually
programmed into it until it is properly repaired.
