HELP NEEDED - How to synchronize table movement on Fanuc 160i-M

[Larglam]

Hi,
I've been looking around for a way to set the two tables of our CNC mill to work as one (we have a really large wood panel to machine).
What I've been told needs to be done is set the V-axis to take the Y-axis commands as is own too, so they'll do the same thing at the same time.

The controller is a GE Fanuc 160i-M

the support guy told me other Fanuc models he knows have a switch "table coupling" on the panel itself, but not this one.
The other option he gave me was that there are sub-programs numbered in the 8000-9000 within the machine itself for just that purpose.

I found one, O9002, labeled "ASSE V TRASFORMATO IN Y" (Axis V Transformation in Y, I made sure it was that) but I am puzzled as to how to use this sub-program...
Tried running it alone or within my program, but neither worked for now.
I looked here for posts on this topic and am still looking (a lot of threads, I am working on my keywords...)

Any help on how to synchronize the tables with that controller, or even telling me whether or not I'm on the right path, would be appreciated! thanks

I will have a play with our machine later and try to find a solution for you.

After having a look and a couple tests with the other similar sub-program (ASSE Y TRASFORMATO IN V), it would seem that they only do change the working axis. Y becomes V, or for the other one V becomes Y (which was already the case, reason why I thought I wasn't using it properly), not the master/slave link between thoses two axis I'm looking for.

I'm looking if there is not a way to use thoses sub-progs to do what I want...
