Integrex C Axis Sync

We have an Integrex 100-IISY with fusion conrol. I am trying to figure out how to bring the sub up and sync the C axis on the main and sub so I can mill with part clamped in the main and sub spindle. I don't want to just let the sub go along for the ride as the parts are a small diameter to drag the sub spindle around.

I have tried
M200 (main milling mode)
G112M200 (sub milling mode)
M511 (sync ) this turns off mill mode and changes to turn mode.

Also M514 does not work.

I am programming EIA not Mazatrol.

I have seen that Matrix has a parameter to change for this but not sure about Fustion 640MT

Thanks for any help
