MC_BR_RegMarkCapture001 Usage in mark correction for cutting

Dear All,

I need help in using MC_BR_RegMarkCapture001.

Which mode and parameters should be used if I want to use the mark as a trigger and cut offset as the distance between mark and cut of a continuously moving axis with camming to master virtual axis.
Earlier I was using mode as FIRST TRIGGER + INTERVAL, but it gives me large correction values when the cut offset increases heavily. I think I am doing some error in calculation, or mode selection. So i need basic understanding for the same.
Can anyone explain the modes, parameters and calculating reg mark position for the requirement.

Do let me know in any need.

Thanks in advance
