Motion Controller

I am working on a conversion of mechanical horizontal packaging equipment into servo controlled using Q172DCPU and MR J3 series servos. I am having trouble in making the cam data for the end sealer part which has a mechanical eccentric slow down. Maybe somebody here already tried converting it or maybe built a new machine using servo for the end sealing. Please share if you have some idea or some formula/equation that I can refer to in making the Cam data?? Thanks!!
