Cam longer then master modulo

The following axis is cammed to the virtual master with cam 1. Cam 2 is appended to cam 1 at the end of cam 1. When my cam 1 is longer then the modulo of the virtual master, I experienced that cam 1 is not finished to its end when cam 2 is appended. I have the impression cam 2 is appended when the modulo length is passed for cam 1 and not at the effective end of cam 1. What can be done about this situation?

Direct synchronization at the end of the cam With the "MC_CamIn.SyncProfileReference" parameter = 5 you change another cam or the current cam with a new scaling at the end of the active cam. The "synchronous" status remains set. For more detailed information on direct synchronization at the end of the cam, refer to section "Direct synchronous setting with "MC_CamIn" at the end of the cam (Page 77)". 5.7.5 Direct synchronous setting with "MC_CamIn" at the end of the cam (S7- 1500T) https://support.industry.siemens.com/cs/de/en/view/109781851 With V16 you have to start the MC_CamIn at the right masterposition and you have to calculate the rigth "sysnchronous position" and using maybe an offset for MC_CamIn. 5.7 Synchronization (S7-1500T)
