S7-1200 and V90 Faults

Hi, I am using v90 to  roll feed metal sheet. I am using sina_pos block and telegram 111

I am getting a few errors.

1. Since I need to feed the sheet for very long time in one direction the encoder of the motor reaches its limit and driver gives the error F7493. Manual reccomends to lower the resolution but if I lower it motor can not feed required size. For example I am using 10000LU = 1mm if I reduce it to 1000LU=1mm it can not feed the correct size. How can I solve this? Is there a virtual encoder option? If there is how can I use it?
2. F7450 standstill monitoring error. standstill window is set to 1000LU(0,1mm)  is right now. It's pretty high already. Can it cause because of something else?
3. F7440 Jerk time is limited. P2572 AND 2573  is set to 120000. And p2574 is set to 84168 . I added a zero and made it 841680 it might solve it but would it cause a problem?
   

First 2 questions are more important for me. And thank you in advance.

Solution: I activated modular axis from mechanics and it solved 7493

For 2 and 3 I increased the dynamic factor from motor optimization tab and optimized again. It is ok now. Now it drives more precise.
