Do you know the actual distance between the two pulleys? One thing you can do is apply frictionless support (preferably displacement) so that the belt does not move laterally till it is fully held on two pulleys by only tension in the belt.

I would use a single load step till let us say 60 mm. and then another load step for tensioning the belt from here. You need to play with the number of substeps in these two load steps. Once the two load steps converge well, then you can remove (deactivate) the displacement applied on one lateral wall of the belt in the third load step, and in the fourth possibly apply either moment or rotational acceleration to the driving pulley. I do not understand the reason to apply both, can you explain that?
