Dear Alex, If you check the manual, under the 'optimize' command you will find all the default values for each possible parameter. That is how modeller runs by default. If you do not like the default values , you can change any of them as you wish.

there are 5 pre set optimization protocols 'refine_1' 'refine_2' ..'refine_5' . The higher the number the more extensive the MD simulation. As a first approach you could play with these, without setting every param individually.
