Risto,
"how can I get into detail what I can expect to happen in real life with an acceleration mentioned?"
A practical approach would be to look at similar machines by vendors and individuals and see what they are using.
Make note of the sizes, weights, axis or drive chains, and speeds provided and also what they doing with the machines.
Use your computer program and compare its output to what others are using that works in real life.
I am not familar with servo's or the program you mentioned but have used other programs for steppers. The programs provide general paramters as input guides. So you can be conservative on those parameters. Now they usualy ask for additional loads you expect and only you can provide those. These values can certainly have an influence on sizing.
So play around with the computer program and see what it tells you. The sizing software may use some inertia guideline ,like a ratio of 10:1 of calculated to actual motor inertia, and often these are general guidelines / rules of thumb which they have found to be applicanle over time. It's just one parameter which provides for motor recomendation.
Like the story on computer use goes, "garbage in garbage out".

Think I,m correct in saying, when going around a circle Mach uses the lesser of the either axis velocity for the movement. I know that in some other programs this dosn't happen. I also know that my faster computer will give me
quicker moves around a circle especially at the axis transition points.
Hope this helps

A computer program is a great tool for doing the calc's for a system and usualy provide for motor selction motor options.
