I think your 'Inertia Table load' is incorrect, pitch is defined as the distance the table moves with one turn of the motor (2pi), ignore the gear ratio.

So I took it further and sourced some of the heavy formula's. I didn't go to the fullest, I have added a "default" inertia for motor and reduction for example. But the calculations turned out to be quite interesting and fun to play with so I updated the calc sheet pretty much. Please have a look! Some goes as before, could be totally wrong (At least I tried!). http://bit.ly/16DrFdP /Sven ---------------------------------------------------------------------------- -- Get 100% visibility into Java/.NET code with AppDynamics Lite!
