@Eli Grobin: Yaskawa is here defining "pitch" as rev/inch, instead of the (much more common) inch/rev or mm/rev. With this definition, a higher "pitch" does give you a finer thread ball screw. Their definition of pitch was confusing for me also. At 2:28, I was expecting to see the pitch term P in the numerator.

[@YaskawaAmerica]

It is possible that he is referring to ball screw lead instead of pitch. The friction torque units appear correct in LBFF-in. Here is more information on lead versus pitch.

When you reference the change in pitch around 6:50, what are the units of pitch? Your example references a larger pitch but then shows a finer thread ball screw, and this confuses me. I would think going from pitch of 1.5 mm to pitch of 1.0 mm would decrease the effect of the linear components inertia on the total inertia.

Excuse me Sir, why is the gravitational acceleration included in the rotational inertia equation? min 8:17

[@YaskawaAmerica]

It is all about unit conversion. US Customary Units are implied in this case. Gravitational acceleration is included at 6:30 to convert weight to mass. At 8:17, to be consistent, the assumed units are also weight per cubic volume (for example lb/ft^3). We might have made this more clear by expressing the term as ρ/g. Hope this helps.
