OK Why are there two speed options (50Hz & 60Hz) on my motor settings for 24fps? Isn't 24 = 24 in any math class? You can't change shutter angle by the flip of a switch. Is this only for a pilot tone running OUT to an audio recorder or something to do with powering from an AC source? I always use clapper boards so from what I can see, I could use either setting since they are "identical"??

It must the power supply selection. What camera are you using ?

If you are in US it's 60 Hz, if you are in Europe, it's 50 Hz

It's an Eclair NPR and runs off a battery. So it wouldn't know if I'm filming in Paris or Chicago. As I see it, either setting won't change the motor speed or any internal camera frequency. Both the Perfectone and Bela motors have this setting.

You run on batteries, OK, but the motor could be supplied through the AC current, as well, so I guess this is why (Paris, Texas, wouldn't be the same as Paris France, BTW... ;) )

Probably the pilotone output to Nagra recorder.
