Re: unknown

Just guessing from your clue - maybe it is an electromagnetic anti backlash.
It might have been designed to run both on power and manual. So when machine
was under power (and harder to turn by hand) the nut was under power also.
When machine was on manual mode, the nut was not under power and therefore
much easier to turn by hand. Does that make any sense?

They
