Re: Need speed switch for DIY funicular/hillside elevator

Jon, I'm not sure.  It currently travels at 1.3 ft/sec up and down and
is set at half speed.  When I get more time (its not my fulltime
residence have to travel 5 hours to work on it) I want to crank up the
speed to near full speed which should be a little over 2 ft/sec.  The
trick is that I have to adjust the start and stop microswitches to keep
it from crashing to the bottom or the top with the increased speed.

So, I would assume 3 ft/sec would be considered the "out of control"
condition.  Since the drum is 12" diameter (3.14 circumference) that
would be about 60 rpm.
