Okay, so I have this servo:
Futaaba S9452 High-Torque High-Speed
It’s a digital servo.
Here are the specs:
4.8V 102 oz-in (7.4 kg-cm) 0.13 sec/60°
6.0V 128 oz-in (9.2 kg-cm) 0.11 sec/60°
When turning the motor without power, I can rotate a bit over 180 degrees.
I’m trying to sweep the servo from 0 to 180 degrees as fast as possible.
So here’s the problem… sweep is slow. Real slow. I futzed with settings and I’m getting no consistent results.
Half the time I can’t even get it rotating 90 degrees… then sometimes it seems to be “oversteering” and bouncing back a bit from the overturn… I don’t get it.
I would think I could get the servo to go to 180 degrees in 0.39 seconds… but it won’t even go 180 degrees at all, and when it gets close, it’s nowhere near that fast.
I’ve tried various examples with all sorts of mixed results but I’m left just as lost as when I started.
