Moving a Servo beyond its defined range

[amadcow]

Has anyone noticed how servos are able to move beyond the range defined?  For example, a servo that takes a PWM of 600us to 2400us for 0 to 180o respectively can actually move a little further when given PWM signals slightly above and slightly below that range.

You can also see this when you manually turning the servo.  The range of motion is beyond 180 degrees.  Is it safe to go beyond the specifications of 0-180o in this situation?  And if so, by how much? 

I find that if I give it too high a PWM, it'll hit a stall current type situation because it's being blocked physically.

I also I have noticed that a 180 servo, I can move it around 200 degrees. But I modified my servos for continues rotation.

It is safe to go beyond the 180 degrees. People modify servos to go 360.

Try cutting off the physical stop like you would to modify it for continuos rotation. Then see how far it can go.

The ratings are typically based on how far the receiver can turn the servo.




Using code and an MCU you can push it even further than its rated.
