Motor Gripper Constant Servo Noise

I have two of the servo grippers with the mini servos.

When I first power up the EZB the servos make no noise.

After telling the servo to go to a position the servo moves to the position and stops but keeps making a high pitched hum as if the servo is still trying to move. This occurs no matter what position it moves to.

My other servos for example the legs does not do this.

The only way I can make the noise stop is releasing the servo using the horizontal servo control or ez-script.

Is this normal. I do not want to somehow damage the servos.

Any help is appreciated.

I don't have any EZ Robot servos (yet)... I do however have a few different kinds (all analog) that I use on a regular basis.... In my experience all servos buzz when holding position... some more some less, but they all do...

This was very helpful. Thank you.

Thanks for all the help.

It makes perfect sense to me that the servo would make noise if it's trying to hold something in a position.

What still does not make sense to me is that if I have two servos.

The shaft of neither servo is tied to anything.

One servo keeps making noise as if its trying to hold something in position and the other does not.

That being said it sounds to me based on the responses that this is a not unexpected.

Thanks
