a31ford Posted January 16, 2014 Share Posted January 16, 2014 Thought there might be a simple answer to my question. I'm wondering what the feedback is in the 3 wires of a servo ? Proportional +/- value on the third wire ? Does this so to speak "Sum" to produce an output on + and - to move the servo or what ? My Take is that it's somewhat like a large op-amp.

bobschm Posted January 17, 2014 Share Posted January 17, 2014 Huh? All the servos I've used have power, ground, and control wires. The control is a square wave. The duty cycle of the square wave determines the position of the servo. Check out servocity.com. They have FAQs that explain a lot. Link to comment Share on other sites More sharing options...
