Cannot get the Parallex Standard servo to work

king.oslo

Hello there,

I am working with this servo: http://www.jameco.com/Jameco/Products/ProdDS/283021%20Manual.pdf

I understand, that to get the servo to hold a center position, you send pulses of 5VDC with 1.5ms duration at 20ms intervals.

What are the specs of the signal to get the servo to turn to extreme right, and left positions?

Thank you.

Kind regards,
Marius

The normal settings would be 1.0ms for one extreme and 2.0ms for the other. Each servo has physical stops inside which determine to extreme positions. You can experiment and vary the end pulse width for the particular servo to determine where the physical stops are.

This code is from the link you provided. Center servo pulsout value=750, stock extremes are 500 and 1000.

I had success with .4ms and 2.2ms with 20ms between pulses.M
