Scaled Neutral Offset

Scaled Neutral Offset

Scaled Neutral offset is a feature that allows the user to adjust the neutral position of the servo off of its center position and still maintain the full range of servo travel over the full range of transmitter input. For example, a servo normally rotates +/- 45-degrees for full transmitter stick movement, and the neutral offset is adjusted so that the servo is 20-degrees clockwise from its center position when the transmitter stick is sitting at neutral. The servo will move linearly between +20 to +45 degrees when the transmitter stick moves the servo clockwise, and the servo will move linearly from +20 to -45 degrees when the transmitter stick moves the servo counter-clockwise. In this case, the motion is scaled differently depending upon which direction the transmitter stick is moved.

When Scaled Neutral Offset is turned off, the scaling described above is disabled, and the servo position will "saturate" in the same direction as the offset. Using the same example as above with the Scaled Neutral Offset turned off, the servo would move from +20 to +45 degrees when the transmitter stick is moved a little more than half way when the servo moves clockwise, then the servo would stop moving when it reached 45 degrees even though the transmitter stick still has available range. In the other direction, the servo would move from +20 to -25 degrees as the transmitter stick is fully deflected.

Enable or disable Scaled Neutral Offset using the radio-button on the left side of the SM2 Control Panel Application.
