Base and Motion ValueS

Base-Value:

The constant contribution to the output of the Motion-Dimension FB

Motion-Value: (read-only)

The motion contribution to the output of the Motion-Dimension FB - equal to the motion-values at the input-connector.

Base-Value + Motion-Value (Constant + Motion)

Base-Value + Motion-Value = Motion-Dimension at the Rocker or Slider.

Note: Units (angular or linear) are defined by the data-type at the input-connector.

Directions

Negate Motion-Values

◉ Positive Motion-Values : Motion-Value × 1 (default)

◉ Negative Motion-Values : Motion-Value × –1

Negate Base-Values

◉ Positive Base-Value : Base-Value × 1 ( default )

◉ Negative Base-Value - Base-Value × –1
