Primary CVs
CV 3
Baseline Acceleration Rate
Description
CV 3 contains a value from 0 to 255 that sets the decoder’s acceleration rate.
D0-D7: Baseline Acceleration Rate
Additional Information
The acceleration rate may be calculated as:
Seconds/Speed Step = CV 3 x 0.896 ÷ Number of Speed Steps
When CV 3 is set to 0, the speed-related sounds will respond almost instantly
to increases in throttle setting, equivalent to no momentum. When set to 255,
it will take the decoder sounds approximately 3.8 minutes to accelerate to full
speed from a standing stop.
It is recommended that CV 3 be set to a non-zero value when operating the
decoder in 14 or 28 speed-step mode, as the throttle will interpolate between
speed steps during acceleration to produce a smoother overall response.
Note: For this CV, the value in a SoundCar decoder should match the value
in a Tsunami-equipped locomotive when in a consist.
Default Value: 0
