Digital Sound Decoder Technical Reference 7
CV 3
BASELINE
ACCELERATION
RATE
Description
Contains a value between 0 and 255 (0 - 0xFF) that sets the decoder’s acceleration rate:
bit 7 bit 0
D7 D6 D5 D4 D3 D2 D1 D0
D0-D7: Baseline Acceleration Rate
Acceleration rate may be computed as:
seconds/speed step = ———————————
When this CV is set to 0, the locomotive speed will respond nearly instantly to increases in the
throttle setting. When set to 255, it will take approximately 3.8 minutes to accelerate to full speed
from a standing stop.
It is recommended that this CV be set to a nonzero value when operating the DSD in 14 or 28
speed step modes as the throttle will interpolate between speed steps during acceleration to
produce a smoother overall response. The Dynamic Digital Exhaust sound effect will also be
more prevalent with higher acceleration settings.
Default value: 0
