CV 23
Consist Acceleration Rate
Description
Contains a value between -127 to +127 corresponding to the decoder’s
consist acceleration offset:
Bits 0-6: D0-D6, Consist Acceleration value
Bit 7: Sign
0 = positive value
1 = negative value
When the consist address is active, the consist acceleration rate is added to
or subtracted from the decoder’s base acceleration rate depending on the
sign bit. The acceleration is then computed as:
seconds/speed step = (CV 3 + CV 23) x 0.896÷Number of speed steps
If the sum of CV 3 and CV 23 is negative, then the acceleration rate is set to
0 (i.e., acceleration is instant.) If the sum of CV 3 and CV 23 exceeds 255,
then the acceleration rate is set to the maximum value of 255.
This CV has no effect when the consist address is set to 0.
In summary, a CV value between 0 and 127 will increase the decoder’s base
acceleration rate. Values between 128 and 255 will decrease the decoder’s
base acceleration rate.
Default value: 0
