Primary CVs
CV 23
Consist Acceleration Rate
Description
CV 23 contains a value from -127 to +127 that corresponds to the decoder’s
consist acceleration offset.
D0-D6: Consist Acceleration Value
SIGN: Sign
0 = Positive value
1 = Negative value
Additional Information
When the consist address is active, the consist acceleration rate is added to
or subtracted from the decoder’s base acceleration rate (CV 3) depending on
the Sign bit (bit 7). The acceleration is then calculated as:
Seconds/Speed Step = (CV 3 + CV 23) x 0.896 ÷ Number of Speed Steps
If the sum of CVs 3 and 23 is a negative value, then the acceleration rate
is set to 0 (i.e., acceleration is instant). If the sum of CVs 3 and 23 exceeds
255, then the acceleration rate is set to the maximum value of 255.
CV 23 has no effect when the consist address (CV 19) is set to 0.
To summarize, a CV 23 value from 0 to 127 will increase the decoder’s base
acceleration rate. Conversely, values from 129 to 255 will decrease the
decoder’s base acceleration rate. A value of 128 is equivalent to a setting of 0
and will have no effect.
Note: When operating Intelligent Consisting, it is best to leave this value at
0 unless all of the locomotives pulling the cars are set up using advanced
consisting.
Default Value: 0
