CV 23
CONSIST
ACCELERATION
RATE
Description
Contains a value between -127 to +127 corresponding to the decoder’s consist acceleration
offset:
bit 7 bit 0
sign D6 D5 D4 D3 D2 D1 D0
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 com-
puted as:
seconds/speed step = ———————————
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 (0x7F) will increase the decoder’s base acceleration
rate. Values between 128 (0x80) and 255 (0xFF) will decrease the decoder’s base acceleration
rate.
Default value: 0
