Primary CVs

CV 24
Consist Deceleration Rate

Description

CV 24 contains a value from -127 to +127, which corresponds to the

decoder’s consist deceleration offset.

D0-D6:

Consist Deceleration Value

SIGN:

0 = Positive value

1 = Negative value

Additional Information

When the consist address is active, the consist deceleration rate is added to

or subtracted from the decoder’s baseline deceleration rate (CV 4) depending

on the Sign bit (bit 7). The deceleration rate is then calculated as:

Seconds/Speed Step = (CV 4 + CV 24) x 0.896 ÷ Number of Speed Steps

If the sum of CVs 4 and 24 is negative, then the deceleration rate is set to 0

(i.e., braking is instant). If the sum of CVs 4 and 24 exceeds 255, then the

deceleration rate is set to the maximum value of 255.

CV 24 has no effect when the consist address (CV 19) is set to 0.

To summarize, a CV 24 value from 0 to 127 will increase the decoder’s

baseline deceleration rate. Conversely, values from 129 to 255 will decrease

the decoder’s baseline deceleration 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
