NMRA CV 4 - Deceleration Rate

Determines the decoder's deceleration rate.

The formula for the acceleration rate shall be equal to the contents of CV 4 multiplied by 0.896, then divided by the number of speed steps in use. (CV4*.896)/(126). For example, if the contents of CV 4 = 2, then the acceleration is 0.064 sec/step for a decoder currently using 28 speed steps.

If CV 4 equals "0" then there is no programmed momentum during acceleration. Changes in speed will be visibly instantaneous.

NOTE: If your TCS decoder supports the Momentum Modes Feature, this CV can and will be temporarily overwritten with a value based on your current momentum mode.
