CVs - Mobile Decoder Configuration Variables -> Momentum CVs-Acceleration CV03 & Deceleration CV04
In the DZ123 mobile decoder, if CV03 and CV04 (acceleration, deceleration) have been programmed for momentum, will momentum remain active when the decoder is then used in analog mode with pure (not pulsed) DC? Yes.
Why do my trains start moving at 25% throttle?You may need to adjust some CV valuesCheck the value of CV02, start voltage; the default setting is 0 (zero). You may need to adjust this value.Check the value of CV03, acceleration rate; the default setting is also 0. It is possible that the locomotive has been set for a slow acceleration rate.You can also adjust how each locomotive responds to throttle inputs by programming loadable speed tables or 3 step speed tables.If you decide to reset the decoder to factory default values , set CV08 to a value of 08 to reset the decoder back ...
Deceleration is the rate at which the decoder decreases from one speed step to the next in response to a new command to decrease speed. CV04, deceleration, lets you simulate locomotive braking action. The range of values for CV04, deceleration, is 000 to 031 (x00 to x1F hex). A value of 00 causes an immediate response to a new command to decrease speed. As you increase the CV value programmed into CV04, the rate of speed step change is approximately 1/10 second per increment in deceleration value. For example a value of 01 programmed to CV04 causes the decoder to change ...
Acceleration is the rate at which the decoder increases from one speed step to the next in response to a new command to increase speed. CV03, acceleration, lets you simulate train weight or inertia. The range of values for acceleration is 000 to 031 (x00 to x1F hex). Setting CV03 to a value of 00 generates an immediate response to a new command to increase speed. As you increase the CV value programmed into CV03, the rate of speed step change is approximately 1/10 second per increment in acceleration value. For example, a value of 01 programmed to CV03 will ...

Whoa!!!!!Each locomotive on your railroad has a mobile decoder which receives the command control signals from the command station and operates the locomotive motor accordingly. The performance of mobile decoders can be adjusted by changing the Configuration Variables (CV's) of the decoder. You can improve the speed performance of a locomotive by adjusting its start speed (CV02, V-Start), its mid-range speed (CV06, V-Mid) and its top speed (CV05 - V-Max). You can also adjust the acceleration (CV03) and the deceleration (CV04).If the deceleration CV value you set for a particular loco is very large, this can make it look like ...
How do I get all the engines of a consist to run at the same speed? I have 3 engines with DH163A0 decoders and one with a MRC sound decoder. All units have the same top speed, but the unit with the MRC decoder starts and accelerates more quickly. Getting a group of locomotives to operate at the same speed can be a challenge. Experience has proven that it is best to work with the slowest locomotive and bring the other locomotives into agreement with that engine. Since the others appear to be in general agreement, it would be the ...
