Hi fellow model railroaders,
This might be a really stupid question but, I wanted to ask if someone could explain some of the locomotive settings that are changeable in the locomotive menu:
1. Acceleration delay
2. Braking delay
3. Speed levels
The reason I am asking, I have a Roco locomotive running in DCC and I have found that the stopping distance is so long (compared to the Marklin locomotives). I played around with the above setting but haven’t found much difference.
When adjusting these settings, does it need to be on the programming track? Maybe that’s why I never saw a difference?
If I could get an explanation of the settings then that would be a good start. |

Hi Eddie The CS3 with mSD3 or mSD2 deocder allow adjusting all these parameters easily. Unfortunately, Roco uses a different type of decoder. It may be a Lenz (not sure here) which may be DCC with railcom (Bi-directional comms like Märklin's MFX) If this is indeed a Lenz decoder, I recommend you to visit this web site https://www.lenz-elektronik.de/info/downloads.phpNot being sure about the decoder you have and using only Märklin mSD3 decoders, that is all I can say Sorry Cheers Jean |

Roco decoders are Zimo dcc, with railcom. You need to use the programming track ona cs3 to adjust parameters and cv values. Not all are adjustable. Address is for sure. The Zimo decoders are longer in braking distance, which is more prototypical, and also accel. delay time. They are better too for speed control up and down grades both not under and under train loads.
My Roco 78749 was maxed up on voliume from factory. The acc./brake delays were fine as well, so I didn't try to change. I don't mess with cv's thgat I don't know how will affect the motor, etc. so i didn't try to change any.

Acceleration delay is the time the loco takes to come up to the set speed. Braking delay is the time the loco takes to come to a full stop. The higher the number the longer the time. Speed levels I am not sure of but I think are maximum speed of the loco. All those can be changed on Marklin locos w/o their being on the programming track. Can't tell you about non-Marklin locos or non-Marklin decoders.

I might have to keep it the way it is I think. |

I might try changing to the acc & brake delays while on the program track and test it… other than that I’m not going to touch anything else. |

Zimo user manuals are in German and English on their site.

AIUI there are two braking and acceleration delays: Those that are set in the decoder and handled by the decoder, and those there are set in and handled by the CS3. When the delay set in the CS3 is shorter than that set in the loco decoder, you will still get the full decoder delay. To reduce those, use CVs 3 and 4 of the decoder. With a short delay set in the decoder, you can still set a longer delay in the CS3. Note that doing so will prevent the sound of squealing brakes being heard with many locos. |

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time. |

How to set the braking and acceleration delay in the decoder? What is the difference between the two sets of delays in decoder and CS3?
