Tips for DCC Motor Control
A
reader requested a column on how to optimize motor
control, so here comes a pretty technical column with-
out a lot of pretty pictures. This subject is scale inde-
pendent. I've used these techniques in all major scales from Z
(1:220) to Fn3 (1:20.3), including N,HO, S, O and G. I'm going
to share some concepts and include some comments about
specific decoders. Remember to read the literature that came
with your decoder and what the manufacturer has online
before you try these adjustments. What specific CVs do may
vary between manufacturers. That's why I only mention NMRA
standard CVs (ones that are common between all manufactur-
ers) in this column.
My goal with DCC is to provide immediate and precise control
of my locomotive. When I crack the throttle, I expect the loco
to start to crawl. Opening the throttle wider, I expect a smooth
transition to running speed. I don't want slot-car style top
speeds. If the decoder includes sound, I expect realistic sound
