 Features: Switching Speed, Normal 

Direction of Travel & Scalable Speed Stabilization  

(Back EMF) Features

Switching speed 

is controlled by CV54. The factory setting is 000 for OFF. To 

turn on the switching speed feature, program CV54 to a value of 001. When this 
feature is on, use F6 to activate and deactivate switching speed. With the feature 
on the throttle’s target speed is effectively reduced by about 50% and the effects 
of accel and decel programmed into the decoder are reduced by 1/4. This is useful 

for yard switching operations. 

 

 

Normal Direction of Travel

 is controlled by CV29. See your decoder manual 

or the Digitrax Toolbox App for additional information on the settings for CV29.
