With Digitrax LocoMotion, there are two types of speed tables: 3 Step Tables
and High Resolution 28 Step Tables. Please see your Decoder Manual for a dis-
cussion of the 28 Step Tables. The 3 Step Tables are set up by programming 3
CVs: Start Voltage (CV02), Mid point Voltage (CV06) and Max Voltage
(CV05). These values are set at 000/x00 at the factory. All have a range of val-
ues from 000/x00 to 255/xFF. We recommend the following CV values as a
starting point for experimenting with speed tables.

Switching speed
is controlled by CV54. The factory setting is 000/x00 for
OFF. To turn on the switching speed feature, program CV54 to a value of
001/x01. 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
for additional information on the settings for CV29.
Scaleable Speed Stabilization
intensity, or droop, is controlled by CV57. The
factory setting for this feature is 006/x06 which is suitable for most locos. You
can adjust this value in the range of 000/x00 for OFF to 015/x0F for the maxi-
mum effect. Consult your Digitrax Decoder Manual for info about CVs 55 &
56 and their effects on scaleable speed stabilization.

The factory settings in the decoder provide silent, smooth operation of your
locomotive under most conditions. For more information about these settings,
please see the Digitrax Decoder Manual or our web site.
