Digitrax LocoMotion
®
System
Your locomotives look like the real thing, now you can make them run like the
real thing, too. Digitrax decoders incorporate torque compensation for smooth
as silk operation. You can also program CVs that control momentum, 3 step
and 128 step speed tables, switching speed, normal direction of travel,
scaleable speed stabilization and more to take full advantage of the Digitrax
LocoMotion™ System.
Momentum-CV03 & CV04
Momentum is part of the LocoMotion
®
System. Acceleration is controlled by
CV03 and deceleration by CV04. Both come from the factory set to 000. A
range of 000 to 031 is available for both accel and decel. We recommend that
you try CV03:003 and CV04:000 as a starting point for experimenting with
momentum.
Speed Tables-How the Loco Responds to the Throttle
With Digitrax LocoMotion
®
, there are two types of speed tables: 3 Step Tables
and High Resolution 28 Step Tables. Please see your Digitrax Decoder Manual
for a discussion of the 28 Step Tables. The 3 Step Tables are set up by program-
ming 3 CVs: Start Voltage (CV02), Mid point Voltage (CV06) and Max Voltage
(CV05). These values are set at 000 at the factory. All have a range of values
from 000 to 255. We recommend the following CV values as a starting point for
experimenting with speed tables.
