Locomotive decoder LE230
DIGITAL plus
The configuration variables and their meaning
The new line of Lenz advanced decoders, version 5.1, support a
full range of features which are set up using a variety of
configuration variables. All the configuration variables are
numbered. These numbers are used during programming and
are identical for all decoders that conform to the NMRA
standards independent of the manufacturer. The following table
lists the various CVs supported in the LE230 decoder. Both the
New CV numbers and the older Register numbers are provided
for cross reference.
Please note: Some CVs (such as CV29) have specific meanings
for each bit. The bit assignments in this table use a bit
numbering scheme of 1-8 to correspond to the 1-8 display on
DIGITAL plus systems. Many other systems use a scheme of 0-
7 to refer to the individual bits. If you are using such a system
you should subtract one from all bit numbers described in these
CVs.

This is the number with which you select a locomotive in
the DIGITAL plus system.

Start voltage:
This is the voltage applied to the motor in speed step 1.
Set this value so that the locomotive just starts moving in
speed step 1.

Acceleration Momentum:
Determines the rate of change of speed upon acceleration.
A higher value leads to a slower acceleration.

Brake Momentum:
Determines the rate of change of speed upon braking. A
higher value leads to longer brake distance.

Maximum speed
Determines the maximum speed that the locomotive will
move. This allows you to operate your locomotives in a
prototypical speed range.
