Parameters for Märklin® high performance
motor
The 5-pole high performance motor from Märklin®
(series 37xxx) is well suited for the LokSound decoder
when programmed as follows:
CV 54 = about 20 – 25
CV 55 = 38
5.2.2 Speed Curve
LokSound decoders recognize 256 internal speed
steps. They may be adapted to the characteristics of
each engine and assigned to the available speed steps
(14, 28 or 128). NMRA allows two choices:
Speed curve via CV 2, 5 and 6 (figure 11).

Set the starting voltage in CV 2 and the maximum
speed with CV 5. CV 6 represents the medium speed.
You may define the shape of the curve (straight or
with two different gradients). This mode is activated
via CV 29 (see Chapter 7.1).

Speed Curve
You may also define an individual speed curve:
Store the speed curve values in CVs 67 to 94 (as per
figure 12). Those 28 values will determine the 256
speed steps. This method permits optimizing the
running performance. This mode is also activated
via CV 29. We recommend the use of the ESU Lok-
Programmer and its software for easy calculation
and programming.
5.2.3 Auxiliary function outputs
LokSound decoders have 4 physical function outputs,
two for directional lighting, two for auxiliary loads.
Additinal 10 functions may be activated by pressing
a button to trigger various sound effects.
If you do not want to use the physical function outputs
AUX 1 and AUX 2 you may control two additinal sound
effects (12 in total).
In addition the functions „sound on / off" and
„acceleration on / off" are available. The latter turns
off the acceleration- and deceleration rate and is
often used for precise control of the engines
particularly while shunting. In „shunting mode" the
speed is halved.
Assignment of function buttons
The outputs may be assigned to the available function
buttons. Each function button is linked to a CV in
which any number of events may be combined. Page
26-27 shows the different possible combinations and
also the ex-factory setting.
Please note:
• Some functions are directional.
• Your DCC command station may not have all
necessary function buttons.
• Each of the function outputs must be turned on or
off separately.
The value that has to be entered into each individual
control-CV is calculated as follows:
Switching on function outputs
Each of the function outputs can / must be turned on,
before it can be used. You may program any of eight
available lighting effects for each output:
