of the LD-W-11 can be altered by programming the decoder
accordingly.
Load control
The locomotive decoder LD-G-11 for DC motors has a load control, the
decoder LD-W-11 for AC motors does not require this function. The load
control influences the motor voltage to keep the locomotive at constant
velocity, independent of additional loads (e.g. running up a gradient,
coupled carriages).
The decoder chooses automatically the optimal values of the load
control´s parameters for the connected (DC) motor. The range of
values from which the decoder chooses the optimal value can be
altered by programming the decoder accordingly.
Direction of motion
When changing the direction in digital operation the existing direction is
saved and so retained, even if the central unit does not send absolute
driving data (e.g. in Motorola I format).
In order to change the direction of travel in analogue operation a
voltage impulse is applied to the rails which is distinctly higher than the
normal driving voltage. Disturbances from the locomotive motor,
tolerances in the connected components or voltage drops in the rails
can release unintended changes of direction or hinder intended changes
of direction. The voltage needed for a change of direction can be
adjusted by programming the decoder accordingly.
