Tip: It is standard to switch over into analogue mode when applying a d.c. voltage at the
rails. In case that the decoder is run in a layout with a braking route based on applying a d.c.
voltage (e.g. Märklin**-braking route), the analogue recognition has to be disactivated (in
CV#29) to ensure that the locomotive reacts as expected on the braking route.
The setting of the negative or positive d.c. voltage is related to the right rail, as seen in the
locomotive´s direction of motion.
Starting-kick 65 0 … 255 (0) = short-time increase of motor
voltage while starting to clear
the breakaway torque.
Example: CV#65 = 6 à The motor voltage while starting is equivalent to the voltage applied
in operation at speed level 6 (of 255). It is reduced immediately to the actually set speed level
with the braking rate defined in CV#4. Thus, when altering the value for CV#4 it may be
necessary to alter CV#65, too.
