voltage if so required. Lowering this value sets a ceiling for the motor voltage which cannot be exceeded. This
might meet reality closely as the power reserve of real locomotives is not unlimited. Entering a track segment
with an upgrade the locomotive will be only partially able to cope with the new power demand and will decrease
the speed at some point. With the setting at “128” the readjustment is limited to 50%. In case the locomotive
reaches this limit, a speed decrease will occur under an increased load.
The basic setting of the PI-load control is set to “fast”. This enables fast speed changes but may result in over-
regulating and thus to bucking.
The PI-load control may be switched off in CV49.
3.4.1. Special Driving Functions
Shunting Speed
The maximum speed is reduced by half to facilitate a more effective driving characteristic during shunting. This
feature may be set on any programmable function key. With CV59 = 0 the function is “off”. Values between 1…
16 define the number of the function key. The standard F-key setting is “8”.
Dis-Engageable Acceleration/Deceleration Times
Disabling acceleration value and braking value: the programmed values of CV3 and CV4 may be reduced to a
minimum by a single keystroke. With CV64 = 0 the function is “off”. Values between 1…16 define the number of
the function key. The standard F-key setting is “7”.
Automatic Braking
(V1.3 and up)
There are two methods to stop a train automatically in front of a stop signal. The first method uses DCC brake
signals produced by a booster with a braking module (Broadcast), the second method utilizes a DC signal
(Brake-On-DC). For both methods a track portion in front of the signal must be totally isolated and powered by
the respective signal.
For Brake-On-DC the option for analog operation must be blocked (CV 29, Bit2).
Please check your DCC
system manual for further information.
Pausing Time during Shuttle Operation
You may program a pausing time in a simple shuttle operation in analog and digital mode. Values between 1
and 255 define a waiting time in 1 to 255 seconds, with CV58=0 this function is deactivated. The activated
pausing time is executed only if the driving direction is reversed during operation, e.g. by an analog electronic
shuttle control. In case the locomotive is stopped and started in the same direction, the pausing time will not be
executed.
3.5. Analog Operation
In analog mode the eMOTION XXL Decoder is fully functional with as little as 5Volts of track voltage. The
operation in analog mode may be de-activated with CV29–Bit2. The eMOTION XXL Decoder features an
internal motor characteristic curve which enables a smooth operation by measuring the track voltage. An
analog load control (pat.pend.) may be activated (CV49-Bit2). The 3 light outputs are always activated
according to the driving direction. The 6 function outputs (CV13) may be activated in analog mode also,
including the dimming and flashing features.
