Re-adjustment strength (CV62)
An example will explain this matter best: The motor voltage is insufficient to keep the speed as the load
increases. The PI-load control kicks in and regulates (increases) the motor voltage accordingly to make sure
the locomotive continues with the same speed. The re-adjustment strength is the maximum allowable voltage to
achieve the required speed. The selectable value range is 0…255. The basic setting is “255”, the maximum
strength. This means the eMOTION XLS Sound Decoder is allowed to increase the motor voltage up to the
track voltage if so required. If you lower this value you set a ceiling for the motor voltage which must not 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.
3.8.1. Special driving functions
Switching speed
The maximum speed is reduced by half to facilitate a more effective driving characteristic during switching. 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 basic 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 basic setting is “7”.
Automatic Braking
(since V1.3)
There are two methods to stop a train in front of a stop signal automatically. The first method uses DCC brake
signals produced by a booster with a breaking 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
Programming a pausing time in a simple shuttle operation in analog and digital mode with stopping times can
be achieved. With CV58=0 this function is deactivated, values between 1 and 255 define a waiting time in 1 to
255 seconds. 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.
3.9.Analog mode
In analog mode the eMOTION XLS Sound Decoder is fully functional with as little as 5V track voltage. The
operation in analog mode may be de-activated with CV29–Bit2. The eMOTION XLS Sound 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.
