Speed Curve; Changing Between Operating Modes; Changing From Digital To Analogue Dc - Esu LokPilot V4.0 Instruction Manual

Adapting the Driving Characteristics
The M4 capable decoders do not implement the 3-point line as
per the NMRA standards. Instead only the start voltage (CV 2) and
the maximum speed (CV 5) are supported. You will find more info
on this in chapter 10.3.

You may also define your own speed curve: simply enter the de-
sired values in the CVs 67 to 94 (also refer to Fig. 23). The decoder
will superimpose these 28 values onto the real speed steps. Thus,
you can adapt the driving performance optimally to your locomo-
tive. This mode is only active if bit 4 in CV 29 is set.
We recommend using the ESU LokProgrammer for easy and com-
fortable programming.
When this mode is active, the settings in CV 2, CV 5, and CV 6
have no influence.

LokPilot XL V4.0
LokPilot V4.0 M4 and LokPilot XL V4.0 implement the concept of
the mfx® speed curve. That means that the speed curve is always
active and cannot be turned off with CV 29 bit 4. CV 2 and CV 5
define a scale factor around which the points of the speed curve
are scaled. This ways it is far easier to adjust the maximum speed
of a locomotive to an active speed curve.
Have a look at the speed curve in Fig. 24. The last entry (CV 94) is
255. This represents full speed. If you wish to reduce the maximum
speed you only have to reduce the value of CV 5. The decoder
computes (squeezes) the speed curve in such a way that the shape
of the speed curve remains despite the lower maximum speed.
The same is true for the first entry. The speed curve will be raised
and scaled subject to the value in CV 2.
The CVs 67 and 94 are permanently set to the values of 1 respec-
tively 255 in this decoder.

10.4. Changing between operating modes

You may change from a digital to an analogue sector of your lay-
out „on-the-fly" at any time.
The locomotive behaves as follows:

10.4.1. Changing from Digital to Analogue DC

When the decoder enters the analogue DC sector, it monitors the
polarity of the track voltage. If the polarity (and the resulting direc-
tion of travel as per NEM) matches the the direction of travel in
digital mode the locomotive will continue without stopping at the
speed that corresponds to the analogue voltage.
If the polarity does not match than the behaviour depends on the
settings in CV 27:
