Linear Braking Distance; Constant Linear Braking Distance; Push-Pull Trains; Braking At Speed Step 0 - Esu LokPilot V4.0 Instruction Manual

Adapting the Driving Characteristics
Via CV253 you can chose how the LokPilot should decelerate.

10.6.1. Linear braking distance

CV253 = 0: The loco starts immediately to stop linearly after receiv-
ing the braking command. The brake effort is determined by the
decoder so that, independent from the starting speed, the loco
will stopp after reaching the way defined in CV254. The dashed
line in Figure 24 shows the relation.

10.6.2. Constant Linear Braking Distance

CV253 > 0: Is the value in CV253 higher than 0, the locomotive
continues to drive ahead for some time when entering the brak-
ing section to finally brake within the braking time indicated in
CV253. The effort of the braking effect is now constant as set in
CV253. The decoder changes the brake timing accordingly so that
the locomotive stopps at the correct position in the end. Figure 24
shows this quite clearly.

10.6.3. Push-pull trains

In order to assure that push-pull trains also stop at the correct
point ahead of a red signal it is possible to set the braking distance
for the reverse direction separately. This can be done with CV 255.
If the value of CV 255 is greater than 0 then the value of CV 254
determines forward movement and CV 255 reverse movement.
Typically the value for the reverse movement (driving trailer leads
the train) is set for a shorter distance.

10.6.4. Braking at speed step 0

In order to apply the constant braking distance mode the decoder
must generally detect a braking section. This may be disadvan-
tageous, particularly when operation is computer controlled be-
cause the software transmits the "braking command" directly by
setting speed step 0 even if there is no physical brake section.
In order to assure that the LokPilot V 4.0 responds to the brake
command with constant braking distance can be achieved by set-
ting bit 7 in CV 27. This results in the decoder braking whenever
speed step 0 is set.

10.7. Settings for analogue operation

You can adjust the acceleration and maximum speed of the LokPi-
lot separately for analogue DC and AC mode. Thus, you can adapt
the speed of your locomotive also to analogue operations.
You will have to determine suitable values by trial and error since
they depend on the type of transformer (throttle) and the drive
system of your locomotive.
Please note that load compensation is always active ex works,
even in analogue mode. This gives you smooth control even at
very low speeds.

10.7.1. DC analogue operation

LokPilot XL V4.0
LokPilot Fx V4.0
In DC analogue mode you can adjust the starting speed with the
CVs 125 and the maximum speed with CV126.
The motor is switched off again as soon as the throttle voltage
goes below a certain value. Normally this value is equal to the
switch on voltage (CV 125) but can be lowered by an "Offset".
This offset is stored in CV 130.
Functions such as lights and sound can be turned on in advance
even when another (usually lower) voltage independent of the
motor. To achieve this, the offset is written into CV 129.
The behaviour can be described as follows:
