Motor Control
11.1.2.4. Parameter “K slow”
Together with the LokPilot V4.0 decoder an additional CV 52 has
been introduced which separately determines the gain control
considerably for the whole slow driving sector in speed step 1.
If you are not satisfied with the driving behaviour when the lo-
comotive drives slowly or starts, while everything is fine with the
medium and high speed steps, you should increase the value of
CV 52 by ca. 5 - 10 than the value set in CV 54.
11.1.2.5. Parameter „I slow“
Here you can adjust the inertia of the motor separately for slow
speeds and starting from a stop. The desired value is to be en-
tered into CV 51. The parameters “K slow” and “I slow” jointly
influence the behaviour at speed steps 1 and 2 while the param-
eters CV 54 (“K) and CV 55 (“I”) are responsible for the remain-
ing speed steps. The decoder computes a speed curve in order to
avoid any abrupt changes.

Chart with load regulation values for commonly used motors
Figure 25:
Increase the value by 5 starting with the default value for motors
•
with very small or no flywheels.
Reduce the value by 5 starting with the default value for motors
•
with large flywheels.
Test again and repeat this procedure until you arrive at the desired
result.
11.1.2.3. Reference voltage
In CV 53, you set the EMF reference voltage generated by the
motor at maximum revs. This parameter may have to be adapted
subject to the track voltage and the efficiency of the motor.
If the locomotive reaches maximum speed when the throttle is
set to about three-quarter and the top third of the throttle has
no influence on the speed, then you should reduce the value of
CV 53. Reduce the value by 5 – 8 and test the locomotive again.
Repeat this process until the locomotive just reaches its maximum
speed when the throttle is fully open.
On the other hand, if the locomotive moves too slowly at full
throttle then you should increase the value of CV 53 step by step
until the maximum speed is reached.
