Motor Control
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 a third 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.
11.1.2.4. Parameter “K slow”
Together with the LokPilot V4.0 decoder an additional CV 52 has
been introduced which seperately 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 locomotive
drives slowly or starts, while everthing 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. Adaptive Regulation Frequency
The decoder operates ex works with a mutable (adaptive) regulation
frequency to drive the motor as precisely as possible. However,
as a result some motors might show a nasty buzzing noise.
For such motors you are able to set the regulation frequency on a
constant value. Set bit 4 to “1” in CV 124.
