Conversely, if the locomotive runs seemingly too slow throttle is fully open, then
you should increase the value of CV 53 se stepwise until the maximum speed is
reached.

11.1.2.4. Parameter "K slow"

The CV 52 determines the control gain separately specifically for the whole slow
down in speed step 1. If you are using the driving behavior hold at low speeds or
start still not satisfied, on the other hand at medium and high speed steps
everything fits, you should use the value of CV 52 to 5 - 10 einstel- higher len
than the value in CV 54th

used up to which the defined internal gear 52 in CV gain value in CV 51 is
determined. From the mentioned gear, the decoder calculates a characteristic
curve and increases the gain up to the set in CV 54th

In the CV 56 can be defined as start to operate at reduced speed control. Tends
your engine, especially in the lower movement stages to ruckeligem driving, then
the value in CV 56 should be reduced.

11.1.3. Measuring method of the EMF control

With the LokSound 5 it is now possible to change the EMF measurement as
needed to achieve a better drivability for trial keynote engines. Thus, the
LokSound 5 can control the motor, the motor is turned off at regular intervals and
the measured emf voltage (generator voltage of the motor). The more often this
measurement is done, the more it can be done accu- control. The frequency of
measurement is called the "measurement period".
In addition to the frequency of measuring the length of the single nen measuring
cycle is important. is measured, the longer, the more interference can be, for
example, by Kommutatorbürstenfeuer
negative impact on the quality of the measurement. The length of the
measurement in each measuring period is referred to as "blanking". Fig. 37
illustrates the relationship.

With the help of CV 116, the length of the measurement period can be set for
driving stage 1 in steps of 0.1 milliseconds. The range of values ​ ​ f rom 50 to 200
thus enables measurement periods 5-20 milliseconds.
With the help of CV 117, the length of the measurement period at the highest
speed level in steps of 0.1 milliseconds can be adjusted. The range of values ​ ​ f rom
50 to 200 thus enables measurement periods 5-20 milliseconds.
can normally be the measurement period becomes larger with increasing speed
(There are therefore fewer measurements performed) so that ER is maximum
motor power at high speed ranges.
For coreless motors or other agile engines with little flywheel the measurement
period can be reduced to achieve egg nen smoother running.
