11.1.2. Adjustments for other Motors / „Fine Tuning"
Unfortunately, the motors available in the market have
considerable variations due to tolerances. This is even true for
the same type. Therefore, LokPilot decoders enable you to adapt
load compensation to the motor with CVs 53, 54 and 55. If the
recommended values above do not lead to acceptable results,
you can further optimise them.
However, before doing this you must make sure that there are
no capacitors wired between the motor terminals and the chassis.
The commutator of the motor must be clean and the drive system
should run freely. The wheel contacts and other contact plates of
the locomotive must also be clean and make reliable contact.

11.1.2.1. Parameter „K"
Parameter „K", stored in CV 54, influences how strongly load
control will affect the driving performance. The higher the value,
the more load control will respond to any changes and try to
adjust the revs of the motor.
Parameter „K" needs adjustment if the locomotive runs unevenly
(jerks) in speed step 1.
Reduce the value of CV 54 by 5 and test-run the locomotive to
see if there are any improvements. Repeat these steps until the
locomotive runs smoothly at speed step 1.
With some motors, it may be necessary to set the starting voltage
to a value between 4 and 6 in order to arrive at good results.
