Important:
If the motor “whistles” after being placed into
service, you probably forgot to enter the standard
values again.
The values to be entered for VAI are explained
below:
Swapping the Connections (Velo)
If you have mixed up the connections when in-
stalling a decoder in an open wiring situation, you
can “correct” for this electronically. First check
which connections have to be changed, and then
enter the number from the following table as a
value:
Motor
Light Track Number
x x – 7
– x – 6
x – – 5
– – – 4 (standard)
x x x 3
– x x 2
x – x 1
– – x 0
Important:
Changing the connections for the motor or the
track will result in corresponding changes in
analog operation.
AFB Effectiveness
With this you can set whether the programmed
acceleration / braking delay is only to be effective
in the (diode) braking area or always effective
(even when the hand controller is being used).
always in effect 1
only in stopping areas 2
Other numbers are not permissable.
Variations in Motor Control
With this value you can adapt the control for op-
timal operation of the motor. There is no general
rule on which variations result in the best control
behavior. The only thing that can help is to make
test runs of the locomotive.
very hard 1
hard 2
soft 3
very soft 4
Caution:
Control variation 4 is recommended for can
motors with bell-shaped armatures, and in the
standard settings pulse width 1 is also recom-
mended for these motors. There is no coverage
under the warranty for damages to motors as a
result of incorrect settings.
