27 speed steps, too)

Form the speed curve with
CV2, 5, 6

Use speed table CV67 – 94
Use primary address (CV1)
5
Use extended address (CV17,
18)
*) Lenz digital plus system version 2 counts the
bits in reverse order from 1 to 8 unlike the
GB
NMRA standard.
Tip: mostly used values for the CV29 (the
default value is usually 6):
CV29= Description
0 (8)* 14 (27) speed steps, primary address,
no analogue operation
2 28 / 128 speed steps, primary
address, no analogue operation
4 14 (27) speed steps, primary address,
analogue operation possible
6 28 / 128 speed steps, primary
address, analogue operation possible
38 28 / 128 speed steps, 4-digit address,
analogue operation possible
* When using the "old" Arnold command sta-
tion, the input of "0" is not possible, instead
enter "8".
◆ CV49, 50 (special effects): With the CV49 and
50 you can set special light effects to the function
output (e.g. allow dimming, the value is in CV55).
CV-No. Color of wire
49 white
50 yellow
Add the required value (1, 2, 4, 8 or 16) for the
desired lighting effect to the operating condi-
tions and enter the result into the appropriate
register. Value 0 switches off all effects of the
output, only ON and OFF is active. If the inten-
sity of the lamps is too high because of the high
digital voltage, you can reduce that by dimming.
enter the value 16 into the CV of the appropriate
light output. The value for dimming (brightness)
is set in the CV55.

0. If you use F1 to F8 for controlling the outputs
you can set a directional condition.
◆ CV53, 54 (parameters of the load control): With
these CVs you can adapt the load control to
many different motors and drive systems. the
proportional parameter P in CV54 determines
the intensity of load control. The greater the
P-component (16 – 32) the stronger the control
effect, however, this results in a higher creeping
speed. The integral component (I-parameter)
in CV53 determines how quickly the decoder
responds to deviations from the desired (set)
speed. The I-parameter should be reduced for
coreless motors (1 – 3), higher values (2 – 8) for
motors with large flywheels. If the I-component
is too high it may lead to speed fluctuations. If
you increase the I-parameter you should also
increase the P-parameter.
◆ CV55 (cycle time of effects / dimming rate):
With the digit (x0...x7) in CV55 the brightness
for the function output is set. 0 represents full
brightness, value 7 the lowest brightness. With
the tens digit in CV55 (0x...9x) you can pro-
gram the repeat rate of the effects (CV49, 50).
0 represents a cycle time of 0.5 sec, value 9
represents a cycle time of 4.5 sec.
◆ CV56 (user-configuration register 1): Here you
can select additional features of the decoder, for
example activating the load control or selecting
the function of output B. Add the values for the
desired functions and enter the result into CV56.
At value 1 the directional lighting feature is
deactivated. F0 now controls output A via the
white wire. With the yellow wire the output B will
be controlled through the function set in CV58
(F1 – F8).
