8 CV - Overview; CVs in numerical order
This overview summarizes all CVs in numerical order; mostly identically adopted from the descriptions in
the preceding (context-related) chapters of this manual, in some cases shortened. In this CV overview
there are
NO notes to SW versions (from SW version ...; see context-related chapters) .

3.4 #1 Locomotive address
DCC:

MM:
1 - 255
3
The “short” vehicle address (DCC, MM)
In case of DCC operation:
Primary address as per CV #1 is only valid, if
CV #29 (basic configuration), Bit 5 = 0.
Otherwise, the address per CVs #17 & #18 is valid,
i.e. if CV #29, Bit 5 = 1.

1 - 255 1
Internal speed step (1 - 255)
applied as
lowest external speed step (= speed step 1)
(applies to 14, 28, or 128 speed step modes)
= 1: lowest possible speed
3.7 #3 Acceleration time 0 - 255 (2)
The value multiplied by 0.9 equals acceleration time in
seconds from stop to full speed.
The effective default value for sound decoders is usually
not the value given here, but is determined by the loaded
sound project.
3.7 #4
Braking time
(Deceleration)
0 - 255 (1)
This CV, multiplied by 0.9, provides the time in sec for
the deceleration from full speed to stop.
The actual default value: see above!

Internal speed step (1 - 255)
applied as
highest external speed step (i.e. for the exter-
nal speed step 14, 28 or 128, depending on the speed
step mode according to CV #29, bit 1 = 0:
=0: equals 255 as highest speed step
=1: equals 255 as highest speed step

Internal speed step (1 - 255)
for
medium externa speed step (i.e. for the external
speed step 7, 14 or 64, depending on the speed step
mode 14, 28 or 128 according to CV #29, bit 1)
”1" = default (Medium speed is set to one third of the top
speed. I.e. if CV #5 = 255 the curve is the same as if CV
#6 would be programmed to 85).
The speed curve resulting from CVs #2, #5 and #6
is automatically smoothed out, therefore no sharp bends.

145
(= ZIMO)
Reading out this CV always result in “145” (”10010001”),
the number issued for ZIMO by the NMRA.
Additionally, this CV is used to start various resetting pro-
cedures by Pseudo programming.
“Pseudo programming” means that the entered value is not really
stored, but rather used to start a defined action.

HARD RESET (NMRA standard);
all CVs return to the last active CV set or

to the default values listed in this CV table.

= 55: Default motor control with high frequency (20 kHz),
medium EMF sampling rate that adjusts between 200Hz
(low speed) and 50Hz and medium EMF sampling time.
= 0: equal to 0 (is converted automatically)
<> 55 and <> 0: Modification of the default setting,
each divided in: tens digit for sampling rate
and ones digit (sampling time).
Tens digit 1 - 4: Sampling rate lower than
default (less noise)
Tens digit 6 - 9: Sampling rate higher than default
(to combat juddering!)
Ones digit 1 - 4: EMF-sampling time shorter than
by defaiult (works well for Faulhaber, Maxxon, ...
less noise, more power)
Ones digit 5 - 9: EMF-sampling time longer than default
(may be needed for round motors or similar)
