The overall intensity of load compensation can be defined
with
CV #58 from no compensation (value 0) to full com-
pensation (value 255). Useful values range from 100 to
200.
For a more precise or complete load compensation
throughout the full speed range use CV #10
*
and CV #113
together with CV #58 to define a 3-point curve.
*
This applies to MX decoders. For MS decoders CV #10
is already used for another function. If CV #58 is imple-
mented later, another CV number will be assigned here.
CV
Denomination Range Default Description

BEMF intensity
SW version 5.00 and
higher
0 - 255 255
Intensity of back-EMF control at the lowest speed step.
EXAMPLES:
CV #58 = 0: no back-EMF
(like unregulated decoders)
,
CV #58 = 150: medium compensation,
CV #58 = 255: maximum compensation.
CV #151 - Motorbrake
This brake is useful for vehicles without worm gears to prevent them from rolling away or picking up speed on de-
clines as well as to prevent a heavy train from pushing a standing engine downhill.
CV Denomination Range Default Description
#151
Reducing the motor
regulation in consist op-
eration.

9: In case of “zero power supply to the motor”
(Motor PWM = 0) the speed to the desired speed
step is still not reached (speed is still too high),
the motor brake is slowly activated (distributed on
1, 2, ... 8 seconds until the full effect by short circuit
on the motor through the power amplifier).
The higher the value, the faster and harder
the brake is applied.
= tens digit (1-9): Reduction of the motor regulation if
consist-key is active. The values 1-9 in the tens digits
in CV #151 reduce the control to 10
% - 90 % of the
value set in CV #58.
The basic acceleration and deceleration times (momentum) are set with
CVs #3 and #4
according to the relevant NMRA standard, which demands a linear progression (the time between speed
step changes remains constant over the whole speed range). For smooth drivability use values 3 or
higher but for really slow starts and stops start with a value of 5; values higher than “30” are seldom
useful, except in combination with the “braking key”.
The sound project in sound decoders always comes with different values in CVs #3 and #4 (as well as
many other CVs) than what is listed in the CV table. Often the sound can only be played back correctly
in combination with the acceleration times provided by the sound project (or certain minimum values).
Therefore, the sound project’s default values should not be changed too much.
CV Denomination Range Default Description
#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.
#4
Deceleration time
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!
#23 Acceleration variation 0 - 255 0
For a temporary elevation/decrease (Bit 7 = 0/1) of the
acceleration time defined in CV #3.
#24 Deceleration variation 0 - 255 0
For a temporary elevation/decrease (Bit 7 = 0/1) of the
deceleration time defined in CV #4.
#111
Emergency
delay time
0 - 255
0 This CV value is valid for emergency stop instead of CV
#4, i.e. for single stop and collective stop emerg.
#123
Adaptive
Acceleration and decel-
eration momentum
SW version 5.00 and
higher
0 - 99 0
Raising or lowering the speed to the next internal step
occurs only if the preceding step is almost reached. The
tolerance for reaching the preceding step can be defined
by this CV (the smaller this value the smoother the ac-
celeration/deceleration).
Value 0 = no adaptive accel. or decel.
Tens digit: 0 - 9 for acceleration (1 = strong effect)
Ones digit: 0 -
9 for deceleration
= 11: strongest effect
#394
Bit 4: Faster
Acceleration
0 - 255 -
Bit 0 = 1: Light flashes at switchgear sound.
Bit 4 = 1: Faster acceleration and sound to high perfor-
mance when slider is moved quickly to full speed
Bit 6 = 1: Impedes acceleration if brake key is active

Important note regarding acceleration behavior - difference to ZIMO decoders of the MX-series:
The acceleration and deceleration behavior according to CVs #3 & #4 refers to the speed steps that are established
by the speed table (including interpolation states), both with 3-point and 28-point speed table. This means, an expo-
nential - not linear - speed table also triggers a corresponding acceleration and deceleration behavior. Usually (and
by default) such a non-linear speed table is defined.
MX-decoders adjust acceleration and deceleration in 255 equidistant speed steps, regardless of the speed table.
Therefore, the MX-decoders have special CVs #121 and #122 to change the speed table to an exponential rate,
which is not needed with the MS-decoders.
