#387 Acceleration influence
on diesel sound steps
0 - 255
0
In addition to the selected speed step (as defined
in the ZSP flow diagram), actual changes in speed
(acceleration, deceleration) should also have an
influence on the sound due to the associated in-
crease or decrease in load.
= 0: No influence (sound depends on speed step
only)
= 64: experience has shown this to be a practical
value
= 255: maximum acceleration response
(highest sound step during acceleration)
#388 Deceleration influence
On diesel sound steps
0 - 255
0
Same as CV #387 but used during decelerations.
= 0: No influence (sound depends on speed step
only)
= 64: experience has shown this to be a practical
value
= 255: maximum deceleration response
#389
Limited acceleration in-
fluence on diesel sound
steps
0 - 255
0
This CV determines how far the sound step may
deviate during acceleration from the simple speed
step dependence (= difference between target
speed from the controller and actual speed).
= 0: No deviation; motor sounds according to
schedule, sound does not depend on accelera-
tion.
= 1 - 254: Dependence increases with value.
= 255: fully dependent on target speed.
#390
Momentum reduction
when driving solo (en-
gine only)
0 - 255
0
When switching to solo driving with key defined in
CV #347 the momentum reduction is activated
(with CV #348, Bit 1):
= 0 or 255: No reduction
= 128: Reduction to 50%
= 64: Reduction to 25%
= 1: virtually cancels all momentum.
#391
Driving with
idle sound, when driv-
ing solo
0 - 255
0
The diesel motor sound should remain at idle
when driving solo (with function key defined in CV
#347), until the speed step defined in CV #391 is
reached.
#836
Motor Start Sound
Bit 0
0
Bit 0 = 1: Loco shall not start driving before Start
Sound is fully played.

soduring

0
Likelihood for sparks (as per CV #158 Bit 7 for
FO7 or #394 for FO6) when accelerating

= 255: very often (almost always)
#379
Statistical probability

deceleration
in SW version 5.00 and
higher
0 - 255
0
Likelihood for sparks when decelerating (as per

= 0: always
= 1: very rarely
= 255: very often (almost always)
#364

Speed drop during

and higher
0
This special CV applies only to diesel-mechanical
engines and defines the
typical drop in speed when shifting up.

Switchgear
Upshift rpm
In SW version 5.00
and higher
0
This special CV applies only to diesel-mechanical
engines and defines the
highest rpm before shifting up.
