fluence 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

0
Same as CV #387 but used during decelerations.

value

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 acceleration.
= 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.
