11.1.3.2. blanking interval
With the help of CV 118, the length of the blanking interval can be set at driving
stage 1 in steps of 0.1 milliseconds. The value range of 10 to 40 allows blanking
intervals 1-4 milliseconds.
With the help of CV 119, the length of the blanking interval at the highest speed
level in steps of 0.1 milliseconds can be adjusted. The value range of 10 to 40
allows blanking intervals 1-4 milliseconds.
Normally, the blanking interval is slightly larger at high speed in order to obtain
more accurate measurement results. Especially with old engines larger blanking
interval can lead to more accurate measurements, since disturbances can be
smoothed away.
11.1.4. Automatic motor calibration
5 LokSound decoder enable automatic calibration of motor parameters. This
process often leads to egg nem very good load regulation behavior. A good
result can not be guaranteed in any case, because of the infinite number of
combinations of engines and transmissions, however. It's worth a try. Proceed
as follows:
• Put the vehicle on a straight section of track, if possible without any slope. The
track must be so long that the locomotive ca can drive at full speed to 2 sec-
onds. This will be done automatically during Einmessens. Provide bumpers and
the like, can thus the locomotive does not crash or derail!
• Call the locomotive on your hand control to, and make sure that the F1 key is
turned off and the engine is off. Set the direction of travel as you would like the
locomotive to drive off.
• Now write the value in the CV 54 0 (on the programming track or by means of
the main track programming)
• Now press the "F1" key. The locomotive will now sit down automatically at full
speed in motion. You will not be controlled during about 1.5 seconds!
• The engine will stop automatically and the Lastregel- determined are stored in
the parameter CVs 51, 52, 53, 54, 55th
You can now based on these values further optimizations make to the load
control parameters.
11.2. switch off load regulation
The load control can be turned off by writing CV 49 Bit 0 with 0.
When switched load control in the starting voltage CV2 should be increased so
that the locomotive just starts at speed level 1 or the second
11.3. Adjust load control frequency
Normally, the load regulation of the LokSound decoder works with 40 kHz. It
may be useful to reduce this frequency:
• The motor has inductance little "power" due to high (self)
• The built-in If suppressors such as capacitors, chokes, etc.) disturb load control
but can not be removed (eg some older locomotives Gützold®). The PWM
frequency may be provided in single CV 9 as a multiple of 1000 Hz. The range of
10 to 50 allows frequencies from 10 kHz to 50 kHz.
11.4. Settings for C-Sinus Motor
LokSound decoder with 21MTC can SoftDrive C-Sinus motors indirectly via the
installed in the locomotive control electronics. The LokSound can ersignale
generate all necessary tax, provided you readjust certain settings: Load
compensation must be turned off, as described in Section
11.2. shown.
The control electronics of the motor also need a switchable logic voltage, which
can make the LokSound about AUX4 for encryption addition. So AUX4 must be
active, both in the state and during the journey (both ways!) Describe the
following CVs with the appropriate values. Make sure that CV 31 to value 16 and
CV 32 contains the value. 8
