SILVER Decoder feature set
The following contains a short introduction of the features of the SILVER decoder as
well as information on how to use them.
For more detailed information please refer to the "SILVER decoder" information which
can be downloaded from the Lenz Elektronik GmbH website: www.lenz.com.
Capacity and protection equipment
The motor output has a current-carrying capacity of up to 1A without any concern for
cooling! The short-term maximum current-carrying capacity is 1.8A. The decoder is
protected against overloading, short circuits and overheating. In case of a fault, a bit is
set in CV30 which will state the type of fault which has occurred. This bit can be
cleared via setting this CV to 0. Because of this protection the Silver decoder can work
with motors that have very high stall currents.

100 mA each
Total current-carrying capacity of
function outputs
400 mA
High Frequency Back EMF Motor control
Silver decoders have a very smooth and quiet high-frequency motor control (23kHz). If
necessary, the performance of the decoder can be optimized to one of 6 specific motor
types in the locomotive using CV50. These motor types include parameter sets which
have been specially adapted to the respective models. In addition, it is possible to
perform additional fine-tuning via CV113 or CV114 when selecting motor types 4 or 5.
If desired you can switch off both the high-frequency drive as well as the control
system itself. You can still use CV9 to adjust the repetition rate.
The minimum (CV2), maximum (CV5) and mid (CV6) speeds can be set; the decoder
automatically adapts these desired speed parameters dynamically to ensure a steady,
smooth curve. It is also possible to program a user defined unique speed curve.
The decoder also has what we refer to as a EMF switch which makes it possible to
further adjust the decoder to different motor types. Depending on the motor type used,
it is possible that a digitally controlled locomotive cannot reach an adequate maximum
speed compared to a locomotive in conventional operation. If this is the case, activate
your EMF switch by setting Bit 6 in CV 50. The locomotive will then reach a higher
maximum speed while the minimum speed is also slightly increased.
