The decoder is protected against overloading, short circuits and overheating. In case of a fault, the
corresponding bit is set in CV30 which will state the type of fault which has occured. This bit can be
E
deleted via programming.
4.2 Motor control
The decoder is equipped with a high-frequency motor control (23kHz). Six different motor types (not
to be confused with motor designs, such as a bell-type armature motor) can be selected in CV50 to
adapt to the respective locomotive model. These motor types include parameter sets which have
been specially adapted to the respective models. Moreover, it is possible to carry out fine-tuning via
CV113 or CV114 when selecting motor types 4 or 5. Of course you can switch off both the high-
frequency drive as well as the control system itself. You can still use CV9 to adjust the repeat rate.
The minimum (CV2), maximum (CV5) and mid (CV6) speed can be set; the decoder automatically
adapts the characteristic speed line dynamically to ensure a steady, smooth curve. Independently of
this, it is also possible to program an individual characteristic speed line.
The decoder still has a so-called EMF switch which makes it possible to 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.
4.3 Running notches (Speed steps)
The decoder can be operated in the 14/27 or the 28/128 running-notches mode. This setting is
made in CV29.
