4.1 Capacity and protection equipment
The motor output has a current-carrying capacity of up to 1A even without special installation on
cooling surfaces! The short-term maximum current-carrying capacity is 1.8A. The function outputs
have current-carrying capacities of 100mA each.
The decoder is protected against short circuits. 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 deleted via programming.
4.2 Motor control
The decoder has a high-frequency control (23kHz). To adapt it to the type of locomotive used, you
can choose between six different motor types in CV50. 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.
