You may also define your own speed curve: simply enter the desired values in the CVs 67 to 94 (also refer to Fig. 23). The decoder will superimpose these 28 values onto the real speed steps. Thus, you can adapt the driving performance optimally to your locomotive. This mode is only active if bit 4 in CV 29 is set. We recommend using the ESU LokProgrammer for easy and comfortable programming. When this mode is active, the settings in CV 2, CV 5, and CV 6 have no influence.
CV 2 and CV 5 define a scale factor around which the points of the speed curve are scaled. This ways it is far easier to adjust the maximum speed of a locomotive to an active speed curve. Have a look at the speed curve in Fig. 24. The last entry (CV 94) is 255. This represents full speed. If you wish to reduce the maximum speed you only have to reduce the value of CV 5. The decoder computes (squeezes) the speed curve in such a way that the shape of the speed curve remains despite the lower maximum speed. The same is true for the first entry. The speed curve will be raised and scaled subject to the value in CV 2.The CVs 67 and 94 are permanently set to the values of 1 respectively255 in this decoder.
