Diesel Version 5:3 Point Speed Curves Feature

In most applications of acceleration and deceleration the rate at which a locomotive increases its speed forms a curve where the early speed steps do not increase the speed as rapidly as later speed steps. Whereas User Loadable Speed Tables have 28 individual speed steps to adjust and allows for speed plateaus, dips, and non-continuous speed curves, for most applications a simple Speed Curve will be more than adequate to create the prototypical movement of most locomotives. To this end Speed Curves employes 3 CV’s, each defining the rate of speed of a given range of speed steps. Using the Start Volts, Mid Volts, and Top Volts the speed steps from 1-128 are divided into three equal sections. Adjusting the values in the corresponding CV’s shifts the standard speed curve up or down (within the specific range) thereby creat-ing an entirely new rate of speed from each speed step to the next. CV 2 CV 6 CV 5 3 P oint Speed Curves Usage and Adjustment: T o enable 3 P oint Speed Curves simply program values into CV 2 (Start V olts), CV 6 (Mid V olts), and CV 5 ( T op V olts). The Speed Curve is d e fined in CV ’ s 2, 6 and 5 with each CV corresponding to approximately 1/3 of the speed range. V alues may range from 1 - 255 and every value of 18 (approximately) added to one of the Speed Curve CV ’ s adds about 1 volt to the motor speed at the CV being adjusted. NOTE: 3 P oint Speed Curves do not allow for parabolic speed curves. That is to say each consecutive CV must have a value higher than, or equal to, the CV before it.
