CV2 determines the motor speed at step one if CV29 bit 4 is zero.
Increasing CV2 increases the initial motor start speed. If BackEMF is
disabled, this value must be high enough to overcome the initial
locomotive inertia (See also
Note: CV2 must be
smaller than Vmid and Vhigh.
CV2, CV5, CV6, CV65 and CV95 allow motor control using a simple
line function. The start speed, the maximum speed, the mid range
speed and compensation for a motor that runs faster in one direction
or the other are determined by these 5 CV’s. Whether BackEMF is
enabled or not (
), the following graph illustrates how the CV’s
control the motor speed characteristics.
