CV 2.512 (DDE Load Sensitivity) is used to adjust the correlation between motor load and 
traction motor sound effects. As the motor is impeded during operation, the DDE processor and 
back-EMF circuitry will adjust the volume of traction motor sound effects according to the value 
of CV 2.512. You may enter a value from 0 to 255 into CV 2.512 to adjust the DDE load 
sensitivity level. Entering a value of 0 into CV 2.512 will disable DDE load sensing and sound 
effects will not be modified when the motor is impeded. Setting CV 2.512 to 255 indicates that 
the traction motor sound effect will be most sensitive to changes in motor load. 
 
Note: 

DDE Load Sensing is disabled if Back EMF is disabled in CV 217.
