KB651 What is the Digitrax LocoMotion System?

Your locomotives look like the real thing, Digitrax LocoMotion™ System makes them run like the real thing, too!   128 speed step control.   Smooth deceleration to stop before changing direction when locomotive is reversed. No sudden, non-prototypical stops!   Torque compensation for the smoothest operation ever.   Momentum with acceleration and deceleration settings.   Set normal direction of travel for your loco.   Switching speed feature for quick access to slower switching speeds.   Simple 3 step speed tables are easy to set up.   Advanced 28 step speed tables with 256 level resolution.   Scaleable speed stabilization feature. ...

KB924 CV09 - SuperSonic Quiet Decoder Operation

The SuperSonic decoder feature allows you to adjust the PWM (pulse width modulation) frequency of your decoder to reduce the humming noise that is characteristic of the DCC signal.Digitrax decoders that have this feature are shipped with the value set at 000/x00 or maximum PWM.  To change this value, you can set any value from 000/x00 (max) to 255/xFF (min).  Entering a value of "255" will turn this feature off.Use of this feature will make the locomotive run more quietly but will reduce the torque generated by the motor.  Digitrax torque compensation can be used to compensate for this effect.

KB925 CV54 - Torque Compensation & Switching Speed

In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. CV53 is not used in FX3 decoders.Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonicTM operation.  This feature is turned on at the factory.Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.FX3 CV54 Values For Controlling ...
