Schraddel Wrote:If it may help here the CVs of some sound equipped locos which had before a jerky start and stop behavior:
Atlas Genset 2 (with the new not so good motor as before) :
CV10: BEMF cutout 0
CV 67: 3
CV 68: 5
Then a straight line to
CV94: 109
CV209: KP Coefficient 24
CV210: KI Coefficient 10
CV212: Motor Control Intensity (BEMF Feedback Intensity) 255 (100%)
CV213: Motor Control Sample 15
CV214: Motor Control Aperture Time 15
CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140
Athearn Genesis GP9 (Roco motor) with OEM Sound:
CV10: BEMF cutout 0
CV 67: 3
CV 68: 7
Then a straight line to
CV94: 128
CV209: KP Coefficient 80
CV210: KI Coefficient 2

CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140
Bachmann ALCO S-2 (Bachmann motor, a not so good runner) with OEM Sound
CV10: BEMF cutout 0
CV 67: 1
CV 68: 4
Then a straight line to
CV94q: 128
CV209: KP Coefficient 30
CV210: KI Coefficient 10
CV212: Motor Control Intensity (BEMF Feedback Intensity) 255 (100%)
CV213: Motor Control Sample 11
CV214: Motor Control Aperture Time 20
CV215: BEMF Gain Coefficient 2 = ON
CV216: Voltage Adjustement (DCC RMS Voltage) 140
I hope this may help you to set your decoders, after changing the CVs the starts and stops smoothens out. And all will used for switching duties.
Cheers Lutz
Lutz....I have 2 questions....#1) the CV values that you list here...these are the new ones to make improvement? Yes?
#2). When you write on these locos the red words " Then a straight line to.." What do you mean?
Thank you,
