Programming table of the most important CVs
CV Designation Meaning Area Factory setting
1 Locomotive address DCC address of the locomotive 1 – 119 3
2 Starting voltage Changes the minimum speed 0 – 63 4
3 Acceleration time Value * 0.87 gives the time 0 – 63 8
from shutdown to top speed
4 Braking time Value * 0.87 gives the time 0 – 63 6
from top speed to shutdown
5 Top speed Speed of the locomotive 0 – 63 63
at the top speed level
6 Middle speed Speed of the locomotive at the middle speed level. 0 – 63 25
CV 6 must be less than CV 5
8 Basic setting 8 = Restore basic 8 –
factory settings
17+18 Expanded Long address. CV 17 = higher-value bit, 128 – 9999 0
locomotive address CV 18 = lower-value bit.
Long address must be activated
in CV 29 / bit 5.
29 Configuration register Caution! Very complex! 0, 1, 2, 3, 4, 4
Total value must be calculated. 5, 6, 7, 16, 17,
Total value = value of bit0 + value of bit1 18, 19, 20, 21,
+ value of bit2 + value of bit4 + value of bit5 22, 23, 32, 33,
34, 35, 36, 37,
38, 39, 48, 49,
50, 51, 52, 53,
54, 55
Bit Function Val.
0 Normal direction of travel 0
Inverse behaviour 1
1 14 speed levels 0
28 or 128 speed levels 2
