LGB 20670 Instructions De Service page 8

You can program the following registers:
Register Function
CV1 Loco address
CV2 Starting voltage
voltage for speed setting 1 - if loco starts only at a higher
speed setting, increase value.
CV3 Acceleration (1 = fast, 255 = slow)
CV4 Braking (1 = fast, 255 = slow)
Hint: When programming with the 55015 Universal Remote, the following CVs are pro-
grammed by input of the number of the desired CV in CV6 and then input of the desired func-
tion value in CV5 (see example below).
CV5 Max. voltage
Voltage for highest speed step - if a lower top speed is
desired, decrease value.
CV5 after input of CV6
function value for CV to be programmed
CV6 CV to be programmed
CV29 Configuration
Normal direction:
4 = Analog and digital, factory-programmed speed steps
0 = Digital only, factory-programmed speed steps
20 = Analog and digital, user-programmed speed steps
16 = Digital only, user-programmed speed steps
Reversed direction:
5 = Analog and digital, factory-programmed speed steps
1 = Digital only, factory-programmed speed steps
21 = Analog and digital, user-programmed speed steps
17 = Digital only, user-programmed speed steps
With "Analog and digital:"
- Loco can operate on analog and digital layouts
With "Digital Only:"
- Normal operation on digital layouts.
- Operation on analog layouts not possible.
CV54 Hand-off function and "Back-EMF"
32 = Hand-off function off, Back-EMF digital off,
Back-EMF analog off
33 = Hand-off function on, Back-EMF digital off,
Back-EMF analog off
34 = Hand-off function off, Back-EMF digital on,
Back-EMF analog off
35 = Hand-off function on, Back-EMF digital on,
Back-EMF analog off
36 = Hand-off function off, Back-EMF digital off,
Back-EMF analog on
37 = Hand-off function on, Back-EMF digital off,
Back-EMF analog on
38 = Hand-off function off, Back-EMF digital on,
Back-EMF analog on
39 = Hand-off function on, Back-EMF digital on,
Back-EMF analog on
Hand-off function on: When operating with 55015, you can
adjust direction and speed for two seconds after selecting a
moving loco without causing the loco to stop.

Reset of most programmed CVs
55 = most important CVs are reset to the factory pre-set
values
Back-EMF: Max. adjustment factor (0: small, 255: large)
Specifies the max. increase or decrease of voltage applied
during each time interval (programmed in CV61)
Attention! The factory pre-set values of CV60 and CV61 are
optimized for LGB motors.
Back-EMF: Adjustment frequency (0: often, 255: seldom)
Specifies how often per second the motor voltage is adjusted -
accordingly, the loco will react to curves and grades immediately
or with a short delay
Back-EMF: Max. Adjustment (0: small, 255: max.)
Limits the total adjustment in motor voltage. If there is a very
large load on the motor, the adjustment will not exceed this
value - for more realistic operations, so that locos will slow a
bit on grades.
Speed steps programmed by user (see CV29):
28 speed steps are programmed in CV67 to CV94.
With LGB MTS, every second value is skipped (14 speed steps).
Factory pre-set speed steps:
7, 9, 11, 13, 16, 20, 24, 28, 32, 36, 42, 48, 54, 60, 68, 76, 84,
92, 102, 112, 124, 136, 152, 168, 188, 208, 230, 255
Pre-set values for user-programmable speed steps:
8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128,
136, 144, 152, 160, 168, 176, 184, 192, 208, 224, 240, 255
Hint: The speed steps are factory pre-set and programming is
not necessary. Use the 55045 MTS PC Decoder Programming
Module for programming.
