LGB 20271, Instruction Manual

17

(depends on loco model, do not change, as functions

can be affected or destroyed)

CV52

Command for front lighting terminal (see CV51)

[128]

CV53

Command for rear lighting terminal (see CV51)

[64]

CV54

LGB configuration

Bit programming

Bit 1: hand-off function, 0 = off, 1 = on [0]

Bit 2: MTS Back-EMF, 0 = off, 2 = on [2]

Bit 3: analog Back-EMF, 0 = off, 4 = on [0]

Bit 4: not used [0]

Bit 5: 0 = F1 constant, 16 = F1 flashing [0]

Bit 6: 0 = F2 constant, 32 = F2 flashing [0]

Bit 7: sound function (0 or 64) [0]

Bit 8: sound function (0 or 128) [0]

To program, add the values for the individual Bits and 

program the resulting function value. The values for 

Bits 5-8 vary between locos. The values for your loco

can be read using the 55045 MTS PC Decoder Programming

Module.

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.

CV55

Reset factory pre-set values for CVs

Program:

6-55->

5-55->

CV56

Voltage for function terminal F2

(1-32)

[5]

(depends on loco model, do not change, as functions

can be affected or destroyed)

CV57

Command for function terminal F2 (see CV51)

[15]

CV58

Pause time (analog operation) (0.5 seconds x function value) (0-255)

[0]

When the polarity of the analog track voltage is reversed,

the loco waits for the programmed time period, then 

accelerates in the new direction

CV60

Back-EMF: Max. adjustment factor

(1-255)

[4]

Specifies the max. increase or decrease of voltage applied 

during each time interval (programmed in CV61)

1 = small steps, 255 = large steps

The factory pre-set values of CV60 and CV61 are optimized for 

LGB motors.

CV61

Back-EMF: Adjustment frequency

(0-255)

[16]

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

0 = immediate adjustment, 255 = maximum delay

CV62

Back-EMF: Max. Adjustment

(0-255)

[255]

Limits the total adjustment in motor voltage. If there is a very l

arge load on the motor, the adjustment will not exceed this 

value - for more realistic operations, so that locos will slow a 

bit on grades. 0 = no adjustment, 255 = maximum adjustment
