SPEED TABLE CV67-CV94 FOR 28 SPEED STEPS
When CV29’s bit 4 is set to “1” it will use the speed table formed by CV67-CV94 to
control speed (motor voltage). It allows you to setup a custom curve speed for all
28 speed steps. First, program CV29 to 18 for short addresses (1-127) or
program CV29 to 50 for long addresses (128-9999) to enable speed table control.
Then select throttle to 28 speed steps and run your loco at speed step 1. Use
program CV on the main to change CV67’s value (1-255) to adjust step 1’s speed.
The kick voltage, CV65 is only applied when the speed step changes from 0 to 1.
You should switch between 0 to 1 many times to check step 1’s speed. When
done with CV67, select speed step 2 and program CV68. CV68’s value must be
greater then CV67’s. When done with CV67-CV94, use read back CV to make
sure their values are in increasing order.
Note: When using MRC Prodigy DCC to program addresses it will automatically
disable the speed table (set CV29’s bit 4 to “0”). Programming CV125 to 1 will also
disable the speed table and re-program CV67-CV94 to a default linear speed
setting.
TROUBLE SHOOTING
This decoder should perform well with all DCC systems. The maximum DCC output
should be less than 18 V. If the locomotive does not respond to commands, it may
have lost its address. Please re-program the address and program CV19 to 0
(disable consist). If it responds to slowly, you should clear its momentum by
reprogramming CV3 and CV4 to zero. If step 1’s speed is too high, you should
program start voltage, CV2 to zero. If its top speed is too slow, program top
voltage CV5 to 31. You should also clean the track to improve electrical pickup.
Read your DCC system manual to learn how to program and operate the decoder.
For more information about registers/CVs and their functions, please refer to the
NMRA DCC Standard & Recommended Practices, RP-9.2.2. This is available
directly from the NMRA or their website at www.nmra.org. Whenever the
decoder doesn’t work please use the program track to program CV# 125 with
value 1 to restore the decoder to factory settings. This should bring the decoder to
life with address #3.
