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 each 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.
