<p>The <strong>Speed Control pane</strong> looks very complicated, but it can be one of the
|
|
most significant in improving the performance of your locomotive fleet. Remember if you use
|
|
<strong>Speed Table</strong> TAB this TAB is not used.</p>
|
|
|
|
<h1><img src="images/Speed_Table_Main.png" alt="speed" height="386" width="804">
|
|
</h1>
|
|
|
|
<p>Let's look first at the top of the pane: You now have the option of using Basic Speed
|
|
Control (this pane) or Speed Table to control your locomotive's speed. Use the tabs at the
|
|
top of the screen to select the method you wish to use and then click the button in the top
|
|
center for the page to select that method of speed control. Whichever one you select last
|
|
with the button will be the method used for speed control.</p>
|
|
|
|
<p>Now back to Basic Speed Control Pane. We see the <strong>Start Voltage(0-255)</strong>
|
|
slider to set the start voltage. What appears in the body of this panel is dependent on what
|
|
is available from your decoder manufacturer. Most have something similar to what is shown,
|
|
but the Soundtraxx Tsunami series is very limited. We'll show you a way around this
|
|
limitation when we get to the Speed Table screen.</p>
|
|
|
|
<p>Three important CVs are programmed in this pane Vstart, Vmid and Vhigh. They work together
|
|
to make a very basic three point speed table. On some decoders these settings may be labeled
|
|
differently and all three may not be available. DecoderPro will show the correct options for
|
|
your selected decoder.</p>
|
|
|
|
<p>Possible setting that can appear on this TAB.</p>
|
|
|
|
<p><strong>Vstart</strong>(<strong>Start Voltage</strong>) is the voltage at the first speed
|
|
step. If your locomotive didn't start moving until there were three volts on the track with
|
|
analog power, this lets you set up the decoder to give it 2.99 volts right away, so it will
|
|
start moving when you advance your DCC throttle.</p>
|
|
|
|
<p><strong>Vhigh(Top Voltage, Max Voltage, Maximum Voltage)</strong> is the maximum amount of
|
|
power the locomotive will get from the decoder. If your locomotive looks like Chuck Yeager's
|
|
X-1 at full throttle, then you can trim the top speed down to a more reasonable scale level.
|
|
A similar looking limit can be set on the Roster Entry screen, but it only apples to JMRI
|
|
Throttles.</p>
|
|
|
|
<p><strong>Vmid</strong>(<strong>Mid Voltage, Midpoint Voltage)</strong> lets you configure
|
|
the slope between <strong>Vstart</strong> and <strong>Vhigh</strong> a bit, so that if your
|
|
locomotive reaches full speed at 5 volts, you can stretch out the lower end of the curve to
|
|
get more fine control in a useful speed range.</p>
|
|
|
|
<p>If you are having problems with unpredictable speeds with your locomotives, check these
|
|
settings. Sometimes, one or more of these settings have been changed accidentally (usually
|
|
due to an error in programming CV's with a throttle), leading to very odd speed performance.
|
|
In particular, if the <strong>Vmid</strong> is lower than <strong>Vstart</strong> or higher
|
|
than <strong>Vhigh</strong>, results can be highly unpredictable. DecoderPro will not let you
|
|
make this mistake.</p>
|
|
|
|
<p><strong>Forward Trim</strong> and <strong>Reverse Trim</strong> allow you to compensate
|
|
for differences in the forward speed and reverse speed of the locomotive. Most model
|
|
locomotives do not run at exactly the same speed forward and backward due to the motor
|
|
mechanics and the gear train to the wheels.</p>
|
|
|
|
<p>The settings for these controls are not as intuitive as you might think. A setting of 0 in
|
|
these CVs turns them off. However, a setting of 128 in either of them will have no visible
|
|
effect! To make the forward and reverse trim effective, raise the value above 128 to increase
|
|
speed, and lower it below 128 to decrease speed in this pane. The Forward and Reverse Trim
|
|
does not work the same for all decoders, with variations between manufacturers.</p>

<h3>Some suggestions on using the basic motor controls and programming on the
|
|
main.<br></h3>
|
|
|
|
<p>Unless you want to get into some precision speed matching, you probably won't need to
|
|
use the <strong>Speed Tables</strong> you'll see on the <a href="Comp_Speed_Talble.shtml"
|
|
target="_parent"><strong>Speed Table pane</strong></a>- you'll be able to accomplish much
|
|
of what you want using just <strong>Kick start</strong> (<a href=
|
|
"Comp_Motor.shtml">previous pane</a>), and <strong>Start Volts</strong>, <strong>Mid
|
|
Volts</strong>, and <strong>Max Volts</strong> if they are available in this pane... but
|
|
how to do this?</p>
|
|
|
|
<p>Start with the <strong>Kick start</strong> value, and <a href=
|
|
"Programmer_OpsMode.shtml">Programming on the main</a> rather than the programming track.
|
|
Set the locomotive to be programmed on throttle step 1. If it moves <span class="ACCENT">at
|
|
all</span>, don't change the <strong>Kick start</strong> value. If it doesn't move, slowly
|
|
step up the throttle until it does. Then, turn the throttle down. If the locomotive stops
|
|
at the same setting it started, you won't need to set the <strong>Kick start</strong>
|
|
value. However, if it continues to run at a slower speed than it would start, then increase
|
|
the <strong>Kick start</strong> value until it will start and run at its slowest possible
|
|
speed.</p>
|
|
|
|
<p>Now, if the locomotive isn't running at throttle step 1, increase the <strong>Start
|
|
Volts</strong> value (and write it) without changing the throttle until the locomotive
|
|
<span class="ACCENT">barely</span> crawls... you can usually get this down to a speed of a
|
|
tie a minute or so if you like! Remember, you are doing this in "<strong>ops
|
|
mode</strong>", so you can make these changes while the locomotive is actually running.
|
|
Don't forget to write the value changes to the decoder - they won't take effect unless you
|
|
do.</p>
|
|
|
|
<p>Now, set the top speed of the locomotive. Run the throttle up to full, and lower the
|
|
<strong>Max Volts</strong> value (and write it) until the locomotive runs at the maximum
|
|
speed you want it to reach, but don't forget that adding a train will slow it down!</p>
|
|
|
|
<p>Finally, set the <strong>Mid Volts</strong> value about half-way between <strong>Start
|
|
Volts</strong> and <strong>Max Volts</strong>. Setting it above or below the median of the
|
|
<strong>Start Volts</strong> and <strong>Max Volts</strong> values will give you a crude,
|
|
three point speed table.</p>
|
|
|
|
<p>There are no hard and fast rules for the exact numbers to use. Even identical
|
|
locomotives with identical decoders will need different numbers, due to variances in motors
|
|
and drive trains. Experiment with the settings - DecoderPro makes it easy!</p>
|
|
|
|
<p>Note: Not all decoders will have Start, Mid and Max Volts, but will have some version of
|
|
this which will be displayed by DecoderPro for the specific decoder.</p>
