Rapido Trains F40PH-2D Operating Instructions Manual - Awesome Slow Speed Thingy

AWESOME SLOW SPEED THINGY

There is an awesome trick that you can use to get even better slow speed running and 

smoother operation. It’s called the Automatic Motor Tuning Feature. This feature will 

automatically adjust the Back-EMF in most cases and give you phenomenal slow-speed 

performance.

In order to use this automatic adjustment you need to use Ops mode programming, i.e. 

programming on the main. Make sure your locomotive is in “forward” and that you have 

lots of room in front of it on your mainline. Set CV 54 to a value of 0. Then get out of 

programming mode and turn on the bell (press F1). We’ll say this again: Make sure you 

have plenty of room in front of your locomotive and it is not headed for the layout edge 

and the basement floor!!! 

Your F40PH-2D will quickly take off at full speed and gradually slow down to a stop 

while the decoder reads the motor responses. You’ll have fabulous motor control after 

you do this. If you ever have to reset your locomotive, you can do the automatic adjust-

ment again – it just takes a few seconds.

MORE INFORMATION

While addressing the features that most modelers will need for normal operation, these 

instructions have covered just a small number of the many customizable features of 

your ESU LokSound decoder. For advanced users who want to more fully explore the 

capabilities of the decoder we suggest downloading the ESU Loksound Select decoder 

manual. This is available on the F40PH-2D page in the Support section of our web site.

LIMITED LIFETIME WARRANTY

We will do our best to solve any problems or issues that you may have with your  

F40PH-2D locomotive. If your locomotive has any defects that originate from the factory, 

we will repair your locomotive using new components or replace it outright should a 

repair not be possible. However, we can only replace your locomotive while we have 

additional ones in stock. We normally keep spares for up to six months after a model is 

released. If you purchased this locomotive or first opened it after that time, it is possible 

that we no longer have any replacements and that a repair is the only option. Please 

give us a call or write us an email, and we will see what we can do to help you out.

There are a number of things that this warranty can not cover. If your F40PH-2D arrives 

with a couple of loose grab irons or underbody bits, there is a very good chance that 

you can effect a repair in less time and effort than it would take to contact us. Don’t be 

afraid to do some model railroading! White glue, such as Weldbond, works wonders 

for securing all sorts of parts and will not mar or damage your paint. However, if parts 

are missing that is another story – call us or send us an email and we’ll send you some 

replacements.
