Kernow D600 Warship running problems and solutions

[zoomer1979]

Hi all,

 

A tale to tell that started with a Christmas present for my Dad from me of a Kernow D600 Warship. One of the latest batch, which is significant, as they have used a coreless motor.

After receiving his present he decided that the sound chip he likes the best is Roads and Rails. Chip arrived and fitted but running is now poor with a stuttering start and low top speed. The model was sent to R&R to see what he could do, it came back with more speed but still a stuttering start. Model Rail Scotland last month we decided to ask @charliepettyif he could find a fix. He was doubtful, explaining coreless motors are terrible for controlling. Without any further possibilities and having built up my knowledge of the Loksound V5 I decided that reducing the frequency of the PWM and picking a nominal value for the EMF. feedback value might produce a better running model. It worked. So along with other CV values learned from other setups here are CV values that work for the loco in question:

CV2-1 CV3-60 CV4-60 CV5-205 CV9-15 CV49-17 CV51-10 CV52-0 CV53-100 CV54-28 CV55-240 CV56-30

Hope this helps anyone who is having similar problems with either the D600 Warship or the Loksound V5.

Neil.

Coreless motors are not a problem for control - I've been using them with DCC control for over 15 years.   The problem is finding suitable settings, and some people's prejudice against anything a little different. 
There are a few models around which are mechanically poor, which happen to also include a coreless motor - the problem is the mechanical design, not the motor.  

In ESU's home market of Germany, there are dozens of RTR models with coreless motors, its not a "new thing".  So, suitable settings are possible.  

 

( No comment on the range of settings you tried - if it works for your model, you have a result ).

As I too have a D600 Warship for which I'm looking to fit sound , that's good to know so thanks for sharing!

We have tried our Class 41decoder in the model and all seems OK, not sure re the Roads and Rails one though.

I have just installed the sound project from Richard (Roads and Rails), and I love it. Start off is very slightly jerky on the initial tests, but the rest is fine, including the top speed which is a bit too fast for normal use on my layout. I haven't tried tweaking anything yet, but the first thing I would do is lower CV2 start voltage. 

Even so, I have stored Neil's settings for possible future reference.

I have only just seen this post and can concur that the motor is easy enough to control. I made a video of it and if you cut through the crap of my waffle at the start and see the loco running it seems fine. I am, however, using a Zimo MS440 decoder.
