Its C90 (no3)

And its also recommended to do the calibration if you use a new Marklin decoder. Write 77 to cv 7, or replace the first number in the firmware number with 77 when using CS3 and mfx. (but read the manual first)
(currently, it is recommended to avoid English as the system language on the CS3 when programming motor type, because of a software bug)

Hello Fabrice!

I intend to use the series of Märklin's decoders mSD3 (60975/60976/60977).

Thanks a lot for your help!

Francisco

Thank you very much for your answer Fabrice.

I read the documentation before, bur my doubt came because in the Märklin book "Running Trains Digitally with the Central Station 3", on page 122 in the calibration run and the Ideal Running, it says:



And for more problems, the CS identifies the motor as type no 4 (Bell armature).

That's why I had nothing clear.

Thanks a lot to you and bph.

By the way, what are the differences between a High efficency propulsion c90, direct current DC soft and direct current DC hard? I thought that the new conversion kits 60941/3/4 worked with direct current, and the C90 with alternate current.

Francisco

The c90 decoders all required the conversion kit with a magnet, making them into DC motors.

Thank you very much kiwiAlan!

Do you know the difference between type 3 (5 stars C90), type 5 (DC Soft) and type 6 (DC Hard)? I can't find any useful information about this.

Greetings,

Francisco

My personal guess is that DC soft is used as standard and works ok with most motors. But if you change to c90 you will probably get a better result as it is "optimised" for that type of engine. And I notice that they don't use that phrase in the decoder manual.....

eg new locomotives from Marklin with that type of engine, use the c90 setting. I haven't checked all of course but I noticed it in the 37244.

but do some comparisons and test locomotives with different settings and use the setting that gives you the best running.

I read somewhere that DC soft is generally recommended for general dc motors without flywheel, and dc hard is for motors with flywheel.
but I'm not sure about this, since Märklin does not use it consistently. eg the recent SNCF 241, SNCB class 1, BR 02 0314 and DSB class E, are all fitted with the same motor (E264215), but the SNCF 241 and SNCB class 1 is set to DC hard from the factory and the BR 02 0314 and DSB E are set to DC soft from the factory.
On the DSB E, I did a test, and changed the motor settings to DC hard and did a new calibration run, and I feel that the slow running characteristic improved, so I'm keeping that setting.


The readout is probably wrong, due to the software bug. (as mentioned above in #2).
If using English, change the CS3 system language to something else, and you will most likely get a correct reading.
note that the bug in the English software also affects the motor type when you change it. eg if you are trying to set C90 with the cs3, the cs3 actually programs a different motor type.
