I have a question
Czech locomotives have a functional EDB from 0% to 100%, but in Open Rails it is this way:

Open Rails
OFF - 0% to 100%

But in real czech locomotive have
0% to 100%

Is it possible to set it up somehow? Or it is necessary to remake the OR code

[Csantucci]

When you set DynamicBrakesDelayTimeBeforeEngaging to zero you still have the two different OFF and 0 states?

[Coolhand101]

With the 'DynamicBrakesDelayTimeBeforeEngaging' at zero, you will still get the 'off' and '0%' positions.

Thanks

Now ENG OFF - 0% - 100%

Is there any solution?

Hello,

Have you try with this commands too:

ORTSDynamicBlendingOverride ( 1 )
ORTSDynamicBlendingForceMatch ( 1 )


Data of OpenRails manual:

7.3.4 Blended Dynamic Brake
Some locomotives have blended dynamic brake, which means that the trainbrake lever also controls
the dynamic brake. Currently this is implemented to be MSTS compatible, the dynamic
brake force percentage follows the train brake pipe pressure (full service/suppression will set 100%
dynamic brake). The blending percentage run up/ run down follows the airbrake application
MaxApplicationRate(), and release rates MaxReleaseRate(), and also respects the dynamic brake delay
setting DynamicBrakesDelayTimeBeforeEngaging() .eng parameters.
Blending can also work if there is no dynamic brake lever configured for the locomotive. If there is dynamic
brake lever defined, then the higher command will be applied, except if OrtsDynamicBlendingOverride( 1
) is added to the Engine() block, which makes the lever override the blending command, if the dynamic
brake lever is not at full release position.
OrtsDynamicBlendingForceMatch( 1 ) parameter can be added to Engine() block, which makes the dynamic
brake system to try to achieve the same brake force as the airbrake would have (even if the airbrake
is bailed off), in the current train brake lever position. Example: if the trainbrake has 22 kN brake force
at 40% trainbrake setting, then the dynamic brake will try


Helps this youre problem?

I know that there is worked on the code in case dynmamic brake by Csantucci


By some locomotives where i have programmad "Blended" in .eng file and work with "BailOff" i see that Bailoff is working now like in MSTS (under dynamic brake speed, normal pneumatic cylinderbrakefill)

That is very good :-).


In Belgium we have EMU, HLE that brakes EDB too, but when a P/EP Button is switched. In case the ampéreneedle it is play with DynamicBrakesResistorCurrentLimit ( 2000 )

the needle in cabview have scalerange to -600

Piece of Dynamicbraking for that EMU on this moment:

	comment(-------- Frein électrique --------)

    	DynamicBrakesMinUsableSpeed				( 20 )
    	DynamicBrakesMaximumEffectiveSpeed			( 200 )

    	DynamicBrakesNumberOfControllerNotches			( 0 )
	DynamicBrakesHasAutoBailOff				( 0 )

	ORTSDynamicBlendingOverride				( 1 )
	ORTSDynamicBlendingForceMatch				( 0 )

But in the CZ train, works the EDB with a own lever, or blended system?

Howky, for what CZ train/Vlak is this ?

[Howky]

Stijn D.C
This is locomotive 162 RegioJet

[Stijn D.C.]

Ah, But have this Skoda locomotive the same EDB system like CD151, CD150...?

I'am busy with experimenting on a Belgium EMU, but on this EMU the EDB must be work on cylinderpressure value.

But i see that the blended dynamic brake works differtent if you use normal EP brakelever, or work with the PBL2.cs brakescript

I think that the blendedsystem in ORTS works with the function that if blended is programmed in .eng file that a "dynamic brake lever" control the blended function.

Becauze, if i release the brakes the needle of negative ampére, go to quick back to zero, in my case the needle must be slow turn to zero, so if i set brakelever to full release there is a fadeout

what i mean is that the dynamic brake must wait some seconds to swith of, the otherwise way of DynamicBrakesDelayTimeBeforeEngaging ( 0.5 )

-----

But if you said that you need a EDB that go from 0 tot 100% , do you mean in 1 step, are with some steps between it?

Update of my posts:

I have look at information of the CD151 (i test with this locomotive)

I find information on Wikipedia but on http://www.prototypy.cz/?rada=150 too

On Wikipedia i read indeed a section of 3 steps in case dynamic brake lever, ORTS handle Always a extra "off" position

i think it is better that ORTS read the first line of:

Brake_Dynamic ( 0 1 0.1 0
NumNotches ( 3
Notch ( 0.0000 0 Dummy ) Must be read by/for "off" postion ORTS
Notch ( 0.5000 0 Dummy )
Notch ( 1.0000 0 Dummy )
)
)

If you delete the first line and go to 2 NumNotches the lever dont work in ORTS and you can only choose 50% & 100%, and becauze that nice issue in ORTS that you can not give traction until dynamicbrakelever (or blending) is to 0% you can not drive.

 cd_151023_hk.eng (50.42K)
Number of downloads: 344


But for blending in that 3 steps that like me strange, i read in technical data of CD151 that by 100 Ampére Dynamic voltage the brakecylinders of locomotive release. (For moment only bailoff is possible)


I'am not happy that if you set the lever to 0% that the ampéreneedle go to zero in 1 step (if there is not enough tension, you see needle slowly go to zero) that is better.


DynamicBrakesResistorCurrentLimit ( 1500 ) is a important thing to for kalibrate the behavior of dynamic brake.

For this must you know the right value on ampéreneedle of cabview too, on CD151 i can not see it clear, for moment i use 1500.

[Howky]

Locomotive 150/151 controller positions are

+ fast start-up performance
+1 adding a performance by degrees
J drive (holds a set level)
-1 rolling off performance by degrees
0 neutral
-B Electrodynamic brake - brakes release
B keeps setting electrodynamic braking
+B Electrodynamic brake - brake

Hello,

Yes i have see that in cabride of some CS locomotives, that driver give some "ticks" to that handle for the powersteps. (56 if i'am right: http://www.prototypy.cz/?rada=150 )

But you mean that you will that function of combined powerhandle in ORTS?

The 3 steps of Dynamic braking are just for the lever? Homuch steps (like 56 tractionsteps) they are for dynamic braking?


I know that you can made for train & enginebrake scripts, like Serana have do (EDB works better with this on trains where i use that script)


Maybe this type combinedpowerhandle can be realized with a external script too, that is question for experts.

Yes
https://www.youtube....h?v=az-50T-90O8 time 0:03 min-0:27min
0 position decreases tractive power(force) and dynamic power(force)
-B position decreases dynamic power(force)
+B position increases dynamic power(force)

[Stijn D.C.]

And have you an idea howmuch steps there are in the dynamic section?


Greetz,

Stijn

[hroch]

There are no steps/notches in the dynamic section. The locomotive has a fluent change of dynamic brake force. In my post 17 the first picture is the characteristics of the dynamic brake force of the locomotive CD 150 before renovation. The locomotive has DC motors with serial excitation. Traction motors work in a dynamic brake as separately excited. The locomotive has a regulator which works so that when the rotor current decreases, the stator current (excitation current) increases.
