Some questions about PZB U mode / Einige Fragen zum PZB-U-Modus

I would recommend you the following website. There you'll find the explanation you seek. It's in German though, but still you should be able to grasp it due to good graphic explanation.
U/M is mostly used for freight trains, that's correct. The correct mode is determined by a calculation of the trains ability to brake ("Bremshundertstel").

I think that can help you:

The three modes have different speed lines:

O:

M:

U:

that means in your case you have to slow down to 55 km/h in 38 seconds (because of that the "55" is flashing)

The PZB mode is determined by your "Bremshundertstel". But this is not a feature in Train Simulator, so you have to rely on the scenario to tell you which mode to use.

Mode O = 1000Hz -> 85km/h
Mode M = -> 75km/h
Mode U = -> 55 km/h
You have a certain time to reach that speed (varies for the mode).

Everything is correct. Maximum allowed speed in "Zugart U" is 55 km/h when the 1000hz indicator lits up.
To avoid a "PZB Beeinflussung" in this case, you have to pass the sign with less than 85 km/h.
You must always slow down to the speed limits given by the PZB mode.

If you look closely on the illuminated PZB indicator in the cab you can see that it says "55". In this case, you have to slow down to below 55 km/h in 38 seconds after passing an active 1000 hz Magnet. The 500 hz Magnet should not be active, you only have to pay attention to it if you are approching a signal at danger or the signalled speed is <30 km/h.

There's an article in the English Wikipedia that explains all kinds of rules and restrictions. I suggest you read it first.

And your emergency brake most likely comes from you pressing "Frei" before passing the 500hz magnet for your only allowed to use "Frei" if there is no other active Magnet in the next 550 meters.

PZB Mode U after 38 seconds lower speed to 55 Kmh. When reaching the 500 Hz Magnet speed should be reduced to 40 Kmh and after another 153 metres lower speed to 25 Kmh. In reality you should always drive 5 Kmh lower than the Pzb Speeds = 50, 35 and 20.

Trifft hier aber nicht zu, da hier die GPA am 7er LF zugeschlagen hat, da ist kein aktiver 500er zu erwarten.

Hab auch erst gedacht, er will nur die allgemeinen Überwachsungskurven wissen.

*editiert* sorry, hab quatsch geschrieben.

Hab das Bild grad aufm Handy leider nicht gesehen und bin aufgrund seiner Schilderung davon ausgegangen dass er in seiner Situation auf Halt gefahren ist. Na dann will ich mal nichts gesagt haben.

There are some problems with the PZB within the route at thisw position. You haven't done anything wrong.
But it is a shame, that there is this problem inside a payware scenario... It is possible to activate PZB messages directly from the signal with the opt. trigger. But it seems, that this is not important for 3DZug. Shame on you 3DZug.

Never use Frei if signal is not clear. Than you got problems on 500hz like you describe. Can be also issue with railworks itself I encounter allot of strange things with Lua script testing

Eine Frage zu dem abgebildeten Signal: ES64F4 schreibt, es das 2. Vorsignal..

Wenn das ein Wiederholer ist, warum steht dann eine Vorsignaltafel davor. Ich dachte, daß bei den Wiederholern keine vorhanden sind.
