[Solved] Voltage distributor for 2 shutters - request for verification

I have 2 roller shutter motors connected to one box, the motors are to work together and be controlled by one double up/down button. Originally there was an up/down button alone (you had to hold it) and the roller shutter motors were connected via a distributor like the one in the photo. The button went into EINGANG, the first motor was plugged into M, the second motor was plugged into AUSGANG.
.
.
This was undone during the overhaul.
I want to put in a controller - ZAMEL/SROL-S - controlled to the N. The pushbutton will short-circuit the controller's inputs and its outputs will feed the phase to the EINGANG up/down and the rest should be connected as before, i.e. one motor phase up/down with M and the other motor phase up/down with AUSGANG. I plug the phase into the L distributor input. The neutral of the motors should be connected in this manifold.
Something that puzzles me is this phase control. I'm rather low on voltage and always prefer to control to N and just let the phase go, so a request to more electrically advanced colleagues - is my reasoning here correct? Thanks in advance.

Is it good for two motors to be controlled together?

Low voltage does not kill. With higher voltage the idea is that the device is not permanently live (L), so you "control" L and not N.
If you "controlled" N then the device would always be live (L) and there would always be a risk of shock.

OK, thank you for your valuable comment regarding phase control. As I wrote - I'm a low-current guy, and the hazardous voltage is always controlled by a relay or a controller, hence the shortcomings in terms of controlling, for example, a roller shutter button without a controller. So I understand why phase control. Are you able to take a look at this module and possibly explain if I understand correctly - the phase is connected to EINGANG L, and the phase is also connected to EINGANG UP or DOWN, depending on how the motor is supposed to work, and then this distributor "transmits" this phase connected to EINGANG L to the appropriate MOT and AUSGANG outputs, depending on where the phase appears on EINGANG UP/DOWN, is it so?

that's what the distributor is for, it was originally installed with a push button, but after talking to the man from the company that installed these roller shutters and giving them the model of the controller that I wanted to install, they said that it is possible without this distributor, However, when I connected two roller shutters to one controller, when the limit switch on one motor stops the roller shutter when it is fully closed or open, and the other motor is still working, the first one makes a strange noise - this cannot be because the motor will eventually die. Hence, I have to fit this distributor behind the controller or add a second controller.

Let's start with the fact that everything was wrong from the beginning....
These controllers are used to control individual roller shutters using individual buttons and all roller shutters/group of roller shutters using a central/group switch/control timer. Each should only be connected to one motor (hence only one M symbol). Eingang (input) is the input of the power and lift and lower pulse from the central switch. Ausgang (output) is the output of power and up or down pulse to the next module of the next roller shutter. M- is probably clear (roller shutter motor), and Einzelbetrieb is the input to the individual switch of just the roller shutter to which the controller is connected.
Secondly - controlling zero is not the same as giving zero to the motor. In some controllers (e.g. F&F) it is possible to control both the phase and zero (only you have to be consistent in the whole system) and in both cases the motor is connected to the phase (of course with correct connection).
In summary, you need to use as many controllers as you have roller shutter motors. Zero or phase control depends on the possibilities of the selected module and your preferences.

I thought I had already written here. Thanks Marek J, that you wanted to help, but I have to point out to you that you are unfortunately mistaken. In the data sheet of this distributor it is clearly described how to use it as it was applied originally by the company which installed the windows, and as I have done it now using ROPAM SROL-S.

You are right. This controller does have that capability. I was wrong, in fact I suggested that most people make a mistake and connect the roller shutter drives in parallel under one M output, which is not allowed!
You wrote that you installed ROPAM. But did you also use the SELVE module or did you connect two motors under ROPAM?
From what I have seen and read, this is not possible and according to the instructions is not allowed.

and ROPAM and SELVE, SELVE after the ropam and to SELVE the two motors. everything works beautifully.

I connected the up and down buttons and the control from the control panel to the SROL-S, to the motor output I connected the SELVE and to the SELVE outputs the two motors
