KNX and Somfy motors

[ecolead]

again and again, sorry for writing in English.
I have two somfy motors, one is
LT 60 Vega 60/12 which is 4 wirs
and another one is
altus rs 50 io 50/12 which is 3 wires
and MTN649912 Blind / switch actuator

I think the 4 wires one will work easily with my blind actuator, but I do not understand the 3 wires one.
how could connect 3 wires one to knx? can anyone provide me with more details related to somfy protocols and how it works?

[knxPaul]

the 3 wires are:

1. Phase L
2. neutral conductor N
3. earth ground connection PE

They are for the power supply only. The control circuit is integrated into the motor electronics to urge any customer to buy somfy products only. As far as I know there is no way to control the altus rs 50 io 50/12 using a KNX system.

oh so it is really impossible to use that one.
Thank you for answering, i appreacte it
