Köszönöm a segítséget, közben válaszolt az MTB is:

"Hello,

pls use MP4 instead of MP5, which will be closed soon.

pos1/pos2  has  end limit switches,  motor will be disconnected after  reaching end position.

but if you use pos1/POS2  togheter, then MP will run  permanently and after one minute will burn out, by heating. !!
DO NOT DO it !!.
