Buna ziua, am cumparat si eu second hand un astfel de invertor si ma cam bate.. imi puteti lasa o adresa de email sa va pun 2 3 intrebari scurte? Multumesc anticipat!
Buna ziua, Scuze, acum am vazut comentariul dvs. Email: service@electrosys.ro
Hello I am quite confused how you connected the motor. You have 3 wires from motor. One of them is PE. So only 2 wires left. So its a DC motor, and you have connected it to LENZEs to ''A'' and ''B'' terminals. Youre using AMER MP80s permanent magnet motor. I was under impression that you have to connect ''I'' and ''K'' terminals also, for this unit to function correctly. Very interesting! Theres is not such option mentioned in LENZE manuals.
It's a DC motor, so it use just 2 wires.
Promo sm 👍
Hi; could you please provide a wiring diagram?
