Hi Hakan,
to my knowledge you cannot use a VFD either V/F or sensorless vector mode to achieve position control. I don't think an encoder will help, my Delta VFD can use
an encoder, Delta call it a pulse generator, to get really good speed control but its still not capable of position control.
You need a decent AC servo and drive. I know they are expensive but once you get one you'll never look back.
