There is no initial position detection in InstaSPIN-Motion which force the rotor to zero position by using the Rs re-calculation function during start run the motor at the first time.

so the function of Rs re-calculation on line must be opened when applying a positioning loop

Correct. It's necessary to force the rotor position to a initial angle.
