A: For P00.00 = 1,  SVC1. As you know, the motor's power is too small, compared with inverter, the range is too big. So my suggestions for user's reference.
After auto-tuning, try to adjust P02.07 and P02.08's value a little smaller, don't adjust too big, and see the performance.  Or adjust P03.03 a little smaller, 18, 15, see the performance.
Rotor resistance does not affect the output voltage, but it will make the speed identification worse, which will result in higher or lower actual speed (bigger rotor resistance) or smaller rotor resistance (smaller rotor resistance), too large rotor resistance will also cause control instability, too small rotor resistance may cause insufficient output.
Large leakage inductance parameters may lead to current oscillation.
