Lets suppose 400V AC is mains voltage, ATV71...N4 version used and motor has rated voltage 400V(star) / 230V (delta)

Rated values to be entered for delta connection as written on motor plate , e.g. 2.2kW, 230V, 50Hz, 1420rpm, NCR=xx
Then autotuning.
Operation above 50HZ must be enabled by setting Fmax and HSP up to 87Hz (or above) and check if UCP=400V and FCP=87Hz. UC2=yes.
Do not forget that Altivar must be selected with rated power at least 1.73 * motor power (written on motor plate). e.g. 4kW ATV71...N4 drive for 2.2kW motor.
