Note:

-P0362 = 100 % corresponds to rated motor flux

-Rated flux = rated EMF

-The value belongs to the first magnetizing current value and must be smaller than or equal to magnetizing curve flux 2 (P0363).

-If the magnetization values entered in P0362 to P0365 respectively P0366 to P0369 do not match the conditions (see below), a linear characteristic is applied internally.
