P0362[0] : 1st. Drive data set (DDS)
P0362[1] : 2nd. Drive data set (DDS)
P0362[2] : 3rd. Drive data set (DDS)
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.
