P0362[3]

Magnetizing curve flux 1

CStat: CUT
P-Group: MOTOR
Specifies first flux value of saturation characteristic in [%] relative to rated motor voltage (P0304).
The parameter settings for the values of P0362 to P0365 respectively P0366 to P0369 are illustrated in the
diagram below.

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.
P0365 ≥ P0364 ≥ P0363 ≥ P0362
P0369 ≥ P0368 ≥ P0367 ≥ P0366
