Measurement of:
P 470[0] - MOT_Rstat
: Stator resistance,
P 476[0] - MOT_
Rrot
: Rotor resistance,
P 471[0] - MOT_Lsig
: Leakage inductance
l
Maximum effective current Idmax
P 474[0] - MOT_LmagIdNom
l
Operating point calculation:
P 462[0] - MOT_FluxNom
: Nominal flux,
P 340
[0] - CON_FM_Imag
: Magnetizing current
l
Calculation of: current, speed and position control parameters
l
Click the "Start calculation" button to determine the rotor resistance
P 476[0] -
MOT_Rrot
and leakage inductance
P 471[0] - MOT_Lsig
.
l
Measurement of the saturation characteristic (table values of the stator
inductance
P 472 - MOT_LSigDiff
);
Measurements are taken up to four times rated current, provided the power
stage current permits it at standstill. If this is not the case, the measurement is
made using a correspondingly smaller current.
