Faktor Feldschwächung (dr.20) = 1

For an optimum motor adaption, this factor may have to be modified .
The flux
reduction is well parametrised, if for every operating point a voltage reserve of approx. 3...10% is
available. I.e., the modulation factor (ru.42) should be (dr.18) ca. 90...97% under nominal
load at the field wea

kening speed.
7.5.2.2.3 Magnetisation
current adaption
For large motors, the automatic calculation of the magnetising current occasionally returns values that are too
large. This value can be reduced by adjusting the
parameter "factor flux adaption" (
dr.19).
Whether the automatically calculated magnetising current is too large, can be tested by accelerating the drive
to the field weakening speed (
dr.18) in speed-controlled operation with no load. At this speed, the average va-
lue of the modulation factor should not exceed 90%. If this value is exceeded, the factor "
factor flux adaption"
(dr.19) should be reduced.
7.5.2.3
Vector controlled operation with motor model (with encoder feedback)
The vector controlled operation with motor model is possible only if the electrical characteristic data of a motor
are known. For this operating mode, the motor model calculation must be activated in parameter dS.04.

7.5.2.3.1
Electrical parameters (equivalent circuit data) of the motor
The electrical characteristic data of the motor must be known for vector controlled operation with motor model.
The parameters DASM stator resistance (dr.06), DASM leakage inductance (dr.07) and DASM rotor resistance
(dr.08) can be taken from a motor data sheet or they can be automatically determined by the KEB COMBIVERT
using the motor
identification. For motors with high power, the resistances are very small (a few mΩ). This can
lead to error in the automatically identification. For these motor, it may be sensible to use the
value from the
