n maximum
The maximum rotation speed occurring at the
given application. At identifying the magnetization
curve, the motor test suits the section with
weakened field between the nominal point and this
point.

6-13
R stator
Resistance of the stator in %, given from the
nominal parameters of the motor.
The frequency converter measures it with test on
the standing motor.
It effects the parameters of the current control
0,00 - 100,00 5,00 %
6-14
L stator
Stator dispersion inductivity in %.
The frequency converter measures it with test on
the standing motor.
It effects the parameters of the current control.
0,00 - 100,00 10,00 %
6-15
magnetizing
current
The magnetizing current belonging to the nominal
flux, given in % of In. It will be measured by the
frequency converter with the running motor test.
If the motor is to be used with reduced flux, then
prior to performing the running motor test the
nominal voltage and power of the motor has to be
reduced to 80-90% of the clamp data.
When reducing the frequency, the motor runs
more silently, around 50 Hz it runs more quietly,
but the available torque slightly decreases.

current
Specifying the magnetization curve:

fully linear approximation.
60%
→
in the nominal point, 60 % of the curve is
given by the linear component and 40 % by the
non-linear component. The frequency converter
measures here using the running motor test.

exponent of the
magnetising
current
Exponent of the non-linear component of the
magnetization current.
6-16 linearity of the magnetizing current = at
100% it does not make sense.
If both weakening of the field and high dynamic is
required, the magnetization curve of the motor has
to be identified accurately. The more suitable one
is to be selected.

R rotor
correction
Correction of the rotor resistance calculated from
the motor clamp data. If given not right, the same
torque can only be achieved with larger current.
For good dynamic with cold motor, this value is to
be set typically lower by some percent.
The nominal motor data concerns warm motor.

nominal
start time
The time needed for achieving the nominal
rotation speed with the nominal current. Its setting
makes influence to the rotation speed control.
