The table shows the number of poles for normal speed ranges of various motor types. Define motors
designed for other frequencies separately. The motor pole value is always an even number, because
it refers to the total number of poles, not pairs of poles. The frequency converter creates the initial
setting of par.1-39
Motor Frequency
and par.
Motor Nominal Speed
.
This parameter cannot be adjusted while the motor is running.
2.3.5 1-5* Load Indep. Setting
Parameters for setting the load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Range:
Function:
100 %*
[0 - 300 %]
Use this parameter along with par.1-51
Min Speed Normal Magnetising [RPM]
to obtain a different
thermal load on the motor when running at low speed.
Enter a value which is a percentage of the rated magnetizing current. If the setting is too low, the
torque on the motor shaft may be reduced.
1-51 Min Speed Normal Magnetising [RPM]
Range:
Function:
15. RPM*
[10 - 300 RPM]
Set the required speed for normal magnetising current. If the speed is set lower than the motor slip
speed, par.1-50

[0.3 - 10.0 Hz]
Set the required frequency for normal magnetising current. If the frequency is set lower than the
motor slip frequency, par.1-50

[0.0 - 1000.0 V]
Enter the voltage at each frequency point to manually form a U/f characteristic matching the motor.
