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 adjustable frequency drive
creates the initial setting of par.1-39
Motor Poles based on par.1-23 Motor
Frequency and par.1-25 Motor Nominal Speed.
This parameter cannot be adjusted while the motor is running.
1-5* Load Indep. Setting
Parameters for setting the load-independent motor settings.
1-50 Motor Magnetization at Zero Speed
Range: Function:
100 %* [0 - 300 %] Use this parameter along with par.1-51
Min Speed Normal Magnetizing
[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.

[10 - 300 RPM] Set the required speed for normal magnetizing current. If the speed is
set lower than the motor slip speed, par.1-50
Motor Magnetization at
Zero Speed and par.1-51 Min Speed Normal Magnetizing [RPM] are of
no significance.
Use this parameter along with par.1-50
Motor Magnetization at Zero
Speed. See drawing for par.1-50 Motor Magnetization at Zero Speed.
