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
Motor Magnetisation at
Zero Speed and par.1-51 Min Speed Normal Magnetising [RPM] are of
no significance.
Use this parameter along with par.1-50
Motor Magnetisation at Zero
Speed. See drawing for par.1-50 Motor Magnetisation at Zero Speed.
1-52 Min Speed Normal Magnetising [Hz]
Range: Function:
0.5 Hz* [0.3 - 10.0 Hz] Set the required frequency for normal magnetising current. If the fre-
quency is set lower than the motor slip frequency, par.1-50
Motor Mag-
netisation at Zero Speed and par.1-51 Min Speed Normal Magnetising
[RPM] are inactive.
Use this parameter along with par.1-50
Motor Magnetisation at Zero
Speed. See drawing for par.1-50 Motor Magnetisation at Zero Speed.
1-6* Load Depend. Setting
Parameters for adjusting the load-dependent motor settings.
1-60 Low Speed Load Compensation
Range: Function:
100 %* [0 - 300 %] Enter the % value to compensate voltage in relation to load when the
motor is running at low speed and obtain the optimum U/f characteristic.
The motor size determines the frequency range within which this pa-
rameter is active.
Motor size Change over
0.25 kW - 7.5 kW < 10 Hz
11 kW - 45 kW < 5 Hz
55 kW - 550 kW < 3-4 Hz
