Function:
Use this parameter along with par. 1-51
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.
Function:
Set the required speed for normal magnetising current. If the speed is set lower than the motor slip

Use this parameter along with par. 1-50
par. 1-50 Motor Magnetisation at Zero Speed
Function:
Set the required frequency for normal magnetising current. If the frequency is set lower than the

par. 1-50 Motor Magnetisation at Zero Speed
Function:
Flux Model shift
Enter the frequency value for shift between two models for determining motor speed. Choose the
value based on settings in par. 1-00 Configuration Mode
are two options: shift between Flux model 1 and Flux model 2; or shift between Variable Current
mode and Flux model 2. This parameter is available for FC 302 only.
This parameter cannot be adjusted while the motor is running.
