Use this parameter to set the inductance saturation point.
1-49 Current at Min Inductance for q-axis
Default value: 100% Parameter type: Range (20–200%)
Setup: All setups Conversion index: 0
Data type: Uint16 Change during operation: False
This parameter specifies the saturation curve of the q-inductance values. From 20–100% of this parameter, the inductance is linearly
approximated due to parameter 1-38 q-axis Inductance (Lq) and parameter 1-45 q-axis Inductance Sat. (LqSat). These parameters are
related to the motor nameplate load compensations, the application load type, and the electronic brake function for quick stop/hold of
the motor.
4.2.6 1-5* Load Indep. Setting
Parameters for load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Default value: 100% Parameter type: Range (0–300%)
Setup: All setups Conversion index: 0
Data type: Uint16 Change during operation: True
Use this parameter along with parameter 1-52 Min Speed Normal Magnetising [Hz] to obtain a different thermal load on the motor when
running at low speed. Enter a value that is a percentage of the rated magnetizing current. If the setting is too low, the torque on the
motor shaft may be reduced.

1-52 Min Speed Normal Magnetising [Hz]
Default value: 1.0 Hz Parameter type: Range (0.1–10.0 Hz)
Setup: All setups Conversion index: -1
Data type: Uint16 Change during operation: True
Set the required frequency for normal magnetizing current. Use this parameter along with parameter 1-50 Motor Magnetisation at Zero
Speed.
1-53 Model Shift Frequency
Default value: Size related Parameter type: Range (4.0–65535.0 Hz)
Setup: All setups Conversion index: -1
Data type: Uint16 Change during operation: False
