N O T I C E
Run an AMA to set the value of this parameter. Edit the value manually only when the application requires a value other than
determined by AMA.
Enter the q-axis inductance saturation point. The drive uses this value to optimize the performance of IPM motors. Select the value
that matches the point where the inductance equals the average value of parameter 1-38 q-axis Inductance (Lq) and parameter 1-45
q-axis Inductance Sat. (LqSat), as a percentage of nominal current.

N O T I C E
The following parameter is only available in FC 302:
Parameter 1-53 Model Shift Frequency
This parameter group contains parameters related to:
Motor nameplate load compensations.
Application load type.
Electronic brake function for quick stop/hold of the motor.
Parameter 1-50 Motor Magnetization at Zero Speed

Parameter type: Range, 0 - 300%
Change during operation: True
N O T I C E
Parameter 1-50 Motor Magnetisation at Zero Speed has no effect when parameter 1-10 Motor Construction = [1] PM, nonsalient SPM.
Use this parameter along with parameter 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.
