2.2 List of parameters
Description: Sets the scaling for model fault feedback.
Note: Feeding back the measured model fault to the model states increases the control stability and makes the motor
model rugged against parameter errors.
When feedback is selected (p1784 > 0), Lh adaptation is not effective.
Description: Sets the proportional gain for the Lh adaptation of the motor model for an induction motor (ASM).
Description: Sets the integral time for the Lh adaptation of the motor model for an induction motor (ASM).
Description: Displays the corrective value for the Lh adaptation of the motor model for an induction motor (ASM).
Dependency: Refer to: p0826, p1780
Note: The adaptation result is reset if the magnetizing inductance of the induction motor is changed (p0360, r0382). This
also happens when changing over the data set if a different motor is not being used (p0826).
The display of the inactive data sets is only updated when changing over the data set.
Description: Sets the pulse frequency for the converter.
This parameter is pre-set to the rated converter value when the drive is first commissioned.
Dependency: Refer to: p0230
Note: The maximum and minimum possible pulse frequency is also determined by the power unit being used (minimum
pulse frequency: 2 kHz or 4 kHz).
When the pulse frequency is increased, depending on the particular power unit, the maximum output current can be
reduced (derating, refer to r0067).
