Dependency: In U/f characteristic operating mode only bit 7 is relevant.
For active motor model feedback (see p1784), the Lh adaptation is internally deactivated automatically.
Note: ASM: Induction motor
PEM: Permanent magnet synchronous motor
When selecting the compensation of the valve interlocking via Rs (bit 7), the compensation in the gating unit is de-
activated and is instead taken into account in the motor model.
In order that the correction values of the Rs, Lh and kT adaptation (selected using Bit 0 ... Bit 2) are correctly
accepted when changing over the drive data set, a dedicated motor number must be entered into p0826 for each
different motor.
p1784[0...n] Motor model feedback scaling / MotMod fdbk scal
Access level: 4
Can be changed: U, T
Units group: -
Min
0.0 [%]
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.
p1785[0...n] Motor model Lh adaptation Kp / MotMod Lh Kp
Access level: 4
Can be changed: U, T
Units group: -
Min
0.000
Description: Sets the proportional gain for the Lh adaptation of the motor model for an induction motor (ASM).
p1786[0...n] Motor model Lh adaptation integral time / MotMod Lh Tn
Access level: 4
Can be changed: U, T
Units group: -
Min
10 [ms]
Description: Sets the integral time for the Lh adaptation of the motor model for an induction motor (ASM).
r1787[0...n] Motor model Lh adaptation corrective value / MotMod Lh corr
Access level: 4
Can be changed: -
Units group: -
Min
- [mH]
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.
