Motor model adaptation configuration / MotMod adapt conf
G120X_DP (PM330),
Access level: 3
G120X_PN (PM330),
Can be changed: T, U
G120X_USS (PM330)
Unit group: -
Min:
-
Description:
Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM):
Rs, Lh and offset compensation.
Bit field:
Bit
01
02
04
07
10
11
Dependency:
In the U/f characteristic operating mode, only bit 7 and bit 11 are relevant.
For active motor model feedback (see p1784), the Lh adaptation is internally deactivated automatically.
Note
When selecting the compensation of the valve interlocking via Rs (bit 7), the compensation in the gating unit is
deactivated and is instead taken into account in the motor model.
In order that the correction values of the Rs and Lh adaptation (selected using bit 0 ... bit 1) are correctly accepted when
changing over the drive data set, a dedicated motor number must be entered into p0826 for each different motor.
ASM: Induction motor
RESM: synchronous reluctance motor

Motor model feedback scaling / MotMod fdbk scal
Access level: 4
Can be changed: T, U
Unit 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.

Motor model Lh adaptation Kp / MotMod Lh Kp
Access level: 4
Can be changed: T, U
Unit group: -
Min:
0.000
Description:
Sets the proportional gain for the Lh adaptation of the motor model for an induction motor (ASM).
