r1778 Motor model flux angle difference / MotMod ang. diff.
Access level: 4
Can be changed: -
Units group: -
Min
- [°]
Description: Displays the difference between the motor model flux angle and the transformation angle.
Dependency: A setting for smoothing the display can be made using p1754.
p1780[0...n] Motor model adaptation configuration / MotMod adapt conf
Access level: 4
Can be changed: U, T
Units group: -
Min
-
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM): Rs, Lh, and offset compensation.
Permanent magnet synchronous motor (PEM): kT
Bit field: Bit Signal name
01 Select motor model ASM Rs adaptation
02 Select motor model ASM Lh adaptation
03 Select motor model PEM kT adaptation
04 Select motor model offset adaptation
06 Select pole position identification PEM
encoderless
07 Select T(valve) with Rs adaptation
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 / Mod_FB_scal
Access level: 3
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.
The model feedback is only effective for encoderless operation of the ASM.
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).
