Dependency: In U/f characteristic operating mode only bit 7 is relevant.
For active motor model feedback (see p1784), the Lh adaptation is internally de-activated automatically.
Note: ASM: Induction motor
PMSM: 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.
For bit 12 (only for synchronous motors and bit 6 = 1):
The pole position identification is only carried out after power on and after the motor has coasted down. The switch-
off speed p1226 should be as low as possible. If the power unit is switched off when the motor is stationary, then the
next time that the power unit is switched on, the old angle is used as starting value. The precondition applies that
while the power unit is switched off the motor does not rotate.
The duration of the pole position identification is shortened using bit 13. As a consequence, the pole wheel angle
error can be slightly greater.
p1784[0...n] Motor model feedback scaling / MotMod fdbk scal
Access level: 4
Can be changed: U, T
Unit group: -
Min
0.0 [%]
Description: Sets the scaling for model fault feedback.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
