Dependency: In 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.
When the power units are connected in parallel with separate, offset motor winding systems (p7003 = 2), then the
compensation of the valve interlocking times should be implemented as Rs adaptation (bit 7 = 1).
Caution: Bit 11: The selection has not been enabled for output filters, with the exception of motor reactors (see p0230)
Notice: It is only permissible to change bit 11 if the drive is switched off.
When selecting bit 11, also for U/f characteristic operation, a standstill measurement must have been performed to
set the necessary current controller for a fast flying restart.
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.
Bit 11 has no influence on flying restart with speed encoder. Depending on the motor, the fast flying restart is suitable
for speeds of maximum 1.5x to 4x the rated motor speed.
Re 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. 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.
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).
