Siemens G130 List Manual page 457

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
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
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
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
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
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
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
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
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.
