r1776[0...6] Motor model status signals / MotMod status sig
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:

Max:
-
Factory setting:

Description: Displays the internal status signals of the motor model.
Index 0: Changeover ramp between current and voltage models
Index 1: Changeover ramp for model feedback (only for induction motors without encoder)
Index 2: Changeover ramp for zero frequency range (only for induction motors without encoder)
Index: [0] = Changeover ramp motor model
[1] = Changeover ramp model tracking
[2] = Changeover ramp zero frequency induction motor without encoder
[3...6] = Reserved
p1780[0...n] Motor model adaptation configuration / MotMod adapt conf

Factory setting:
0000 0000 0001 0100 bin
Description: Sets the configuration for the adaptation circuit of the motor model.
Induction motor (ASM):
Rs, Lh and offset compensation.
Bit field: Bit Signal name 1 signal 0 signal FP
01 Select motor model ASM Rs adaptation Yes No -
02 Select motor model ASM Lh adaptation Yes No -
03 Select motor model PMSM kT adaptation Yes No -
04 Select motor model offset adaptation Yes No -
06 Select pole position identification PMSM encoderless Yes No -
07 Select T(valve) with Rs adaptation Yes No -
08 Deselect prelim. meas. of inductance for pole position ident. Yes No -
10 Filter time combination current like current ctrl integral time Yes No -
11 Fast flying restart with voltage model for induction motor Yes No -
12 Start PMSM sensorless with last angle Yes No -
13 Fast pulsed pole position identification Yes No -
14 Delay of the precontrol speed to the motor model Yes No -
15 RESM Q flux model linear active Yes No -
Dependency: In U/f characteristic operating mode only bit 7 is 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
