2 Parameters
2.2 List of parameters
r0396[0...n]

Actual rotor resistance / R_rotor act

VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: PEM, REL, FEM
Min
- [ohm]
Description: Displays the actual rotor/secondary section resistance (phase value).
The parameter is affected by the motor temperature model.
Dependency: Refer to: p0354, p0620
Note: In each case, only the rotor resistance of the active Motor Data Set is included with the rotor temperature of the
thermal motor model.
This parameter is not used for synchronous motors (p0300 = 2xx).
p0397[0...n]

Angle magnetic decoupling maximum angle / Magn decpl max_ang

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: ASM, REL, FEM
Min
0.0 [°]
Description: Maximum angle when calculating the polynomial function to decouple the magnetic flux axes for permanent-magnet
synchronous motors (see p0398, p0399).
p0398[0...n]

Angle magn decoupling (cross saturation) coeff 1 / Magn decoupl C1

VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: ASM, REL, FEM
Min
-10.000000
Description: The magnetic cross coupling of the motor's d and q axes caused by saturation (current-dependent) leads to an angle
offset affecting the axis system d'q'; this decouples the magnetic quantities.
The angle offset can be described as a 3rd order polynomial function of the load current consumed:
phiOffset = f(C1*iq + C3*iq^3)
This parameter is the coefficient C1; it describes the linear load impact effect.
p0399[0...n]

Angle magn decoupling (cross saturation) coeff 3 / Magn decoupl C3

VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: ASM, REL, FEM
Min
-10.000000
Description: The magnetic cross coupling of the motor's d and q axes caused by saturation (current-dependent) leads to an angle
offset affecting the axis system d'q'; this decouples the magnetic quantities.
The angle offset can be described as a 3rd order polynomial function of the load current consumed:
phiOffset = f(C1*iq + C3*iq^3)
This parameter is the coefficient C3; it describes the cubic load impact effect.
