2.2 List of parameters
p1727[0...n] Quadrature arm decoupling at voltage limit scaling / TrnsvDecplVmaxScal
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.0 [%]
Description: Sets the scaling of quadrature arm decoupling when the voltage limit is reached.
r1728

De-coupling voltage in-line axis / U_dir-axis_decoupl

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [Vrms]
Description: Displays the actual output of the quadrature channel de-coupling for the d axis.
r1729

De-coupling voltage quadrature axis / U_quad_decoupl

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [Vrms]
Description: Displays the actual output of the quadrature channel de-coupling for the q axis.
p1730[0...n] Isd controller integral component shutdown threshold / Isd ctrl Tn shutd
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL, FEM
Min
30 [%]
Description: Sets the speed threshold for deactivating the integral component of the Isd controller.
The d current controller is only effective as P controller for speeds greater than the threshold value. Instead of the
integral component, the quadrature arm decoupling is effective.
Warning: For settings above 80%, the d current controller is active up to the field weakening limit. When operated at the
voltage limit, this can result in an unstable behavior. In order to avoid this, the dynamic voltage reserve p1574 should
be increased.
Note: The parameter value is referred to the synchronous rated motor speed.
p1731[0...n] Isd controller combination current time component / Isd ctr I_combi T1
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL, FEM
Min
0.00 [ms]
Description: Sets the time constant to calculate the d current DC component difference (combination current) to add to the d
current controller actual value.
Note: It is not added for p1731 = 0.
