2.2 List of parameters
Note:
This parameter is ineffective for sensorless vector control. In this case, p1727 is always used. If p1726 is set to 0,
then the quadrature de-coupling is de-activated. The integral component of the Isd current controller remains
effective in the complete speed control range.
For the closed-loop control of synchronous motors, this parameter is used to scale the current controller de-coupling.
Description:
Sets the scaling of quadrature arm decoupling when the voltage limit is reached.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Description:
Displays the actual output of the quadrature channel de-coupling for the d axis.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Description:
Displays the actual output of the quadrature channel de-coupling for the q axis.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Description:
Sets the speed threshold for de-activating 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.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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.
