Description: Sets the integral time of the d-current controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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.
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.
Description: Sets the time constant to calculate the d current DC component difference (combination current) to add to the d
current controller actual value.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: It is not added for p1731 = 0.
Description: Display and connector output for the direct axis voltage setpoint Ud.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
