Description: Sets the integral-action time of the current controller.
Dependency: Refer to: p1715
Description: Sets the proportional gain of the d-current controller for the lower adaptation current range.
This value is automatically pre-set using p3900 or p0340 when commissioning has been completed.
Note: For p0393 = 100 %, the current controller adaptation is disabled and p1715 is effective over the entire range.
Description: Sets the integral time of the d-current controller.
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.
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.
