SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the proportional gain of the current controller.
This value is automatically pre-set using p3900 or p0340 when commissioning has been completed.
Description: Sets the integral-action time of the current controller.
Dependency: Refer to: p1715
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 volt-
age 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 cur-
rent controller actual value. The additional input is de-activated with p1731 = 0.
