Description: Displays the limit value for the integral component of the Isd current controller.
Description: Sets the scaling of the quadrature arm decoupling
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 effec-
tive in the complete speed control range.
For the closed-loop control of synchronous motors, this parameter is used to scale the current controller de-cou-
pling.
Description: Sets the scaling of quadrature arm decoupling when the voltage limit is reached.
Description: Displays the actual output of the quadrature channel de-coupling for the d axis.
Description: Displays the actual output of the quadrature channel de-coupling for the q axis.
