p1730[0...n] Isd controller integral component shutdown threshold / Isd ctrl Tn shutd
Access level: 4
Can be changed: U, T
Unit group: -
Min
30 [%]
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.
p1731[0...n] Isd controller combination current time component / Isd ctr I_combi T1
Access level: 4
Can be changed: U, T
Unit group: -
Min
0.00 [ms]
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.
r1732[0...1] CO: Direct-axis voltage setpoint / Direct U set

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)
r1733[0...1] CO: Quadrature-axis voltage setpoint / Quad U set
Access level: 3
Can be changed: -
Unit group: 5_1
Min
- [Vrms]
Description: Display and connector output for the quadrature axis voltage setpoint Uq.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
