p1722[0...n]

Current controller d axis integral time / I_ctrl d-axis Tn

Access level: 4
Can be changed: T, U
Unit group: -
Min:
0.00 [ms]
Description: Sets the integral time of the d-current controller.
p1730[0...n] Isd controller integral component shutdown threshold / Isd ctrl Tn shutd
Access level: 4
Can be changed: T, U
Unit group: -
Min:
30 [%]
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.
p1731[0...n] Isd controller combination current time component / Isd ctr I_combi T1
Access level: 4
Can be changed: T, U
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.
Note
It is not added for p1731 = 0.
