p1584[0...n] Field weakening operation flux setpoint smoothing time / Field weak T_smth
Access level: 4
Can be changed: U, T
Unit group: -
Min
0 [ms]
Description: Sets the smoothing time for the flux setpoint in the field-weakening range
Recommendation: Smoothing should be especially used if there is no regenerative feedback into the line supply. This means that the
DC link voltage can quickly increase in regenerative operation
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: Only the flux setpoint rise is smoothed
p1586[0...n] Field weakening characteristic scaling / Field weak scal
Access level: 4
Can be changed: U, T
Unit group: -
Min
80.0 [%]
Description: Sets the scaling of the pre-control characteristic for the start of field weakening.
For values above 100 % and for partial load situations, the field weakening starts at higher speeds.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: If the start of field weakening is shifted to lower speeds, then the voltage reserve is increased for partial load
situations.
If the start of field weakening is shifted to higher speeds, the voltage reserve is appropriately reduced so that for fast
load changes, it can be expected that this will have a negative impact on the dynamic performance.
r1589 Field-weakening current pre-control value / I_FieldWeak prectr
Access level: 4
Can be changed: -
Unit group: 6_2
Min
- [Arms]
Description: Displays the pre-control value for the field weakening current.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
p1590[0...n] Flux controller P gain / Flux controller Kp
Access level: 4
Can be changed: U, T
Unit group: -
Min
0.0
Description: Sets the proportional gain for the flux controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: The value is automatically pre-assigned dependent on the motor when the drive system is first commissioned.
When calculating controller parameters (p0340 = 4), this value is re-calculated.
