2.2 List of parameters
Note:
It only makes sense to activate this function if the dynamic response requirements of the speed controller are low.
In order to avoid oscillations, if required, the speed controller parameters should be adapted (increase Tn, reduce
Kp).
Further, the smoothing time of the flux setpoint filter (p1582) should be increased.
Description:
Sets the smoothing time for the flux setpoint.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description:
Displays the smoothed flux setpoint.
The value is referred to the rated motor flux.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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
Description:
Sets the scaling of the precontrol 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.
