Parameters
Parameter list
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 Zn, reduce
Kp).
Further, the smoothing time of the flux setpoint filter (p1582) should be increased.
p1582[0...n] Flux setpoint smoothing time / Flux setp T_smth
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
4 [ms]
Description: Sets the smoothing time for the flux setpoint.
r1583 Flux setpoint smoothed / Flux setp smooth
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [%]
Description: Displays the smoothed flux setpoint. The value is referred to the rated motor flux.
p1584[0...n] Flux setpoint smoothing time for field-weakening operation / Flx setp T_smth Fs
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Control
Min
0 [ms]
Description: Sets the smoothing time for the flux setpoint in the field-weakening range
Recommenda- Smoothing should be especially used if there is no regenerative feedback into the line supply. This means that the
tion: DC link voltage can quickly increase in regenerative operation
Note: Only the flux setpoint rise is smoothed
r1589 Field-weakening current, pre-control value / FieldWkCurrPrectrl
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [Aeff]
Description: Displays the pre-control value for the field weakening current.
r1593 Field weakening controller output / Field_ctrl output
VECTOR (n/M) Can be changed: -
Data type: Floating Point
P-Group: Control
Min
- [Aeff]
Description: Displays the output of the field weakening controller.
