2.2 List of parameters
Note: It only makes sense to activate this function if there are low dynamic requirements placed on the speed controller and
there are frequent phases with a low load.
In order to avoid oscillations, if required, the speed controller parameters should be adapted (decrease Kp (p1460,
p1470), increase Tn (p1462, p1472)).
When used without an encoder, flux reduction is not possible for induction motors with closed rotor slots.
p1582[0...n] Flux setpoint smoothing time / Flux setp T_smth
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
4 [ms]
Description: Sets the smoothing time for the flux setpoint.
r1583 Flux setpoint smoothed / Flux setp smooth
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [%]
Description: Displays the smoothed flux setpoint.
The value is referred to the rated motor flux.
p1584[0...n] Field weakening operation flux setpoint smoothing time / Field weak T_smth
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, REL
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
Note: Only the flux setpoint rise is smoothed
p1585[0...n] Flux actual value smoothing time / Flux actVal T_smth
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PMSM, REL
Min
0 [ms]
Description: Sets the smoothing time for the flux actual value.
