Description: Sets the efficiency optimization.
When optimizing the efficiency, the flux setpoint of the closed-loop control is adapted as a function of the load.
For p1580 = 100 %, under no-load operating conditions, the flux setpoint is reduced to 50 % of the rated motor flux.
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.
Description: Displays the smoothed flux setpoint.
The value is referred to the rated motor flux.
Description: Sets the smoothing time for the flux setpoint in the field-weakening range
Recommend.: 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
