Description: Sets a dynamic voltage reserve.
Dependency: Refer to: p0500
Note: In the field weakening range, it must be expected that the control dynamic performance is somewhat restricted due
to the limited possibilities of controlling/adjusting the voltage. This can be improved by increasing the voltage
reserve. Increasing the reserve reduces the steady-state maximum output voltage (r0071).
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.
Dependency: Refer to: p0500
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.
