Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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 limit of the voltage target value.
In steady-state field weakening operation this corresponds to the required output voltage.
The value of 100% refers to p0304.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The output voltage is only limited if the maximum output voltage (r0071) minus the voltage reserve (p1574)
corresponds to a value higher than p1575.
Limiting via p1575 allows the influence of the voltage ripple of the line supply voltage to be eliminated at the operating
point.
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: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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)
