Description: Sets a dynamic voltage reserve.
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 a dynamic voltage reserve.
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: The following applies for a synchronous reluctance motor:
Sets the time constant for reducing the flux setpoint for a load-dependent optimum flux characteristic.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1579
