Description: Sets the flux setpoint referred to rated motor flux.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
Description: Sets the flux threshold value for enabling the speed setpoint and the end of magnetizing (r0056.4).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: The parameter only has an influence if the flux actual value reaches the threshold value p1573 more quickly during
magnetizing than the time set in p0346. This is generally the case when selecting fast magnetization (p1401 bit 6).
The parameter has no influence for flying restart (see p1200) and after DC braking (see p1231).
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).
