Siemens SINAMICS G120XA Operating Instructions Manual page 531

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.
The following applies for a synchronous reluctance motor:
The scaling allows the flux setpoint to be adapted when operating with load-dependent optimum flux characteristic or
with constant flux setpoint.

(PM330)
Can be changed: T, U

50.0 [%]
Description: Sets the flux setpoint referred to rated motor flux.
The following applies for a synchronous reluctance motor:
Scaling the flux setpoint.
Dependency: See also: p0500
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.
The following applies for a synchronous reluctance motor:
The scaling allows the flux setpoint to be adapted when operating with load-dependent optimum flux characteristic or
with constant flux setpoint.
p1574[0...n] Voltage reserve dynamic / U_reserve dyn
Access level: 3
Can be changed: T, U
Unit group: 5_1
Min:
0.0 [Vrms]
Description: Sets a dynamic voltage reserve.
Dependency: See also: 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).
