Siemens SINAMICS G110M Operating Instructions Manual page 341

The motor operates in partial load mode between no-load operation and the rated motor torque.
Depending on p1580, in the partial load range, the converter reduces the flux setpoint linearly
with the torque.
Figure 8-81
The reduced flux in the motor partial load range results in higher efficiency.
