Based on its thermal motor model, the converter continually determines - for the actual
operating point of the motor - the interdependency between e󹪟ciency and 󹪞ux. The
converter then sets the 󹪞ux to achieve the optimum e󹪟ciency.

Depending on the motor operating point, the converter either decreases or increases the 󹪞ux
in partial load operation of the motor.

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 󹪞ux
setpoint linearly with the torque.
