Description: Threshold for setpoint - actual value tracking of the stator current in the q direction of the current model.
Description: Sets the minimum stator current for separately-excited synchronous motors (FEM).
A negative value means that the field-generating stator current (d-axis) has a negative sign. The valid value is inter-
nally limited to 50% of the rated motor current (p0305).
Description: Sets the speed where a change is made from the inner to the outer cos phi = 1.
If the value that is entered exceeds the rated speed, then a change is made to the inner cos phi = 1 over the com-
plete speed range.
Description: Sets the smoothing time constant for the setpoint of the field-generating current components.
The current filtered in this way is included in the calculation of the cos phi.
Description: Displays the steady-state field generating current setpoint (Id_set).
