DANGER
For drives with a mechanical system that limits the distance moved, it must be ensured that this is not reached during
the rotating measurement. If this is not the case, then it is not permissible that the measurement is carried out.
NOTICE
To permanently accept the determined settings they must be saved in a non-volatile fashion (p0971).
During the rotating measurement it is not possible to save the parameter (p0971).
Note
When the rotating measurement is activated, it is not possible to save the parameters (p0971).
Parameter changes are automatically made for the rotating measurement (e.g. p1120); this is the reason that up to the
end of the measurement, and if no faults are present, no manual changes should be made.
The ramp-up and ramp-down times (p1120, p1121) are limited, for the rotating measurement, to 900 s.

Description: Sets the speed to determine the saturation characteristic.
The percentage value is referred to p0310 (rated motor frequency).
Dependency: See also: p0310, p1959
See also: F07983
Note
The saturation characteristics should be determined at an operating point with the lowest possible load.
