Dependency: Refer to: F07988
Note: The following parameters are influenced for the individual optimization steps:
Bit 01: p0320, p0360, p0362 ... p0369
Bit 02: p0341, p0342
Bit 03: p1400.0, p1458, p1459, p1463, p1470, p1472, p1496
Bit 04: Dependent on p1960
p1960 = 1, 3: p1400.0, p1458, p1459, p1470, p1472, p1496

Description: Sets the rotating measurement.
The rotating measurement is carried out after the next power-on command.
The setting possibilities of the parameter depend on the open-loop/closed-loop control mode (p1300).
p1300 < 20 (V/f open-loop control):
It is not possible to select rotating measurement or speed controller optimization.
p1300 = 20, 22 (encoderless operation):
Only rotating measurement or speed controller optimization can be selected in the encoderless mode.
Value: 0:
1:
3:
Dependency: Before the rotating measurement is carried out, the motor data identification routine (p1900, p1910, r3925) should
have already been done.
When selecting the rotating measurement, the drive data set changeover is suppressed.
Refer to: p1300, p1900, p1959
Danger: For drives with a mechanical system that limits the distance moved, it must be ensured that this is not reached dur-
ing 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).
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.
