Description: Sets the rotating measurement.
The rotating measurement is carried out after the next switch-on command.
The setting possibilities of the parameter depend on the open-loop/closed-loop control mode (p1300).
p1300 < 20 (U/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.
p1300 = 21, 23 (operation with encoder):
Both versions (encoderless and with encoder) of the rotating measurement and speed controller optimization can be
selected.

Dependency: Before the rotating measurement is carried out, the motor data identification routine (p1900, p1910, r3925) should
have already been done.
In the simulation mode, a value of 1 cannot be written into the parameter.
When selecting the rotating measurement, the drive data set changeover is suppressed.
When selecting rotating measurement (with the exception for p1959.13 = 1) the following BICO parameters are set to
standard values, and after the measurement has been completed, are reset back to the original parameter
assignments:
p1020 ... p1023, p1070, p1075, p1138, p1139, p1140 ... p1143, p1155, p1160, p1437, p1476, p1477
Refer to: p1272, p1300, p1900, p1959, p1967, r1968
Refer to: A07987
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: If there is a motor holding brake, it must be open (p1215 = 2).
To permanently accept the determined settings they must be saved in a non-volatile fashion (p0971, p0977).
During the rotating measurement it is not possible to save the parameters (p0971, p0977).
Note: When the rotating measurement is activated, it is not possible to save the parameters (p0971, p0977).
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.
For speed controller optimization with encoder (p1960 = 2, 4), the speed controller for encoderless operation is also
pre-assigned (p1470, p1472).
Depending on whether the speed controller optimization is carried out with or without encoder, different Kp/Tn
adaptations of the speed controller are set (p1464, p1465). If the drive should be controlled with as well as without
speed encoder, then we recommend the use of two drive data sets (p0180). These can then be executed with
different speed controller adaptations.
