Rotating Measurement Selection / Rot Meas Sel - Siemens SINAMICS G150 Manual

Bit 05: p0391, p0392, p0393, p1402.2 only for induction motors
p1960 = 1, 3: p1458, p1459, p1470, p1472, p1496, p1400.0
p1960 = 2, 4: p1458, p1459, p1460, p1462, p1496, p1461, p1463
The identification of the q leakage inductance can only be carried out for unloaded motors or motors with a low load
(load approx. 30% below the rated motor torque). Only then is a current controller adaptation (p0391 ... p0393)
parameterized if the q-leakage inductance under no-load conditions is at least 30 % higher than the total leakage
inductance (p0356, p0358).
Re bit 11 = 1:
Bits 02, 03, 04 no longer have any effect. It makes sense to set bit 11 if the speed controller and it's adaptation were
already set before the measurement.
Re bit 12 = 1:
The selection only has an effect on the measurement p1960 = 1, 2. For the shortened measurement, the magnetizing
current and moment of inertia are determined with a somewhat lower accuracy, the oscillation test is completely
eliminated.
Re bit 13 = 1:
After the measurement has been completed, the system immediately goes into closed-loop speed controlled
operation.

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 (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
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).
