Notice: P1910 can't be changed while the motoridentification with P1900 is active (P1900 = 2 or 3).
When the identification is finished P1910 is set to 0.
When choosing the setting for measurement, observe the following:
1. "with parameter change"
means that the values are actually adopted as Pxxxx parameter settings (see common settings above) and ap-
plied to the controller as well as being shown in the read-only parameters below.
2. "without parameter change"
means that the values are only displayed, i.e. shown for checking purposes in the read-only parameters r1912
(identified stator resistance), r1913 (identified rotor time constant), r1914 (ident. total leakage reactance),
r1915/r1916/r1917/r1918/r1919 (identified nominal stator reactance/identified stator reactance 1 to 4), r1925 (IG-
BT on-state voltage) and r1926 (identified gating unit dead time). The values are not applied to the controller.
Note: Before selecting motor data identification, "Quick commissioning" has to be performed in advance.
Since the cable length of the applications differ in a wide range the preset resistor P0352 is only a rough estimation.
Better results of the motor identification can be achieved by specifing the cable resistor before the start of the motor
identification by measuring/calculating.
Once enabled (P1910 > 0), A0541 generates a warning that the next ON command will initiate measurement of
motor parameters.
Communications - both via USS as well as via the Fieldbus - are interrupted for the time that it takes to make inter-
nal calculations.
This can result in the following error messages at the connected SIMATIC S7 control (communications via fieldbus):
• Parameter fault 30
• Drive fault 70
• Drive fault 75
When using STARTER (USS) to commission the drive system, data cannot be entered while these calculations are
being made.
The faults can be acknowledged as soon as the calculations have been completed in the frequency inverter. These
calculations can take up to one minute to complete.
