Siemens 440 manual P1911 No. of phase to be identified, R19123 Identified stator resistance

Parameter Description Issue 01/06

Notice:

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 applied 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 (IGBT on-state voltage) and r1926 (identified gating unit dead time). The values are not applied to the controller.

Displays measured stator resistance value (line-to-line) in [Ohms]

Index:

r1912[0] : U_phase

r1912[1] : V_phase

r1912[2] : W_phase

Note:

This value is measured using P1910 = 1 or 2 , i.e., identification of all parameters with/without change.

Notice:

If the value identified (Ls = stator inductance) does not lie within the range 50 % < Xs [p. u.] < 500 % fault message 41 (motor data identification failure) is issued.

r0949 provides further information (fault value = 4 in this case).
