Description: Displays measured stator resistance value (line-to-line) in [Ohms]. This value also includes the cable resistances.
Index: [0] = U_phase
[1] = V_phase
[2] = W_phase
Notice: If the value identified (Rs = stator resistance) does not lie within the range 0.1 % < Rs [p. u.] < 100 % fault message
41 (motor data identification failure) is issued.
P0949 provides further information (fault value = 2 in this case).
Note: This value is measured using P1900 = 2 or 3 (P1910 = 1 or 2) , i.e., identification of all parameters with/without
change.
Description: Displays identified rotor time constant. [msec]
Index: [0] = U_phase
[1] = V_phase
[2] = W_phase
Notice: If the value identified (Tr = rotor time constant) does not lie within the range 10ms < Tr < 5s fault message 41 (motor
data identification failure) is issued.
P0949 provides further information (fault value = 6 in this case).
Description: Displays identified total leakage inductance. [mH]
Index: [0] = U_phase
[1] = V_phase
[2] = W_phase
Notice: If the value identified (Lsigma = leakage inductance) does not lie within the range 5 % < Xsigma [p. u.] < 50 % fault
message 41 (motor data identification failure) is issued.
P0949 provides further information (fault value = 7 in this case).
Description: Displays identified stator inductance. [mH]
Index: [0] = U_phase
[1] = V_phase
[2] = W_phase
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. P0949 provides further information (fault value = 4 in this case).
Description: Displays identified stator inductance. [mH]
Index: [0] = U_phase
[1] = V_phase
[2] = W_phase
Note: See P1915 (identified nominal stator inductance).
