SINAMICS G120 Control Units CU240S, Edition 05/2007

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).
