MICROMASTER 440 Parameter List
190 6SE6400-5BB00-0BP0
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.
P1911 No. of phase to be identified Min: 1
CStat: CT Datatype: U16 Unit: - Def: 3
P-Group: INVERTER Active: Immediately QuickComm.: No Max: 3
Selects maximum number of motor phases to be identified.
r1912[3] Identified stator resistance Min: -
Datatype: Float Unit: Ohm Def: -
P-Group: MOTOR Max: -
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.
r1913[3] Identified rotor time constant Min: -
Datatype: Float Unit: ms Def: -
P-Group: MOTOR Max: -
Displays identified rotor time constant.
Index:
r1913[0] : U_phase
r1913[1] : V_phase
r1913[2] : W_phase
r1914[3] Ident. total leakage inductance Min: -
Datatype: Float Unit: - Def: -
P-Group: MOTOR Max: -
Displays identified total leakage inductance.
Index:
r1914[0] : U_phase
r1914[1] : V_phase
r1914[2] : W_phase
r1915[3] Ident. nom. stator inductance Min: -
Datatype: Float Unit: - Def: -
P-Group: MOTOR Max: -
Displays identified stator inductance.
Index:
r1915[0] : U_phase
r1915[1] : V_phase
r1915[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.
r0949 provides further information (fault value = 4 in this case).
r1916[3] Identified stator inductance 1 Min: -
Datatype: Float Unit: - Def: -
P-Group: MOTOR Max: -
Displays identified stator inductance.
Index:
r1916[0] : U_phase
r1916[1] : V_phase
r1916[2] : W_phase
Details:
See P1915 (identified nominal stator inductance).
