Calculation of motor parameters
P0340 = 4
Stator resistance (line-to-line) (entered in Ω)
P0350 = ?
Stator resistance in Ω of the motor which is connected (from line-to-
line). This parameter value also includes the cable resistance.
Rotor resistance (entered in Ω)
P0354 = ?
Defines the rotor resistance of the motor equivalent diagram (phase
value).
Stator leakage inductance (entered in mH)
P0356 = ?
Defines the stator leakage inductance of the motor equivalent diagram
(phase value).
Rotor leakage inductance (entered in mH)
P0358 = ?
Defines the rotor leakage inductance of the motor equivalent diagram
(phase value).
Main inductance (entered in mH)
P0360 = ?
Defines the main (magnetizing) inductance of the motor equivalent
diagram (phase value).
Calculation of motor parameters
P0340 = 3
All of the parameters, dependent on the ECD data are calculated and,
in addition, the controller settings (P0340 = 4).
The motor parameters have been calculated and it is now possible to return to the
