Description
Motor Identification
When set to 1, the drive immediately carries out a non-
rotating autotune to measure the motor parameters for
optimum control and efficiency. Following completion of
the autotune, the parameter automatically returns to 0.
Note:
This function cannot be activated by using the drivesCon-
nect software! When operating with Vector Control (P6-01
= 1) this parameter must be set to the motor nameplate
power factor (P7-02) before performing auto tune.
Power factor cos ϕ of the motor
When operating with Vector Control (P7-02 = 1) this param-
eter must be set to the motor nameplate power factor.
Stator resistance of the motor
For induction and PM motors: phase to phase resistance
value [Rs] in Ohms
Rotor resistance of the motor
For induction motors: phase to phase resistance value [Rr]
in Ohms
Stator inductance of the motor, torque producing
For induction motors: Phase to phase inductance value in
Henry [H}
For PM-Motors: phase d-axis inductance value [Lsd] in
Henry [H]
Stator inductance of the motor, magnetizing
For PM-Motors: phase d-axis inductance value [Lsd] in
Henry [H]
