6.12.4 Online auto tuning (Pr. 95, Pr. 574)
When online auto tuning is selected under advanced magnetic flux vector control, real sensor-
less vector control or vector control, excellent torque accuracy is provided by temperature com-
pensation even if the secondary resistance value of the motor varies with the rise of the motor
temperature.
Start-time online auto tuning (Pr. 95 = 1)
●
By quickly tuning the motor constants at a start, high accuracy operation unaffacted by the
motor temperature and stable operation with high torque down to ultra low speed can be
performed.
●
Make sure advanced magnetic flux vector control (Pr. 80, Pr. 81 ), real sensorless vector
control or vector control (Pr.800 ) is selected.
●
Before performing online auto tuning, perform offline auto tuning (Pr. 96) without fail.
