22-18: Flux-Weakening Limit
If the motor's maximum rotation speed (22-05) is set to be higher than the motor's rated rotation speed (22-04),
it will automatically start the flux-weakening control. It is set to limit the maximum flux-weakening energy and
the unit is the percentage of motor rated current.
22-20: Offset Angle of the Magnetic Pole and PG Origin
Magnetic pole alignment offset value is stored in this parameter after tuning.
22-21: PM Motor Tuning
Sudden start: the inverter and motor may start unexpectedly during Auto-Tuning, which could result in death or
serious injury. Make sure the area surrounding of the motor and load are clear before proceeding with Auto-Tuning.
Warning
Démarrage inopiné : l'inverseur et le moteur peuvent démarrer de manière inopinée pendant l'Auto-tuning,
avec des risques de blessures graves, voire fatales. S'assurer que la zone autour du moteur et la charge sont
dégagées avant de procéder à l'Auto-tuning.
Electric Shock Hazard
High voltage is supplied to the motor when performing an auto-tune, even when the motor is stopped, which
Warning
could result in death or serious injury. Do not touch the motor when performing magnetic pole realignment until
the auto-tuning procedure is completed.
Risque d'électrocution
Le moteur est alimenté à haute tension lors d'un Auto-tuning, et ce même lorsqu'il est coupé. D'où un risque
de blessures graves, voire fatales. Eviter tout contact avec le moteur pendant l'exécution du réalignement des
pôles magnétiques et jusqu'à l'achèvement de la procédure d'Auto-tuning.
Holding Brake
Do not perform a magnetic pole realignment auto-tuning procedure when the motor is connected to a brake this
Warning
may result in incorrect motor data calculation.
Frein de maintien
Ne pas effectuer la procédure Auto-tuning de réalignement des pôles magnétiques lorsque le moteur est con-
necté à un frein, car cela pourrait donner lieu à un mauvais calcul des données du moteur.
Disconnect the motor and the load and confirm that the motor can freely run.
1. Before selecting PM motor tuning, enter the motor data (22-00) - (22-06) according to the motor nameplate
and the number of encoder pulses (20-27).
2. a) Use parameter 22-21 to select tuning mode.
b) Next press the enter key to go to the PM motor tuning screen. The keypad will display the message of
"IPrdy" (Ready to Tune).
c) Press run to start the PM motor tuning. The keypad will display the "IPtun" message during auto-tune.
d) If the motor is successfully tuned, the message of "IPEnd " will be displayed. If auto-tune is aborted with
the stop key, the operator will display the message of " IPbrd "(PM motor tuning aborted).
Notes:
1. Perform a magnetic pole alignment auto-tune before adjusting the speed loop.
2. It is not required to perform a magnetic pole alignment auto-tune each time the inverter is powered up.
22-22: Fault History of PM Motor Tuning
Parameter 22-22 shows the PM motor tuning fault history. If PM motor tuning has failed, the "IPErr" message is
shown on the keypad (PM motor tuning failure) ; Refer to chapter 10 for the possible error causes and trouble
shooting.
