PM Motor Tuning (22-21)
WARNING!
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.
(1) Please set 00-00=5 and then set 22-21=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) When 22-21=1, press the enter key to go to the PM motor tuning screen. The keypad will
display the message of “IPrdy” (Ready to Tune), press run to start the PM motor tuning. The
keypad will display the “IPtun” message during auto-tune.
(3) 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).
Note：
If inverter already performed motor auto tuning, it is not required to perform motor tuning
again when re-powered up.
PM SLV acceleration time (22-23)
PM SLV acceleration time is the acceleration time from static to I/F Mode Start Frequency Switching
Point (22-11).
Note：
If occur error or vibration in PMSLV mode. Suggest to increase or decrease acceleration time. Please
adjust acceleration time by different application.
Initial position detection of PM motor (22-25)
Use for PMSLV control mode.
When 22-25=1, inverter will detect the initial position of motor rotator while motor is starting to run.
It can prevent the motor reverse the stator.
When 22-25=0, detection function is disabled, inverter will not perform the detection while motor is
running. If the motor does not allow to run, please use this mode.
