No-load current (P06*)
Primary resistance (%R1) (P07*)
Leakage reactance (%X) (P08*)
Rated slip frequency (P12*)
Magnetic saturation factors 1 to 5
Magnetic saturation extension
factors "a" to "c" (P16* to P23*)
%X correction factor 1 and 2
(P53* and P54*)
Tuning the %R1, %X and
rated slip frequency, with
the motor stopped.
Tuning the no-load current
and magnetic saturation
factor, with the motor
running at 50% of the base
frequency twice.
Can rotate the motor,
provided that it is safe.
Note that little load
should be applied
during tuning. Tuning
with load applied
decreases the tuning
accuracy.

The tuning results of motor parameters will be automatically saved into their respective function codes. If P04* tuning is performed,
for instance, the tuning results will be saved into P* codes (Motor 1* parameters).
(2) Preparation of machinery
Perform appropriate preparations on the motor and its load, such as disengaging the coupling from the motor and deactivating the
safety devices.
(3) Tuning
(Tune while the motor is rotating under vector control)
Set function code P04* to "3" and then press the key as shown below.
The inverter waits
for a run command.
Tuning starts with the motor stopped. (Maximum tuning time: Approx. 40 to 75 s.)
Next, the motor is accelerated to approximately 50% of the base frequency and then tuning starts.
Upon completion of measurements, the motor decelerates to a stop.
(Estimated tuning time: Acceleration time + 20 to 75 s + Deceleration time)
After the motor decelerates to a stop in above, tuning continues with the motor stopped.
(Maximum tuning time: Approx. 20 to 35 s.)
The motor is again accelerated to approximately 50% of the base frequency and then tuning starts.
Upon completion of measurements, the motor decelerates to a stop.
(Estimated tuning time: Acceleration time + 20 to 160 s + Deceleration time)
After the motor decelerates to a stop in
above, tuning continues with the motor stopped.
(Maximum tuning time: Approx. 20 to 30 s.)
/
Run command ON
Enter a run command. (The factory default of a run command source is "Keypad" (F02 = 0), so
press the
or key for forward or reverse rotation, respectively. To use the terminal
command FWD or REV as a run command, change the data of function code F02.)
End of tuning
Run command OFF
Press the
key to select the tuning mode.
Use the /
key to set function code P04 to "3."
Turn the run command OFF to complete tuning. (If the run command has been given through the
keypad or the communications link, it automatically turns OFF.)
Upon completion of tuning, the subsequent function code appears.
