Chap. 5 FUNCTION CODES
P02 Motor 1 (Rated capacity)
P02 specifies the rated capacity of the motor. Enter the rated value given on the nameplate of the motor.
Data for P02 Unit Function
kW When P99 (Motor 1 Selection) = 0, 2, 3 or 4
0.01 to 1000
HP When P99 (Motor 1 Selection) = 1
When accessing function code P02 with the keypad, take into account that the P02 data automatically updates the data
of function codes P03, P06 through P23, P53 through P56, and H46.
P03 Motor 1 (Rated current)
P03 specifies the rated current of the motor. Enter the rated value given on the nameplate of the motor.
- Data setting range: 0.00 to 2000 (A)
P04 Motor 1 (Auto-tuning)
The inverter automatically detects the motor parameters and saves them in its internal memory. Basically, it is not
necessary to perform tuning when using a Fuji standard motor with a standard connection with the inverter.
There are three types of auto-tuning as listed below. Select appropriate one considering the limitations in your
equipment and control mode.
Data for P04
Auto-tuning Operation Motor parameters to be tuned
0 Disable N/A N/A
1
Tune while the
motor stops
The inverter performs tuning
while the motor is stopped.
Primary resistance (%R1) (P07)
Leakage reactance (%X) (P08)
Rated slip frequency (P12)
%X correction factors 1 and 2 (P53 and P54)
2
Tune while the
motor is rotating
under V/f control
After tuning while the motor
is stopped, the inverter
performs tuning again, with
the motor running at 50% of
the base frequency.
No-load current (P06)
Primary resistance (%R1) (P07)
Leakage reactance (%X) (P08)
Rated slip frequency (P12)
Magnetic saturation factors 1 to 5 (P16 to P20)
Magnetic saturation extension factors "a" to "c"
(P21 through P23)
%X correction factors 1 and 2 (P53 and P54)
3
Tune while the
motor is rotating
under vector
control
After tuning while the motor
is stopped, the inverter
performs tuning, with the
motor running at 50% of the
base frequency twice.
No-load current (P06)
Primary resistance (%R1) (P07)
Leakage reactance (%X) (P08)
Rated slip frequency (P12)
Magnetic saturation factors 1 to 5 (P16 to P20)
Magnetic saturation extension factors "a" to "c"
(P21 to P23)
%X correction factors 1 and 2 (P53 and P54)
For details of auto-tuning, refer to Chapter 4, Section 4.1 "Running the Motor for a Test."
In any of the following cases, perform auto-tuning since the motor parameters are different from those of Fuji
standard motors so that the best performance cannot be obtained under some controls.
• The motor to be driven is a non-Fuji motor or a non-standard motor.
• Cabling between the motor and the inverter is long. (Generally, 20 m or longer)
• A reactor is inserted between the motor and the inverter.
