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 HP rating 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)

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.

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
standard motors so that the best performance cannot be obtained under some controls.
• The motor to be driven is a non-standard motor.
• Cabling between the motor and the inverter is long. (Generally, 66 ft (20 m) or longer)
• A reactor is inserted between the motor and the inverter.
