TEST RUN PROCEDURE
Chap 4
(3) Tuning (For IM)
■ Selection of tuning type
Check the situation of the machine and select “Tuning with the motor stopped (P04* = 1)” or “Tuning with the motor
running (P04* = 2).” For the latter tuning, adjust the acceleration and deceleration times (F07 and F08) and specify
the rotation direction that matches the actual rotation direction of the machine.
If tuning (P04* = 2) with motor running cannot be selected due to the machine, refer to
“
 Countermeasures when tuning for motor rotation cannot be executed”.

Tuning
Select under the following
conditions
1
Tune while the
motor stops.
Primary resistance (%R1)
(P07*)
Leakage reactance (%X)
(P08*)
Rated slip frequency (P12*)
%X correction factor 1
(P53* )
Tuning with the motor stopped.
Cannot rotate the motor.
2
Tune while the
motor is
rotating
No-load current (P06*)
Primary resistance (%R1)
(P07*)
Leakage reactance (%X)
(P08*)
Rated slip frequency (P12*)
%X correction factor 1
(P53* )
magnetic saturation factor 1
to 5 (P16
*
to P20
*
)
Tuning the %R1 and %X, with
the motor stopped.
Tuning the no-load current and
magnetic saturation factor,
with the motor running at 50%
of the base frequency.
Tuning again the rated slip
frequency, with the motor
stopped.
(For vector control, tuning is
executed 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.
5
Tune while the
motor stops.
Primary resistance (%R1)
(P07*)
Leakage reactance (%X)
(P08*)
%X correction factor 1
(P53* )
Tuning with the motor stopped.
Cannot rotate the motor.
The tuning results of motor parameters will be automatically stored into their respective function codes. If tuning by
P04* is performed, the tuning results will be stored into P* codes (Motor 1* parameters).
In the case of tuning by A18*, the tuning data is set to the function code (A* code) of motor 2*.
■ Preparation of machine
In preparation for tuning, remove the motor coupling with the load and deactivate the safety devices before rotation
tuning.
