 Tuning procedure
(1) Selection of tuning type
Check the situation of the machinery and select "Tuning with the motor running (P04
*
= 3)." 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 machinery.
If "Tuning with the motor running (P04
*
= 3)" cannot be selected due to a restriction of the facilities, refer
to "
 When tuning with the motor running cannot be performed."

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.
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 procedure (tuning while the motor is running for vector control)
1) Set function code P04
*
to "3" and press the
key. (The blinking of 3 on the LED monitor will slow
down.)
