4.1.8 Function code basic settings and tuning < 3 >
Driving a motor under vector control without speed sensor (F42* = 5) or with speed sensor (F42*=6) requires auto-tuning. (Refer to
Figure 4.1 on page 4-1.)
Configure the function codes listed below according to the motor ratings and your machinery design values. For the motor ratings,
check the ratings printed on the motor's nameplate. For your machinery design values, ask system designers about them.
For details on how to modify the function code data, see Chapter 3, Section 3.4.2 "Setting up function codes -- Menu #1 "Data
Setting" --."

For a test-driving of the motor, increase
values so that they are longer than your machinery
design values. If the specified time is short, the
inverter may not run the motor properly.

• When accessing the function code P02*, take into account that changing the P02* data automatically updates the data
of the function codes P03*, P06* to P23*, P53* to P56*, and H46.
• Specify the rated voltage at base frequency (F05) at the normal value, although the inverter controls the motor keeping
the rated voltage (rated voltage at base frequency) low under vector control without speed sensor. After the auto-tuning,
the inverter automatically reduces the rated voltage at base frequency.

Tuning procedure
(1) Selection of tuning type
Check the machinery conditions and perform the "tuning while the motor is rotating under vector control" (P04*=3). Adjust the
acceleration and deceleration times (F07 and F08) in view of the motor rotation. And specify the rotation direction that matches the
actual rotation direction of the machinery.
If the "tuning while the motor is rotating under vector control (P04*=3)" cannot be selected due to restrictions on the
machinery, refer to "
„
If tuning while the motor is rotating cannot be selected" on page 4-11.

Tuning the no-load current
and magnetic saturation
factor, with the motor
running at 50% of the base
frequency.
Tuning the rated slip
frequency again, 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.
