the old inverter’s settings for the primary resistance %R1, leakage reactance %X, no-load current, and rated slip
frequency, and specify those values to the new inverter’s function codes.
Vibration that may occur when the motor's coupling is elastic can be regarded as normal vibration due to the output
voltage pattern applied in tuning. The tuning does not always result in an error; however, run the motor and check its
running state.
4.1.8 Function code basic settings and tuning < 3 >
Driving a motor under vector control without speed sensor (F42* = 5) requires auto-tuning, regardless of the motor type. (Refer
to Figure 4.1 on page 4-1.) (Even driving a Fuji VG motor exclusively designed for vector control requires auto-tuning.)
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" --."

• 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.
• Vector control without speed sensor is not available for MD-mode inverters.
To drive a Fuji VG motor exclusively designed for vector control, configure the following basic function codes, initialize the
motor 1 parameters with the function code (H03=2), and then perform auto-tuning.

Initializing the motor 1 parameters with the function code (H03=2) automatically updates the data of function codes
