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.
4.1.9 Function code basic settings < 4 >
Driving a Fuji VG motor exclusively designed for vector control under the vector control with speed sensor (F42* = 6) requires
configuring the following basic function codes. (Refer to Figure 4.1 on page 4-1.)
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" --."

Depending upon the inverter capacity
After the above configuration, initialize motor 1 with the function code (H03 = 2). It automatically updates the data of the
function codes F04*, F05*, P01*, P03*, P06* to P23*, P53* to P56*, and H46.
When accessing the function code P02*, take into account that changing the P02* data automatically updates the data
of the function codes F04*, F05*, P03*, P06* to P23*, P53* to P56*, and H46.
