Chap. 4 RUNNING THE MOTOR
Performance comparison for drive controls (summary)
Each drive control has advantages and disadvantages. The table below compares the drive controls, showing their relative
performance in each characteristic.
Select the one that shows high performance in the characteristics that are important in your machinery. In rare cases, the
performance shown below may not be obtained due to various conditions including motor characteristics or mechanical rigidity.
The final performance should be determined by adjusting the speed control system or other elements with the inverter being
connected to the machinery (load). If you have any questions, contact your Fuji Electric representative.

4.1.6 Function code basic settings < 1 >
Driving a Fuji general-purpose motor under the V/f control (F42* = 0 or 2) or dynamic torque vector control (F42* = 1) requires
configuring the following basic function codes. (Refer to Figure 4.1 on page 4-1.)
Select Fuji standard 8- or 6-series motors with the function code P99*.
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" --."

(Note) 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.

After the above configuration, initialize motor 1 with the function code (H03 = 2). It automatically updates the motor
parameters P01*, P03*, P06* to P23*, P53* to P56*, and H46.
