4.1.3 Preparation before running the motor for a test--Setting function code data
Before running the motor, set function code data specified in Table 4.1 to the motor ratings and your
system design values. For the motor, check the rated values printed on the nameplate of the motor.
For our system design values, ask system designers about them.

For details about how to change function code data, refer to Chapter 3, Section 3.4.1 "Setting
up function codes quickly." Refer to the function code H03 in Chapter 5 "FUNCTION CODES"
for the factory default setting of motor parameters. If any of them is different from the default
setting, change the function code data.

For a test-driving of the
motor, increase values
so that they are longer
than your system design
values. If the set time is
short, the inverter may
not start running the
motor.

In any of the following cases, the default settings may not produce the best results for
auto torque boost, torque calculation monitoring, auto energy saving, torque limiter,
automatic deceleration, auto search for idling motor speed, slip compensation, torque
vector, droop control, or overload stop, since the standard settings of motor parameters
for Fuji motors are not applicable. Tune the motor parameters according to the
procedure set forth below.
• The motor to be driven is not a Fuji product or is a non-standard product.
• The cabling between the motor and the inverter is long.
• A reactor is inserted between the motor and the inverter.
A codes are used to specify the data for motor 2. Use them if necessary.

1) Preparation
Referring to the rating plate on the motor, set the following function codes to their nominal
ratings:
• F04 and A02: Base frequency
• F05 and A03: Rated voltage at base frequency
• P02 and A16: Rated capacity
• P03 and A17: Rated current
