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 P08, P10, P12, and H46.
The motor rating should be specified properly when performing auto-torque boost, torque
calculation monitoring, auto energy saving, torque limiting, automatic deceleration
(anti-regenerative control), auto search for idling motor speed, or slip compensation.
In any of the following cases, the full control performance may not be obtained from the
inverter because the motor parameters differ from the factory defaults, so perform
auto-tuning.
• The motor to be driven is not a Fuji product or is a non-standard product.
• The wiring distance between the inverter and the motor is too long (generally 20 m or
more).
• A reactor is inserted between the inverter and the motor.
Refer to Section 5.7.9 "Function code basic settings and tuning < 2 >."
