In any of the following cases, the default settings may not produce the best results for auto torque boost,
torque calculation monitoring, or auto energy saving, since the standard settings of motor parameters fo
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.
＜Tuning procedure＞
1) Preparation
Referring to the rating plate on the motor, set the following function codes to their nominal ratings:
• F04: Base frequency
• F05: Rated voltage (at Base frequency)
• P02: Rated capacity
• P03: Rated current
2) Selection of Tuning Process
Check the situation of the machine system and choose between "Tuning while the motor is stopped (P04
= 1)" and "Tuning while the motor is running (P04 = 2)." In the case of "Tuning while the motor is running
(P04 = 2)," also adjust the acceleration and deceleration times (F07 and F08) and set the rotation
direction properly so that it matches the actual rotation direction of the machine system.

Motor parameters
subject to Tuning:
Action Choose the process when:
1
Primary resistance (%R1)
Leakage reactance (%X)
Measure %R1 and %X while
the motor is stopped.
The motor cannot be rotated, or
more than 50% of the rated load
would be applied on the motor if
rotated.
2
Primary resistance (%R1)
Leakage reactance (%X)
No-load current
Measure %R1 and %X while
the motor is stopped, and
later no-load current while
the motor is running. (At
50% of the Base frequency).
Even if the motor is rotated, it is
safe and the load applied on the
motor would be no more than 50%
of the rating. (If you do the tuning
with no load, you will get the
highest precision.)
Upon completion of the tuning, the primary resistance %R1 will be automatically saved into P07, the
leakage reactance %X into P08, and the no-load current into P06.
