Before operation
(1) Before performing offline auto tuning
Check the following before performing offline auto tuning.
Make sure Advanced magnetic flux vector control or General-purpose magnetic flux vector control (Pr. 80, Pr. 81) is
selected. (Tuning can be performed even under V/F control selected by turning ON X18.)
A motor should be connected. Note that the motor should be at a stop at a tuning start.
The motor capacity should be equal to or one rank lower than the inverter capacity. (note that the capacity should be
0.1kW or more)
The maximum frequency is 120Hz.
A high-slip motor, high-speed motor and special motor cannot be tuned.
As the motor may run slightly, fix the motor securely with a mechanical brake or make sure that there will be no problem
in safety if the motor runs (caution is required especially in elevator). Note that tuning performance is unaffected even if
the motor runs slightly.
Offline auto tuning will not be performed properly if it is performed with a surge voltage suppression filter (FR-ASF-H/FR-
BMF-H) connected between the inverter and motor. Remove it before starting tuning.
(2) Setting
1) Select Advanced magnetic flux vector control or General-purpose magnetic flux vector control. (Refer to page 48)
2) Set "1" or "11" in Pr. 96 Auto tuning setting/status.
When the setting is "1" ....... Tune all motor constants without running the motor.
When the setting is "11"...... Tune motor constants (R1) only without running the motor.
3) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay. (Refer to page 41)
4) Set the rated voltage of motor (initial value is 200V/400V) in Pr. 83 Rated motor voltage and rated motor frequency (initial
value is 60Hz) in Pr. 84 Rated motor frequency.
(For a Japanese standard motor, etc. which has both 50Hz and 60Hz rated values, use it with an initial value (200V/60Hz
or 400V/60Hz).
5) Set Pr. 71 Applied motor according to the motor used.
Mitsubishi standard motor
Mitsubishi high efficiency motor
Mitsubishi constant-torque motor
Other manufacturer's
standard motor
Other manufacturer's
constant-torque motor

Refer to the chapter 4 of the Instruction Manual (applied), for other settings of Pr. 71.

When performing Advanced magnetic flux vector control, set "1" to perform tuning.
It takes approximately 25 to 75s∗ until tuning is completed.
(Excitation noise is produced during tuning.)
∗Tuning time differs according to the inverter capacity and motor type.
When performing General-purpose magnetic flux vector control, set "11" to perform
tuning.
It takes approximately 9s until tuning is completed.
