(1) Before performing offline auto tuning
POINT
This function is made valid only when a value other than "9999" is set in Pr. 80 and general-purpose magnetic
flux vector control is selected.
You can copy the offline auto tuning data (motor constants) to another inverter with the PU (FR-PU07).
Even when motors (other manufacturer's motor, SF-JRC, etc.) other than Mitsubishi standard motor, high
efficiency motor (SF-JR, SF-HR 0.2kW or more), and Mitsubishi constant-torque motor (SF-JRCA SF-HRCA
four-pole 0.4kW to 7.5kW) are used or the wiring length is long, using the offline auto tuning function runs the
motor with the optimum operating characteristics.
Tuning is enabled even when a load is connected to the motor.
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.
Reading/writing/copy of motor constants (Pr. 90) and motor excitation current tuned by offline auto tuning are
enabled.
The offline auto tuning status can be monitored with the operation panel and PU (FR-PU04/FR-PU07).
Do not connect a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) between the inverter and motor.
Check the following before performing offline auto tuning.
Make sure general-purpose magnetic flux vector control (Pr. 80) 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-ASFH/FR-
BMF-H) connected between the inverter and motor. Remove it before starting tuning.
(2) Setting
1) Select general-purpose magnetic flux vector control (Refer to page 70).
2) Set "11" in Pr. 96 Auto tuning setting/status.
Tuning motor constants (R1) only without running the motor. (It takes approximately 9s until tuning is completed.)
3) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay. (Refer to page 95)
4) Set the rated voltage of motor (initial value is 200V/400V) in Pr. 83 Motor rated voltage and rated motor frequency (initial
value is 50Hz) 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.
