Operation selection at power failure and instantaneous power failure
Setting
1) Set "21" in Pr. 96 Auto tuning setting/status.
Tuning is performed without motor running.
2) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay. (Refer to page 119)
3) 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 page 123, for other settings of Pr. 71.
Execution of tuning
POINT
Before performing tuning, check the monitor display of the operation panel or parameter unit (FR-PU04/FR-PU07) if the
inverter is in the status for tuning. (Refer to 2) below)
1) When performing PU operation, press
For External operation, turn ON the start command (STF signal or STR signal). Tuning starts.
(Excitation noise is produced during tuning.)
NOTE
 To force tuning to end, use the MRS or RES signal or press
signal or STR signal) OFF also ends tuning.)
 During offline auto tuning, only the following I/O signals are valid: (initial value)
Input terminal Valid signalSTF, STR
Output terminal RUN, FM, A, B, C
Note that the progress status of offline auto tuning is output in five steps from FM when speed and output frequency
are selected.
 Since the RUN signal turns ON when tuning is started, caution is required especially when a sequence which
releases a mechanical brake by the RUN signal has been designed.
 When executing offline auto tuning, input the run command after switching ON the main circuit power (R/L1, S/L2, T/
L3) of the inverter.
 Do not perform ON/OFF switching of the second function selection signal (RT) during execution of offline auto
tuning. Auto tuning is not executed properly.
2) Monitor is displayed on the operation panel and parameter unit (FR-PU04, FR-PU07) during tuning as below.

(2) Tuning in progress
(3) Normal end
(4) Error end
(when inverter protective function
operation is activated)
REMARKS
It takes approximately 9s until tuning is completed.
