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.
It takes approximately 9s ∗ until tuning is completed.
(Excitation noise is produced during tuning.)
∗Tuning time differs according to the inverter capacity and motor type.
2) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay. (Refer to page 123)
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
∗1 Refer to page 125 for other settings of Pr. 71.
Execution of tuning
POINT
Before performing tuning, check the monitor display of the operation panel if the inverter is in the status for tuning.
(Refer to 3) below)
1) Set "1" in the X12 signal (Bit11), which gives a control input command through FL remote communication. Then,
change the operation mode to the PU operation mode using
2) Press on the operation panel. Tuning starts.
(When the Network operation mode is selected and "1" is set in the X12 signal (Bit 11), which gives a control input
command through FL remote communication, the inverter output is shutoff. Therefore, inputting a start signal through
FL remote communication does not start tuning in this condition.)
NOTE
To force tuning to end, press
X12 signal is the only valid input/output signal during the offline auto tuning.
Setting "0" in the X12 signal while tuning is being set or performed changes the operation mode to the Network
operation mode forcibly.
Use the X12 signal after setting "0" (stop command) in the forward/reverse rotation command (STF/STR signal) to set
and perform tuning.
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.
3) Monitor is displayed on the operation panel during tuning as below.
