(3) Execution of tuning
1)When performing PU operation, press
/
of the operation panel.
For external operation, turn on the start command (STF signal or STR signal). Tuning starts.
2)Monitor is displayed on the operation panel (FR-DU07) and parameter unit (FR-PU07/FR-PU04) during tuning as
below.
· Reference: Offline auto tuning time (when the initial value is set)
CAUTION
· Before performing tuning, check the monitor display of the operation panel (FR-DU07) or parameter unit (FR-PU04/FR-
PU07) if the inverter is in the state ready for tuning. (Refer to 2) below) When the start command is turned on under V/F
control, the motor starts.
CAUTION
· When selecting offline auto tuning performed with motor running (
Pr. 96 Auto tuning setting/status
= "101"), caution must be
taken since the motor runs.
· To force tuning to end, use the MRS or RES signal or press
of the operation panel.
(Turning the start signal (STF signal or STR signal) off also ends tuning.)
· During offline auto tuning, only the following I/O signals are valid: (initial value)
· Input signals <valid signal> STOP, OH, MRS, RT, CS, RES, STF, STR
· Output terminal RUN, OL, IPF, FM, AM, A1B1C1
Note that the progress status of offline auto tuning is output in fifteen steps from AM and FM when speed and output
frequency are selected.
· Since the RUN signal turns on when tuning is started, caution is required especially when a sequerence 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 excecuted properly.
· Setting offline auto tuning (
Pr. 96 Auto tuning setting/status
= "1 or 101") will make pre-excitation invalid.

Time
Non-rotation mode (
Pr. 96
= "1")
Approximately 25 to 120s
(Tuning time differs according to the inverter capacity and motor type.)
Rotation mode (
Pr. 96
= "101")
Approximately 40s
(Offline auto tuning time varies with the acceleration and deceleration time
settings as indicated below. Offline auto tuning time = acceleration time +
deceleration time + approx. 30s)
