(2) Setting
To perform tuning, set the following parameters about the motor.
(3) Execution of tuning
1)When performing PU operation, press / on the operation panel.
For External operation, turn ON the start command (STF signal or STR signal). Tuning starts.

REMARKS
· To perform offline auto tuning on an IPM motor other than MM-CF, contact your sales representative.
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) Turning ON the start command while
tuning is unavailable starts the motor.
REMARKS
· Satisfy the required inverter start conditions to start offline auto tuning. For example, stop the input of MRS signal.
· To force tuning to end, use the MRS or RES signal or press on 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, 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.
· 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.
· Setting offline auto tuning (Pr. 96 Auto tuning setting/status = "1 or 11") will make pre-excitation invalid.
CAUTION
· 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.
·While Pr. 79 = "7," turn the X12 signal ON to tune in the PU operation mode.
