Execution of tuning
b
CAUTION:
Before performing tuning, check the monitor display of the operation panel (FR-DU07)
or parameter unit (FR-PU04/FRPU07) if the inverter is in the state ready for tuning (refer
to Tab. 5-4). When the start command is turned on under V/f control, the motor starts.
When performing PU operation, press the FWD or REV key of the operation panel.
For external operation, turn on the run command (STF signal or STR signal). Tuning starts.
NOTES
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 the STOP/RESET key 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:
–Input signals:
STOP, OH, MRS, RT, CS, RES, STF, and STR
–Output terminal:
RUN, OL, IPF, CA, AM, A1, B1, and C1
Note that the progress status of offline auto tuning is output from AM and CA 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 cir-
cuit power (R/L1, S/L2, T/L3) of the inverter.
Do not perform ON/OFF switching of the second function selection signal (RT) during execu-
tion 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-exci-
tation invalid.
