Operation selection at power failure
Execution of tuning
b
CAUTION:
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
Tab. 6-13).
When performing tuning or PU operation, press the RUN key of the operation panel.
For external operation, turn on the run command (STF signal or STR signal). Tuning starts.
NOTES
To force tuning to end, use the MRS or RES signal or press the STOP 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: (initial value)
– Input terminal <valid signal> MRS, RES, STF, STR
– Output terminal RUN, AM, A, B, C
Note that the progress status of offline auto tuning is output from AM 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 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.
