Parameter
Execution of tuning
CAUTION:
E
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 the start
command is turned on under V/F control, the motor starts.
When performing tuning or PU operation, press the RUN key of the operation panel or the FWD or REV
key of the parameter unit (FR-PU04/FR-PU07).
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/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: (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 in eight steps 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 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 autotuning. Auto tuning is not executed properly.
Do not connect a surge voltage suppression filter (FFR-DT) between the inverter and motor.
