(3) Execution of tuning
1) When performing tuning for PU operation, press of the operation panel or or of the parameter unit
(FR-PU04/FR-PU07).
For external operation, turn ON the run command (STF signal or STR signal). Tuning starts.
(Excitation noise is produced during tuning.)
2) Monitor is displayed on the operation panel and parameter unit (FR-PU04/FR-PU07) during tuning as below.
POINT
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 2) below) When the start command is turned on under V/F
control, the motor starts.
NOTE
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 terminal <valid signal> STF, STR
Output terminal RUN, AM, A, B, C
Note that the progress status of offline auto tuning is output in five 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 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.

REMARKS
It takes approximately 9s until tuning is completed.
The set frequency monitor displayed during the offline auto tuning is 0Hz.
