Execution of tuning
POINT
Before tuning, check the monitor display of the operation panel or parameter unit (FR-PU04/FR-PU07) to confirm
that the inverter is in the suitable condition for tuning. (Refer to 2) below.) Turning ON the start command in a
tuning-disabled status starts the motor running.
1) To perform tuning for PU operation, press
PU04/FR-PU07).
For External operation, turn ON the run command (STF signal or STR signal). Tuning starts.
(Excitation noise is produced during tuning.)
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
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>
Output terminal
Note that the progress status of offline auto tuning is output in five steps from 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.
NOTE
 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.
 When Pr.79 = "7," turn ON the X12 signal, and tune in the PU operation mode.
2) Monitor is displayed on the operation panel and parameter unit (FR-PU04/FR-PU07) during tuning as below.

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