Offline auto tuning (Pr. 80 to Pr. 96)
(1) Parameter setting
• Select Pr. 851 "number of encoder pulses" and Pr. 852 "encoder rotation direction" (Refer to page 10.)
(It is not necessary to select when using the motor without encoder.)
• Select Pr. 80 (Pr. 453) "motor capacity" and Pr. 81 (Pr. 454) "number of motor poles".
• Refer to the parameter details to set the parameters below.
1) Set "1" or "101" in Pr. 96 (Pr. 463)
•When the setting is "1" . . . . .tuning performed without motor running
•When the setting is "101" . . .tuning performed with motor running
2) Set Pr. 9 (Pr. 452) "electronic thermal O/L relay".
When using the external thermal, change the Pr. 9 (Pr. 452) setting back to "0" after offline auto tuning. The
electronic thermal function is made invalid. Set "0" in Pr. 876 if the external thermal relay is not used.
3) Set the rated motor voltage (V) in Pr. 83 (Pr. 456).
4) Set the rated motor frequency (Hz) in Pr. 84 (Pr. 457).
5) Select the motor in Pr. 71 (Pr. 450).

(2) Tuning command
After setting the above parameters, press
(For external operation, turn on the run command (STF, STR).)
REMARKS
• To force tuning to end, use the MRS or RES signal or press
• Excitation noise is produced during tuning.
• When executing offline auto tuning, input the run command after switching on the main circuit power (R, S, T) of the inverter.
(3) Monitoring during execution
When the parameter unit (FR-PU04V) is used, the Pr. 96 (Pr. 463) value is displayed during tuning on the main
monitor as shown on the next page. When the operation panel (FR-DU04-

REMARKS
• Offline auto tuning time (factory setting)
1: No-rotation mode: Approx. 25s
2: Rotation mode: Approx. 40s
(Offline auto tuning time varies with the acceleration and deceleration time settings as indicated below.
Offline auto tuning time = acceleration time + deceleration time + approx. 30s)
