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)
(4) Ending the offline auto tuning
1) Confirm the Pr. 96 value.
• Normal end: "3" or "103" is displayed.
• Error end: "9", "91", "92" or "93" is displayed.
• Forced end: "8" is displayed.
2) When tuning ended normally
For PU operation, press
This operation resets the offline auto tuning and the PU's monitor display returns to the normal indication.
(Without this operation, next operation cannot be started.)
Do not change the Pr. 96 setting after completion of tuning.
If the Pr. 96 setting is changed, tuning data is made invalid.
If the Pr. 96 setting is changed, tuning must be performed again.
3) When tuning was ended due to an error
Offline auto tuning did not end normally. (The motor constants have not been set.) Reset the inverter and start
tuning all over again.
