(3) Monitoring the offline tuning status
When the parameter unit (FR-PU04) is used, the Pr. 96 value is displayed during tuning on the main
monitor as shown below. When the operation panel (FR-DU04) is used, only the same numerical value as
on the PU is displayed:
• Parameter unit (FR-PU04) main monitor
(For inverter trip)
• Operation panel (FR-DU04) display
(For inverter trip)
• Reference: Offline auto tuning time (factory setting)
(4) Ending the offline auto tuning
1) Confirm the Pr. 96 value.
•Normal end: "3" or "103" is displayed.
•Error-activated end: "9", "91", "92" or "93" is displayed.
•Forced end ... "8" is displayed.
2) When tuning ended normally.
For PU operation, press the key. For external operation, switch off the start signal (STF or STR).
This operation resets the offline auto tuning and the PU's monitor display returns to the ordinary indication.
(Without this operation, next operation cannot be done.)
3) When tuning was ended due to an error.
Offline auto tuning did not end normally. (Motor constants have not been set.) Reset the inverter and start
tuning all over again.
4) Error display definitions.
No connection with motor will result in 93 error.

(Offline auto tuning time varies with acceleration and deceleration time settings as
indicated below:
Offline auto tuning time = acceleration time + deceleration time + approximately 30 s)
