(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 is used, the same value
as on the PU is only displayed:
• Operation panel display

• Parameter unit (FR-PU04) main monitor

• Reference: Offline auto tuning time (factory setting) is about 10s.
(4) Ending the offline auto tuning
1) Confirm the Pr. 96 value.
• Normal end: "3" is displayed.
• Abnormal end: "9", "91", "92" or "93" is displayed.
• Forced end: "8" is displayed.
2) When tuning ended normally
For PU operation or combined operation 2, press the
operation or combined operation 1, switch off the start signal (STF or STR) once.
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.)
Do not change the Pr.96 setting after completion of tuning (3). 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.
