NOTES
The motor constants measured once in the offline auto tuning are stored as parameters and
their data are held until the offline auto tuning is performed again.
An instantaneous power failure occurring during tuning will result in a tuning error. After
power is restored, the inverter goes into the normal operation mode. Therefore, when STF
(STR) signal is on, the motor runs in the forward (reverse) rotation.
Any alarm occurring during tuning is handled as in the ordinary mode. Note that if an error
retry has been set, retry is ignored.

CAUTION:
As the motor may run slightly during offline auto tuning, fix the motor securely with
a mechanical brake or make sure that there will be no problem in safety if the motor
runs (caution is required especially in elevator). Note that tuning performance is
unaffected even if the motor runs slightly.
