・
If the motor capacity[Hb102] and number of poles
[Hb103] are changed, the motor characteristics are set
according to the internal Hitachi table values.
・
For no-rotation auto-tuning, the following variables
are acquired:[Hb110]
～
[Hb114].
・
For rotation auto-tuning, the following variables are
acquired:[Hb110]
～

・
It is possible to input the data obtained from the motor
manufacturer. However, it must also include the data of
the wiring and the like.

If the torque at the time of start-up is not enough, you
can change the settings to raise the lowest frequency.
・
Raise the minimum frequency, if the trip occurs, set a
longer time of reduced voltage start selection.
