・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]～[Hb118]
・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.
Minimum frequency setting
Code/Name
Hb130
Minimum frequency,
1st-motor
Hb131
Reduced voltage start
time, 1st-motor
・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.
