Note1
）
The applicable motor refers to Hitachi standard 3-phase motor (4p). When using other motors, care must be taken to
prevent the rated motor current (50/60Hz) from exceeding the rated output current of the inverter.
Note2
）
The output voltage decreases as the main supply voltage decreases (except when using the AVR function). In any case,
the output voltage cannot exceed the input power supply voltage.
Note3
）
The braking torque via capacitive feedback is the average deceleration torque at the shortest deceleration (stopping from
50/60Hz as indicated). It is not continuous regenerative braking torque. The average deceleration torque varies with
motor loss. This value decreases when operating beyond 50Hz.
Note4
）
To operate the motor beyond 50/60Hz, consult the motor manufacturer for the maximum allowable rotation speed.
Note5
）
To get motor stabilized operation, inverter output Frequency might exceeds preset maximum Freq.(A004/A204) by 2Hz in
maximum.
Note6
）
Derating curve is shown on section 12.3.
Note7
）
Connecting work on RJ45 jack must be done during the inverter power off.
Note8
