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） "*" changes by Restricted Distribution.
