Footnotes for the preceding tables and the table on the following page:
*1: The protection method conforms to JEM 1030.
*2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). To use other
motors, care must be taken to prevent the rated motor current (50/60 Hz) from exceeding the
rated output current of the inverter.
*3: The output voltage decreases as the main supply voltage decreases (except for use of the
AVR function). In any case, the output voltage cannot exceed the input power supply
voltage.
*4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer about the maximum
allowable rotation speed.
*5: The braking torque via capacitive feedback is the average deceleration torque at the shortest
deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking
torque. And, the average deceleration torque varies with motor loss. This value decreases
when operating beyond 50 Hz. Note that a braking unit is not included in the inverter. If a
large regenerative torque is required, the optional regenerative braking unit should be used.
*6: The frequency command is the maximum frequency at 9.8V for input voltage 0 to 10 VDC,
or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not convenient for your
application, contact your Hitachi sales representative.
*7: If operating the inverter in an ambient temperature of 40–50
°
C, reduce the carrier frequency
to 2.1 kHz, derate the output current by 80%, and remove the top housing cover. Note that
removing the top cover will nullify the NEMA rating for the inverter housing.
*8: The storage temperature refers to the short-term temperature during transport.
*9: Conforms to the test method specified in JIS C0911 (1984). For the model types excluded in
the standard specifications, contact your Hitachi sales representative.
*10:The input voltage of xxLFU is 230V.
