Note 10: The storage temperature refers to the short-term temperature during transport.
Note 11: Conforms to the test method specified in JIS C0911 (1984). For the model
Note 12: The input voltage of xxLFU is 230V.
The protection method conforms to JEM 1030.
The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When
using other motors, care must be taken to prevent the rated motor current (50/
60 Hz) from exceeding the rated output current of the inverter.
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.
To operate the motor beyond 50/60 Hz, consult the motor manufacturer for
the maximum allowable rotation speed.
When SLV is selected, please set the carrier frequency higher than 2.1 kHz.
At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor
(when selecting sensorless vector control—SLV).
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. The average deceleration torque
varies with motor loss. This value decreases when operating beyond 50 Hz. If
a large regenerative torque is required, the optional regenerative braking
resistor should be used.
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 satisfactory for your application, contact your Hitachi sales representa-
tive.
If operating the inverter at 40 to 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.

sentative.
