The 400V models from –1850 to –4000HFU2/HFE2 (250 to 525 HP) include a DC reactor and
ferrite core.
Footnotes for the preceding tables and the table that follows:
Note 1:
The protection method conforms to JEM 1030.
Note 2:
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.
Note 3:
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.
Note 4:
To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the
maximum allowable rotation speed.
Note 5:
When SLV is selected, please set the carrier frequency higher than 2.1 kHz.
Note 6:
At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor (when
selecting sensorless vector control—SLV).
Note 7:
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 decel 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.
Note 8:
The frequency command will equal 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 representative.
Note 9:
The storage temperature refers to the short-term temperature during transport.
Note 10:
Conforms to the test method specified in JIS C0050 (1999). For the model types
excluded in the standard specifications, contact your Hitachi sales representative.
Note 11:
NEMA 1 applies up to 22kW. An optional wire-entry conduit box is required for
0.4kW to 55kW models to meet NEMA 1 rating.
