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 C0911 (1984). 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

30kW to 55kW models to meet NEMA 1 rating.
