Footnotes for the preceding table and the tables that follow:
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.
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.

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 using the inverter with 3-phase power input, remove the single phase
filter and install a 3-phase filter with the appropriate ratings.
filter and install a 3-phase filter with the appropriate ratings.
Note 6:
For achieving approved input voltage rating categories:
• 460 to 480 VAC – Over-voltage Category 2
• 380 to 460 VAC– Over-voltage Category 3
To meet the Over-voltage Category 3, insert an EN or IEC standard compliant
isolation transformer that is earth grounded and star connected (for Low
Voltage Directive).
• 460 to 480 VAC – Over-voltage Category 2
• 380 to 460 VAC– Over-voltage Category 3
To meet the Over-voltage Category 3, insert an EN or IEC standard compliant
isolation transformer that is earth grounded and star connected (for Low
Voltage Directive).
Note 7:
At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor.
Note 8:
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.

Note 9:
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.

Note 10: If the inverter is operated outside the region shown in the graph to the right,
the inverter may be damaged or its service life may be shortened. Set B083
