Footnotes for the preceding table and the tables that follow:
Note1: The protection method conforms to JEM 1030.
Note2: The applicable motor refers to Hitachi standard 3-phase motor (4p). When
using other motors, care must be taken to prevent the rated motor current
(50/60Hz) from exceeding the rated output current of the inverter.
Note3: 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.
Note4: To operate the motor beyond 50/60Hz, consult the motor manufacturer for
the maximum allowable rotation speed.
Note5: For achieving approved input voltage rating categories:
• 460 to 480VAC – Over-voltage category 2
• 380 to 460VAC – 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).
Note6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor.
Note7: The braking torque via capacitive feedback is the average deceleration
torque at the shortest deceleration (stopping from 50/60Hz as indicated). It is
not continuous regenerative braking torque. The average deceleration torque
varies with motor loss. This value decreases when operating beyond 50Hz. If
a large regenerative torque is required, the optional regenerative braking
unit and a resistor should be used.
Note8: The frequency command is the maximum frequency at 9.8V for input voltage
0 to 10VDC, or at 19.6mA for input current 4 to 20mA. If this characteristic
is not satisfactory for your application, contact your Hitachi representative.
Note9: If the inverter is operated outside the region shown in the graph in the
derating curve, the inverter may be damaged or its service life may be
shortened. Set Β083 Carrier Frequency Adjustment in accordance with the
expected output current level. See derating curve section for the detailed
information of the inverter operating range.
Note10: The storage temperature refers to the short-term temperature during
transportation.
Note11: Conforms to the test method specified in JIS JIS C 60068-2-6 :2010(IEC
60068-2-6:2007). For the model types excluded in the standard specifications,
contact your Hitachi sales representative.
Note12: Watt losses are calculated values based on specification of main
semi-conductors. You must take suitable margin when designing cabinet
based on these values. Otherwise there is a possibility of heating trouble.
