Getting started

Footnotes for the preceding table and the table 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: EU version inverters (-SFE and -HFE) have integrated EMC filter.

Note6: 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).

Note7: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor.

Note8: 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.

Note9: 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.

Note10: 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 Carrier Frequency Adjustment in accordance with the expected output current level.
