Protective functions

Environmental

conditions

Options

*1: The protection method conforms to JEM 1030.

*2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole).

To use other motors, be sure to prevent the rated motor current (50Hz) from exceeding the rated output current of the inverter.

*3: The output voltage decreases as the main power supply voltage decreases except for the use of AVR function.

*4: Braking resistor is not integrated in the inverter. Please install optional braking resistor or dynamic braking unit when large braking torque is required.

*5: Conforms to the test method specified in JIS C0040(1999).

*6: To operate the motor beyond 50/60Hz, please consult with the motor manufacturer about the maximum allowable rotation speed.

*7: Storage temperature refers to the temperature in transportation.
