*1 : The protection method conforms to JIS C 0920 (IEC60529)
*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 C 60068-2-6:2010 (IEC 60068-2-6:2007).
*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.
*8 : The frequency command is the maximum frequency at 9.8V for input voltage 0 to 10VDC,or at 19.8mA for input current 4 to 20mA.If this characteristic is not satisfactory for your application,contact your Hitachi representative.
*10 : Please be sure to connect DC reactor attached to 1850HF,2200HF,3150HF and 4000HF. (1850HF,2200HF and 3150HF of US/JP Version:The DC reactor is not attached.)
*11 : 1850HF,2200HF,3150HF and 4000HF:The function is not provided.
*12 : SJ700D-3 only.
*13 : The option cannot access new parameters in SJ700D-3.
