(*1) Fuji’s 4-pole standard motor
(*2) Rated capacity is calculated by regarding the output rated voltage as 220V
(*3) Output voltage cannot exceed the power supply voltage
(*4) It is a value in the confition of the career frequency 10kHz and the ambient temperature 45°C.
Selected the inverter capacity such that the square average current in cycle operation is 80% or less of the rated current of an inverter
(*5) The power supply capacity is 500kVA (ten times the inverter capacity when the inverter capacity exceed 50kVA), and the calculation value when connecting with the power supply of %X=5%
(*6) Obtained when a DC Reactor is used
(*7) An acceptable variation of the main power supply and the control power supply assistance input
(*8) The admissible error of minimum resistance is ±5%.
(*9) Type list:
FRN2.2LM1S-7EA : CAN version
FRN2.2LM1S-&EA : DCP version
(*10) The same AC power as the main power supply input is connected for the backup of the control circuit power source
(*11) It is a value in the condition of the career frequency 10kHz and the ambient temperature 455°C.
Use the inverter such that the square average current in battery operation is 80% or less of the rated current of an inverter.
(*12) Braking time and duty cyclw (%ED) are defined by cycle operation at the rated regenerative power as shown in the figure bellow
