• Inverter efficiency is calculated using values suitable for each inverter model. Furthermore, input RMS current
is calculated based on the following conditions.
[FRN0060G2□-4G or lower] Power supply capacity: 500 kVA, source impedance: 5%
[FRN0075G2□-4G or higher] Values commensurate with the capacity recommended by Fuji Electric are
used for calculating the power supply capacity and source impedance.
• The input RMS currents listed in the above table will vary in inverse proportion to the power supply voltage,
such as 380 V.
• The braking circuit current is always constant, independent of braking resistor type (built-in, standard,
10%ED).
