(*1) Fuji's 4-pole standard motor
(*2) Rated capacity is calculated by assuming the output rated voltage as 230V for three-phase 230V series and 460V for three-phase 460V series.
(*3) Output voltage cannot exceed the power supply voltage.
(*4) When setting the carrier frequency (F26) to 3 kHz or less. Use the current ( ) or below when the carrier frequency setting is higher than 4kHz and continuously operating at 100%.
(*5) Obtained when a DC REACTOR is used.
(*6) Average braking torque obtained when reducing the speed from 60Hz with AVR control OFF (Varies with the efficiency of the motor.)
(*7) Average braking torque obtained by use of external braking resistor (standard type available as option)
(*8) Voltage unbalance [%] = x 67(IEC 61800-3)
If this value is 2 to 3%, use AC REACTOR (ACR: option).
(*9) The value is calculated on assumption that the inverter is connected with a power supply capacity of 500kVA (or 10 times the inverter capacity if the inverter capacity exceeds 50kVA) and %X is 5%.
