8.1.2 Three-phase 460 V class series
*1 Standard 4-pole motor
*2 Rated capacity is calculated assuming the output rated voltage as 460 V.
*3 Output voltage cannot exceed the power supply voltage.
*4 Use the inverter at the current enclosed with parentheses ( ) or below when the carrier frequency is set to 4 kHz
or above (F26) and the inverter continuously runs at 100% load.
*5 In the case of inverters with a capacity of 20 HP at an ambient temperature of 45qC (104qF) or above, this
overload capability is assured, provided that the inverter has run continuously with 85% of the rated current.

If this value is 2 to 3%, use an optional AC reactor (ACR).
*7 The value is calculated assuming that the inverter is connected with a power supply with the capacity of 500 kVA
(or 10 times the inverter capacity if the inverter capacity exceeds 50 kVA) and %X is 5%.
*8 Obtained when a DC reactor (DCR) is used.
*9 Average braking torque obtained when reducing the speed from 60 Hz with AVR control OFF. (It varies with the
efficiency of the motor.)
*10 Average braking torque obtained by use of an external braking resistor (standard type available as option)
