*1 Indicates the maximum capacity applicable to voltage of 690 V.
*2 The rated output capacity is the value with respect to 690 V output voltage.
*3 Total output current of the inverters operated in parallel
*4 The percentage of the overload current rating is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow
time for the inverter and motor to return to or below the temperatures under 100% load.
*5 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.
However, the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about
