*1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2 The rated output capacity indicated assumes that the output voltage is 440V.
*3 The % value of the overload current rating indicated 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.
*4 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within
the setting range. However, the pulse voltage value of the inverter output side voltage remains unchanged at about
the power supply.
*5 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input
reactor and cables).
*6 Totally enclosed structure series ends with -C.
