∗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
∗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
Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation with the ambient temperature exceeding 40°C(104°F), the
rated output current is the value in parenthesis.
