∗1
The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor.
∗2 For the SND rating, the carrier frequency is always 2 kHz.
∗3
The rated output capacity indicated assumes that the output voltage is 440 V.
∗4
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.
∗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
∗6 ND rating reference value
∗7
FR-DU08: IP40 (except for the PU connector section)
∗8
For the power voltage exceeding 480 V, set Pr.977 Input voltage mode selection. (For details, refer to the FR-A800 Instruction Manual
(Detailed).)
