Mitsubishi Electric FR-A820-00046 Instruction Manual page 1114

Inverter rating
The applicable motor capacity indicated is the maximum capacity applicable for use of the
Mitsubishi 4-pole standard motor.
The 0.2 kW motor capacity is applicable under V/F control only.
The rated output capacity indicated assumes that the output voltage is 220 V for 200 V class and
440 V for 400 V class.
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.
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 √2.
Value by the built-in brake resistor
Value for the ND rating
The rated input current indicates a value at a rated output voltage. The impedance at the power
supply side (including those of the input reactor and cables) affects the rated input current.
The power supply capacity is the value when at the rated output current. It varies by the impedance
at the power supply side (including those of the input reactor and cables).
FR-DU08: IP40 (except for the PU connector section)
For the power voltage exceeding 480 V, set Pr. 977 "Input voltage mode selection". (For details, refer
to page 5-211.)
The braking capability of the inverter built-in brake can be improved with a commercial brake
resistor. For the details, please contact your sales representative.
