∗1 The maximum applicable capacity assumes that Mitsubishi Electric’s standard 4-pole motor is used.
∗2 With the 0.2 kW motor, only the V/F control can be applied.
∗3 The rated output capacity assumes an output voltage of 220 V.
∗4 The percent value of the rated overload current displays the ratio for the rated output current of the inverter.
With repeated use, you must wait until the inverter and motor return to a temperature at 100% load or a lower temperature between use.
∗5 The maximum output voltage never exceeds the power supply voltage. The maximum output voltage can be changed within its range of settings.
However, the wave crest value of the inverter output voltage waveform is roughly √2 times that of the power supply voltage.
∗6 With a built-in brake resistor
∗7 Value based on the ND rating.
∗8 The rated input current is the value at the rated output current. The rated input current varies depending on the value of power supply impedance (including the impedance of the input reactor and wires).
∗9 The value of power supply capacity is the value at the rated output current. It varies depending on the value of power supply impedance (including the impedance of the input reactor and wires).

Applications:
Effective Vector Control Option Required
The displayed protection functions can vary depending on the option(s) installed. To ensure proper function, the option to support vector control must be installed.
PM Sensorless Vector Control
If you have selected PM sensorless vector control, please refer to page 211 for additional information.
Torque Limitation Level
Please note that for models 3 FR-A820-5.5 K (00340) or larger and FR-A840-5.5 K (00170) or larger, the default value is limited to 150% due to torque limitations.
Standard Structure and IP55 Compatible Models
Protection functions are effective only on standard structure models and IP55 compatible models. Please refer to the product specifications to determine compatibility.
Protection Function Limitations
Please be aware that certain protection functions may not work from the initial state or may only work on specific models. For example, function 6 works only on standard structure models, while function 7 works only on IP55 compatible models.
Temperature Limitations
While it may be safe to expose the unit to temperatures outside of the specified range for short periods, such as during shipping, please adhere to the specified limits when in use.
Altitude Limitations
If installing the unit at an altitude exceeding 1,000 m (up to 2,500 m), please note that the rated current must be reduced by 3% every 500 m.
Vibration Limitations
Please note that vibrations greater than 2.9 m/s2 are not recommended for FR-A840-160 K (04320) or larger models.
FR-A800-E Function Limitations
Function 11 works only on the FR-A800-E model.
