Mitsubishi FR-A820-3.7K-1 General-Purpose Inverter FREQROL-A800

Mitsubishi FR-A820-3.7K-1 General-Purpose Inverter FREQROL-A800

Product Description:

The motor capacity requirement for this particular application is 3.7 kW. The input voltage class is specified as three-phase 200 V.

The output specification is three-phase with a capacity of 6.7 kVA. The dimensions of the motor are as follows: height of 260 mm, width of 150 mm, and depth of 140 mm. The motor also comes with a protective structure.

The output rated current is 17.5 A and the output rated power supply is three-phase 200-240 V.

Rated (Standard Structure Models) 200 V Class:

∗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).
∗10 FR-DU08: IP40 (excluding the PU connector)

Rated (Standard Structure Models) 400 V Class

∗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 440 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).
∗10 FR-DU08: IP40 (excluding the PU connector)
∗11 If 480 V is exceeded, the Pr. 977, "Input Voltage Mode Selection," must be set.
∗12 The regenerative brake capacity can be improved using a commercially available brake resistor. For further details, please contact the Mitsubishi Sales Office.

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.
